Straighten suction line so as to eliminate high
spots
Inspect foot valve screen and assure that foot
valve is in a vertical position below fluid level
Maximum suction lift is 5 feet with water or fluids
of similar specific gravity; less with heavier
liquids such as acids. Mount pump in a lower
position relative to the chemical container.
Check fittings. Over tightening may cause
restriction. Conversely, if any leakage occurs,
pump will suck air and fail to prime.
Inspect check valves in fluid end for cleanliness.
Clean or replace as necessary.
Inspect suction tube through its full length to
assure that there are no kinks or other
restrictions
Check fluid level in chemical supply tank
Check suction line for obstructions, clogging,
kinks or pinch points
Clean or replace foot valve screen
Replace diaphragm, making sure that it is
screwed on fully to shoulder of shaft
Consult factory
Inspect or add anti-siphon valve. This is caused
when system is in a vacuum condition.
Consult factory
Check outlet with meter to assure that 95-135
VAC is present on 120V systems and that the
power supply cord is in good condition and
plugged in
Consult dealer or factory
