PUMPS can be installed on a well pipe,a well drop pipe an open well, a tank, a spring, acistern, a barrel, etc. These pumps may also be used as a hand held bilge pump, barrel/drum pump or for initial priming a jet or centrifugal pump.OASIS Hand Lift Pumps Model Numbers WP2 is a positive displacement suction lift pump. It will give good performance on pumping application where the suction lift does not exceed 20 feet. 50 feet is possible with the model WP2D & DC280 DEEP WELL KIT -
Installation
INSTALL pump on well pipe, or drop pipe. 2" PVC Drop Pipe recommended
TEFLON tape or a good quality thread, sealant should be used on all threads.
Make up threads on pump hand tight or enough to prevent leaks.
Prime until all air is eliminated an pump is primed.
A small amount of water must be added to the pump for initial prime, pump handle until all air is eliminated and pump is fully primed.
This pump needs to be primed before every use. Keep a pitcher (not included) of water near the pump for this purpose.
Pump the handle up and down while pouring about a quart of water into the top of the pump to prime it and start the water flow.
Do not stop pumping the handle until finished! Stopping, even momentarily, will cause the pump to lose its prime and no longer work until primed again.
Refill the pitcher. Then, continue pumping as needed.
The use of a foot valve will maintain permanent prime.
Lower to desired depth (below water) raise and lower in short strokes until suction pipe fills with water and pump is primed.
Pressure Application
The WP2 and WP2D are designed for pressure applications. They have a packing nut on the plunger rod and an "O" ring seal on the mounting cap. On permanent installations a tee must be installed at or near the pump for priming.
Hand tight only on packing nut, do not over tighten. Assemble handle and plunger bolts loose for movement.
The discharge on these pumps is 1-1/4" female iron pipe thread. Screw a 1-1/4 Male IPT X Insert hose elbow adapter on the pump discharge and turn the elbow up to prime and down to pump or divert water in any or to attach the a discharge hose.
On permanent installations a tee must be installed at or near the pump for priming.
Freezing Weather
In freezing weather the internal flapper valve and plunger (both are made of leather or composite material) may freeze to the pump body. If you start
pumping, they may tear, making the pump inoperable. If you
suspect that your pump is frozen you will need to thaw it out by:
Unscrewing it from the connector and bringing it into a warm spot or soaking it in a pail of warm water.
Pouring warm water into the top and letting it sit for a few minutes.
Opening the pump and freeing the individual components
by hand.
Freezing Protection
If you use it your hand pump frequently and want water without priming, you should install a foot valve at the bottom end of the pipe. The use of a foot valve will maintain permanent prime. We suggest a foot valve if your water is 10' down or deeper. A foot valve is a one-way valve that lets water in but not back out again, so it keeps the pipe full of water. The problem with it comes with cold weather when water in the pipe freezes, rendering the whole apparatus inoperable and possibly splitting the pipe.
If you use a foot valve then you can prevent the pump and pipe from freezing only by removing the pump from the well and keeping the water in the well below the frost line.
