Problem
Remedy
Insufficient Flow
1. Clogged, collapsed, or undersized suction tube and/or filter
Pumps are intended for use with supplied rigid line suction line and/or filter (where applicable).
Verify line and/or filter are clean, not damaged, and the correct size for suction port connection
2. Also see below “Pump does not prime”
Check and repair as necessary
Pump does not prime
NOTE: To aid priming,
fill pump casing through
discharge port prior
to operation
*1. Unsuitable suction line
Pumps are intended for use with the suction line supplied. Long or collapsible suction lines may
slow or stop priming. Use short length rigid tubing similar in diameter to ·suction port. (Maximum
pump height above liquid level is 36 inches)
∆
2. Shifted or worn rotor
Loosen all cover bolts. View pump from side with suction/discharge ports in vertical position and
on right-hand side. Reposition rotor by grasping covers and sliding towards 3 o’clock position.
Do not use excessive force. Hold in position and retighten cover bolts
3. Suction line above liquid
Suction line end must remain completely below fluid surface
4. Damaged/worn pump parts
Remove pump cover and inspect for broken or worn parts. Components
should have smooth finish, no large grooves or voids. Replace damaged parts
5. Pump air leakage
Inspect pump cover(s) and seals for leaks. Tighten fasteners and replace gaskets and/or seals
6. Suction line air leakage
Seal all threaded suction line connections with Teflon” tape or equivalent sealant
7. Pump speed to slow
Rotate pump handle more rapidly until pump primes
8. Clogged suction line and/or filter
Clean suction line and/or filter
Handle difficult or
impossible to move
1. Pump has not been used for an extended time
Remove pump cover and inspect for deposits on components and or corroded parts. Clean or
replace parts. Flush pump with appropriate solvent prior to long periods without use
2. Remove pump cover and inspect internal parts.
Replace worn or damaged components
(*) For pumps supplied without suction/discharge lines.
