Leakage at
Tubing
Connections
1. Worn tube ends
2. Chemical attack 1. Cut off end of tubing approximately one inch
(2.5cm) and reconnect
2. Consult your seller for alternate material
Leakage at
Fitting
1. Loose fittings
2. Broken or twisted gasket
3. Chemical attack 1. Tighten hand tight. Replace gasket if hand
tightening does not stop leakage
2. Check gaskets and replace if broken or damaged
3. Consult your pump supplier for alternate material
Pump Loses
Prime
1. Dirty check valve
2. Ball checks not seating or not sealing
properly
3. Solution container allowed to run dry
4. Chemical outgassing 1. Remove and replace or clean off any scale or
sediment
2. Check seat and ball checks for chips, clean gently.
If deformity or deterioration is noted, replace part
with proper material. Resulting crystals can hold
check valves open, therefore, the valves must be
disassembled and cleaned
3. Refill the tank with solution and prime. See 5.0
Start-up and Operation Section
4. Bleed gas, use flooded suction and maintain
chemical at room temperature (approximately 20˚F)
to minimize outgassing
Pump will
not Prime
1. Too much pressure at discharge
2. Check valves not sealing
3. Output dials not set at maximum
4. Suction lift height too much. Maximum
5ft (1.5m)
5. Pump equipped with spring loaded high
viscosity valves 1. Turn off all pressure valves, relieve system
pressure then loosen outlet tubing connection at
discharge point. Remove discharge valve cartridge.
Dampen ball check and valve seats with a few drops
of solution. Set pump dial to maximum rate. When
pump is primed, reconnect all tubing connections
2. Disassemble, clean and check for deterioration,
damage or swelling. Reassemble and wet the valve
assembly, then prime. See 5.0 Start-Up and
Operation Section.
3. Always prime pump with output dial set at
maximum rated capacity.
4. Decrease suction lift or pull vacuum on pump
discharge until pump is primed
5. Loosen discharge valve to aid in priming, take
necessary safety precautions for spills or apply
vacuum to pump discharge
