Boat Boarding Ladder Extension

Boat Boarding Ladder Extension


EXTEND YOUR STEP HANGS ON YOUR BOARDING LADDER
Extend Your Step stays right on
your boarding ladder,
so you never need to store it.

EXTEND YOUR STEP FOLDS WITH YOUR BOARDING LADDER
Extend Your Step stays new-looking and
cleans up easily with soap and water when needed.

Without the EXTEND YOUR STEP
Standing on the bottom rung
of my sailboat’s boarding ladder
requires a big step up from the water.

With EXTEND YOUR STEP
With Extend Your Step it’s much easier for me
to geton board as it extends well into the water.

Many standard boat boarding ladders are simply too short and that causes a lot of frustrating situations.

Have you ever found it difficult to get on your boat with its stock ladder? It may be too short, or perhaps you have mobility concerns.

Or you are getting older and you don’t have the same ability to climb up and down your ladder as before.

In any case, Extend Your Step offers a convenient and easy solution to increase the length of your ladder without major modifications or an expensive total replacement. It’s compatible with many stock boarding ladders and takes just minutes to install.

At 10” wide and 24” long, it provides plenty of extra reach and is made to fit many types of boarding ladders. Made from premium high-density polyethylene, it is far superior than any type of rope ladder in terms of durability, sturdiness and simple convenience. The recommended weight limit should not exceed 230 pounds.

Extend Your Step features wide compatibility:
  • It can fit any type of tubular boarding ladder and flat steps up to 1”, flat or round.
  • It fits most boarding ladders with a rung size up to 1” made by Garelick, AFI, Windline, Seachoice, and it also fits all round rung ladders.
There’s plenty of room for both of your feet on one step. Perhaps you won’t need that much space; you can easily adjust Extend Your Step down in size with a hacksaw and Philips screwdriver as needed.

Extend Your Step makes it much easier to get on and off your boat in a variety of circumstances. There’s no need to risk injuring yourself or others by relying on the shorter stock ladder of your boat. Some of the uses for either of the boarding ladder extensions is a boat swim platform ladder, or pontoon boat ladder extension.

ALL NEW – Extend Your Step Three

You asked for it – a longer and non-moving version of Extend Your Step. That’s exactly what you get with Extend Your Step Three. When attached to the second step of your boarding ladder, Extend Your Step Three won’t swing, while providing you with a convenient ladder extension. This ladder extension is 10” wide and 41” long and fits ladders with up to 1.25” rungs. The recommended weight limit should not exceed 230 pounds.

Troubleshooting Fluid Transfer Pump

Troubleshooting Your Fluid Transfer Pump

Troubleshooting Your Demand Style Diaphragm Pump

Not Priming any air leak or blockage along the suction line well prevent the pump from priming. Check the hose, hose clamps, fittings and strainer. If your suction line checks out, the cause usually centers on a problem with the valves. Open up your pump and verify the valve o-ring is in place and there is not any debree clogging the valves. Valves occasionally swell or lose their resilence. This type of valve damage is not always visible. Luckily valves are relatively inexpensive and easy to replace.

Low Pressure or Automatic Switch not shutting off. Slight swelling of the valves is the most common cause of low pressure or the pump not automatically shutting off. If after replacing the valve and the problem still persists, replace the pressure switch.

Leaking a ripped or cracked diaphragm is normally the cause of liquid leaking out of the pump. Additional damage to the bearings and motor can be avoided if you catch the leak early.

Pump does not respond to electrical power. Bypass the pressure switch by removing the two wires attached to the switch and connect them momentarily together. If the pump turns on your pressure switch requires replacement. If your pump remains lifeless after by passing the switch your motor needs replacing. note: some motors have replaceable brushes this may be your next step. If after replacing the brushes the motor remains lifeless replace the motor.

Low Flow will occur when the impeller is damaged. Bowed, missing worn or ripped blades will reduce flow. A worn cam, wearplate or coverplate will reduce flow. The replacement of these parts, when worn, normally cures the problem. Another cause of low flow is an air leak. This can occur anywhere along the suction line, within the sea strainer, or within the pump. Check all hoses, hose clamps, fittings, gaskets and the pump seal.

Not Priming of all the causes of low flow described above can also prevent the pump from priming.

How to prevent Impeller Failure, the main cause of premature impeller failure involves running the pump dry, with a restricted suction or blocked discharge. Confirm your inlet Seacock is in the open position before starting your engine. You would be surprised how often this simple step is forgotten. Regularly clean you suction strainer, and confirm all old impeller blades are removed when replacing your impeller. These steps will reduce the majority of the system low restrictions.

Troubleshooting Your Centrifugal Pump

Not Priming(for self priming models) any air leak or blockage along the suction line well prevent the pump from priming. Check the hose, hose clamps, fittings and strainer. If your suction lines check out, verify pump shaft rotation and impeller spacing (impeller spacing within a self-priming centrifugal pump is critical). Self-priming centrifugal pumps require liquid in their housing to prime. If your pump has sat long enough for the liquid to evaporate, or your pump was just installed, verify that your pump housing has been filled. Also verify your shaft rotation is the correct way. A self-priming centrifugal pump will not prime when run in reverse.

