How this pitcher pump works

This pump design is based on old fashioned ingenuity that dates back more than 100 years. The pump cylinder holds a plunger with a leather cup that sets above the base flat valve that works as a flapper valve. Directly above the leather cup and inside the plunger cage the plunger weight sits on top of the threaded nut and acts as a check valve. The handle is connected to the plunger and moves the plunger up and down.

When the handle is pulled up it pushes the plunger down against the weighted flat valve (flapper valve). As the handle is pushed down it lifts the plunger, creating a vacuum inside the cylinder causing the flat flapper valve at the base to open pulling water into the cylinder. When the plunger reaches the top of the cylinder the base flapper valve closes due to the weight of the water in the cylinder and water is trapped in the cylinder.

As the handle is pulled upwards again, pushing the plunger down towards the flapper valve again, water is forced out through the plunger weight still keeping water in the cylinder. When the handle is pushed down raising the plunger again, new water is brought into the cylinder forcing the water in the cylinder to exit out through the spout. A constant pumping of the handle creates a continuous water flow at a rate of approximately 1 gallon every 10 strokes.

This hand operated Pitcher Pump will pump water from a water level of 24 feet or less from the bottom of the pump. This distance is measured vertically from the spout of the pump to the actual water level where the water will be pulled from. You will need to deduct 1 foot for every 1000 foot elevation above sea level, and 1 foot for every 50 feet of horizontal pipe distance used in the drop pipe. This pump can be installed on a well, a barrel, or holding tank.

The drop pipe is the piping to be used to attach to the bottom of the pitcher pump and reach into your water source. The drop pipe can be PVC (we recommend schedule 40), galvanized, copper or any other potable (drinking water grade) piping. The bottom of the pump has 1-1/4" fips threads. For optimum water flow the drop piping used should not be smaller than 1-1/4" pipe. 1" piping can be used but will decrease the amount of water volume pumped out through the spout. Your drop pipe should be at least 5 feet longer than the actual water pumping level. This can help to allow for changing well water levels that can happen throughout the year.

The pump should never be operated without water to eliminate damage to the leather cup. Always fill the pump with water (called priming the pump) before operating the pump. Prime the pump by pouring water in the top of the pump until it flows out of the spout. Wait 4 or 5 minutes while the leather cup swells enough to make contact with the pump wall. Using short strokes, raise and lower the handle until the suction pipe fills with water. Add more water in the top of the pump if necessary. If the pump will not prime then check for leaks on the suction side. A leak will prevent the pump from priming.

The use of a foot valve will keep water in the drop pipe and eliminate the need to prime the pump. However, if freezing conditions can exist then the pump will need to be removed from the water source during the freezing season. Or, if the foot valve is removed the handle of the pump can be left in the up position (tied up as high as possible) to cause the pump to self drain. When the handle is lifted as high as possible the check valve (plunger weight) becomes tilted as the plunger is forced down on top of the bottom flat leather weight allowing air into the suction line to break the vacuum and drain the suction line.

If the pump is not used for a long period of time then some evaporation could occur causing the water to fall below the leather and drying out the leather. If the handle was operated water should still be lifted but damage to the leather might occur. If the pump has not been operated for a long period of time it would be best to prime the pump with a couple of cups of water and wait a few minutes while the leather cup swells enough to make contact with the pump wall.
