Pump Performance Depends On an air tight diaphragm, valve assemblies that seal well on the pump inlet and discharge
valve seats and inlet plumbing that is air tight all the way to the point it is submerse in the liquid. If the pump is not pumping
check first for anything blocking the hose. If it is clear then check the pump by:
1. Removing all hose and fittings from the pump.
2. To check the discharge valve assembly and diaphragm put your hand tightly over the pump inlet and pull back on the
handle. You should feel a vacuum suction and if the discharge valve assembly and diaphragm are working properly, you
should not be able to raise thediaphragm all the way. If you do not feel any suction, do the same thing again and listen for
air being sucked in around the diaphragm. If you hear air movement, inspect for loose bolts or warn diaphragm. If you
hear no air movement, remove the discharge chamber and inspect the valve assembly and valve seat. Clean or replace
the valve and clean or resurface the valve seat as appropriate.
3. To check the inlet valve assembly raise the diaphragm; put your hand over the discharge and push forward on the
handle. If the inlet valve is sealing properly, you should feel the pressure against your hand. If you don't, then remove the
inlet chamber and inspect the valve assembly and valve seat. Clean or replace the valve and clean or resurface the
valve seat as appropriate.
4. When you are sure the pump is working properly and the pump still will not pump liquid, check the inlet plumbing for
leaks. Depending on the height above the liquid even one unsealed fitting can prevent liquid from getting to the pump.
PUMPS USED FOR CRITICAL APPLICATIONS SHOULD BE INSPECTED AND TESTED OFTEN
Visually Inspect Pump Inside and Out for Corrosion and Wear. Oil pivot pins. Replace Parts as Required.

CAUTION
Special Applications - Edson pumps are used for many
diverse applications. Some may require special parts or
maintenance procedure. i.e.. pumping liquid with gasoline
or other fuels requires using Viton diaphragms and valves.
If you have any questions regarding procedures for your
application, call Edson customer service.
