Troubleshooting

Pump not drawing liquid

Ensure the pump is fully submerged in the liquid. Check for blockages in the intake tube or pump mechanism. Verify that the bung adaptor creates a good seal with the drum.

Leaking from plunger seal

Inspect the PTFE seals on the plunger rod for wear or damage. Tighten any visible fittings. If seals are compromised, they may need replacement.

Reduced flow rate

Clean any residue from the intake tube and pump. Ensure the liquid is not too viscous. Check for air leaks in the system.

Pump is difficult to operate

Flush the pump with clean water or a suitable solvent. Ensure the liquid being pumped is within the compatible range and not excessively thick. Check for any obstructions.
