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

*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

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