Low flow the most common reason for centrifugal pumps to experience low flow upon inital start up is reverse rotation. A centrifugal pump will deliver 60% of their designed flow when rotated backwards. An air leak along the suction or line blockage anywhere in the system will reduce flow. Clear all lines, test for leaks, and verify your chosen line size, fittings and valves are not overly restricting your flow.

How to prevent premature seal failure the typical mechanical seal is designed to last thousands of hours. The common causes of premature seal failure include running the pump dry (closed seacock of blocked suction), cavitation (restricting the inlet flow to the pump by reduced line size, clogged strainer or partially blocked or collapsed suction line), thermal shock (a quick change in temperature that shatters the ceramic element of the seal, and often occurs when a pump has been running dry long enough to heat up the seal significantly before fluid is allowed to enter the pump), and deadheading (running the pump with a closed discharge for extended periods of time).
Diagram of the Gear Pump Troubleshooting guide.
Troubleshooting Your Gear Pump

Not Priming any air leak or blockage along the suction line well prevent the pump from priming. Check the hose, hose clamps, fittings and strainer. Dry gears will also reduce the pump's ability to prime. Simply pour a small quantity of your liquid into the suction or discharge sides of the pump and try again. If none of these ideas work, disassemble your pump to inspect for wear as described in the picture.  If excessive wear exists, you will need a rebuild kit or complete pump head.

How to prevent premature pump failure, gear pumps were designed to transfer or spay clean liquids. The close tolerances between both gears and the pump body are the key to it's ability to deliver a strong suction and high discharge pressure. However sand or debris will wear all contacting surfaces or even lock up the pump potentially causing motor or shaft failure.

How Pumps Work

From a page at CLR Marine, How Pumps Work


Diagram of the Centrifugal Pump 
How the Centrifugal Pump Works
a) Liquid enters the inlet port of the pump through gravity or priming and is directed towards the center of the impeller.
b) The Rotating impeller uses centrifugal force to add velocity to the liquid as it is slung off the edges of the blades into the volute casing.
c) The volute configuration converts the velocity energy into static pressure or available pump head as the liquid leaves the discharge port.

The Features of the Centrifugal Pump
High Volume Flow, Centrifugal pumps deliver a high volume of flow with smooth non-pulsating delivery.
They are Low Maintenance due to the wear on them is minimal and they are easy to disassemble and have few moving parts.
The Centrifugal pump has a Low Power Consumption and is the most efficient pump for moving large volumes of liquid.
Diagram of the Diaphragm Pump
How the Diaphragm Pump Works
a) As the piston diaphragm is pulled away from the housing, the cavity increases in size. This creates a vacuum that draws in the liquid through the one way inlet valve.
b) As the diaphragm is pushed toward the housing, the cavity decreases in size which forces the liquid out through the one way outlet valve.

Features of the Diaphragm Pump are that it is Dry Running it can run indefinitely without damage.
The Diaphragm pump is Self-Priming and can lift up to 15 feet under ideal conditions.
The Diaphragm Pump is also Self-Adjusting air operated diaphragm pumps automatically adjust their speed as viscosityfluctuates.
Diagram of the Flexible Impeller Pump
How the Flexible Impeller Pump Works
a) As the flexible impeller blades leave the cam, the cavities between them increase in size and create a vacuum which draws in the liquid.
b) Once the blades clear the inlet port, the liquid is captured in the cavity between the blades and the housing.
c) As the blades contact the cam and bend , the cavity between them is reduced in size and the liquid is forced out the discharge.

Feature of the Flexible Impeller Pump is that it is Self Priming it quickly primes from a dry start or a wet start and will lift up to 15 feet when wet.
It has Low Shear and Batching as a smooth gentle pumping action for liquids of low to high viscosity.
Diagram of the Plunger Pump
How the Plunger Pump Works
a) As the crankshaft (1) rotates, the connecting rod (2) pulls back the plunger (3) from the liquid chamber (4) within the manifold which increases the chambers size.
this creates a vacuum that draws in liquid through the inlet valve (5).
b) As the crankshaft's rotation continues, the connecting rod (2) pushes the plunger (3) toward the liquid chamber (4) reducing the chambers size. This forces the liquid out of the discharge valve (6).

Features of the Plunger Pump
High Pressure creates pressures up to 15,000 psi can be achieved.
Clean Liquids close fitting components require clean non-abrasive liquids.
Durability the ceramic plungers and the oil filled crankcase ensures a long operating life.
Diagram of the External Gear Pump
How the External Gear Pump Works
a) As the gears separate on the inlet side of the pump, cavities are created between the gear teeth which create a vacuum that draws in the liquid.
b) Once the teeth clear the inlet port, the liquid is captured between the gear teeth and the housing.
c) As the teeth mesh, the liquid is squeezed out of the cavity and forced out the discharge port.

Features of the External Gear Pump.
Metering, thin to viscous liquids can be dispensed in a smooth repeatable flow.
High Pressure up to 500 psi can be achieved with a low to high viscosity liquids.
Clean Liquids close fitting gears require clean non-abrasive liquids.
Diagram of the Vane Pump
How the Vane Pump Works
a) Centrifugal force (and or springs) keeps the blades in contact with the housing as each blade leaves the upper eccentric area. Liquid is drawn in as the size of the cavity between the blades and housing increases during the rotary motion.
b) Once the blades clear the inlet port, the liquid is captured in the cavity between the blades and the housing.
c) As the blades contact the eccentric portion of the housing and are pushed back into their slot, the cavity between the is reduced in size which forces the liquid out the discharge.

Features of the Vane Pump
Self_Priming lifts liquids up to 3 feet with higher lifts possible with some models.
Low to Medium Viscosity thin to medium viscosities are easily handled.
Simplicity with few moving parts to fail or replace.
Diagram of the Lobe Pump
How the Lobe Pump Works
a) The motion of the counter rotating rotors create a partial vacuum which draws the liquid smoothly into the pump chamber.
b) As the rotors revolve, liquid is captured between the rotor cavities and the outer housing.
c) The liquid is forced out the discharge as the rotors mesh and eliminate the cavities the liquid occupies.

Features of the Lobe Pump
Efficient Improved efficiency and sterilizability over the traditional lobe pump design. Longer sealing surfaces ensure high volumeetric efficiencies with thin liquids.
Solids Handling gentle low shear solids and abrasive handling.
Wide Viscosity Range from 1 to 1,000,000 centipoise.
Diagram of the Air Operated Diaphragm Pump
How the Air Operated Diaphragm Pump Works
a) Compressed air powers the piston (1) moving it right to enlarge cavity "a". This action draws in liquid through the check valve (2).
b) While the piston (1) enlarges cavity "a" it compresses cavity "b" forcing liquid out the one way check valve (3) toward the discharge.
c) Once the piston (1) has fully extended, it is redirected (by compressed air) to compress chamber "a" (forcing liquid out) and enlarging chamber "b" (drawing liquid in).
d) Once the piston (1) has fully extended to the left the cycle repeats as compressed air redirects the piston (1) back to the right.

Features of the Air Operated Diaphragm Pump
Dry Running this pump can run dry indefinitely with out damage.
Dead Head this pump will simply stall and will not be damaged when the discharge is blocked.
Self-Priming this pump can lift up to 20 feet under ideal conditions.
Diagram of the Roller Pump
How the Roller Pump Works
a) Centrifugal force slings each roller out against the housing as each roller leaves the upper eccentric area. Liquid is drawn in as the size of the cavity between the rollers and the housing increase during this rotary motion.
b) Once the rollers clear the inlet port the liquid is captured in the cavity between the rollers.
c) As the rollers contact the eccentric portion of the housingand are pushed back into their slot, the cavity between the rollers is reduced in size which forces the liquid out the discharge.

Features of the Roller Pump
Abrasive Handling the roller design allows the handling of powders in suspension.
High Pressure up to 300 psi can be achieved.
Simplicity with few moving parts to fail or replace.
Diagram of the Peristaltic Pump
How the Peristaltic Pump Works
a) As the rollers compress the hose and move away from the inlet a vacuum is created drawing in the liquid.
b) The rollers work together to capture liquid between the pinched areas of the tube and move the liquid toward the discharge.
c) The front roller leaves the hose, opening the captured area while the back roller pushes the liquid out of the discharge.

Features of the Peristaltic Pump
No Liquid Contact liquid comes in contact only with the hose utilized within the pump.
Self-Priming can lift up to 25 feet.
Viscous and Abrasive Liquids designed to handle viscous, corrosive, abrasive and high purity solutions.
Diagram of the Progressing Cavity Pump
How the Progressing Cavity Pump Works
a) Liquid is drawn into the suction of the pump as the corkscrew shaped rotor revolves within the rubber stator.
b) Liquid is captured in the cavity between the rotor and stator. This cavity travels toward the discharge during rotation.
c) The cavity opens into the discharge chamber and delivers its contents as it reduces in size. Liquid is forced out the discharge as more liquid is delivered by continued rotation.

Features of the Progressing Cavity Pump
Abrasive Handling rotor and stator design allows handling of abrasive and or viscous liquids.
Low Shear smooth gentle pumping action enables the pumping of shear sensitive and solid en-trained liquids.
High Pressure up to 600 psi can be achieved with low to high viscosity liquids.
Diagram of the Regenerative Turbine Pump
How the Regenerative Turbine Pump Works
a) Liquid enters the suction port (a) and is pushed forward by the blades of the impeller (b) in an orderly circular flow around the periphery of the housing.
b) The circular liquid flow in the side channels (c)occur many times during one revolution resulting in 10 times or more discharge pressure than from similar diameter impeller turning the same speed in a centrifugal pump.

Features of the Regenerative Turbine Pump
High Head with Low Flow produces high head at low flow without damaging pump components.
Continuous Duty designed to run 24 hours a day 7 days a week.
Compact more compact than multistage centrifugal's that deliver the same flow and head.
Entrained Air Handling up to 20%.
