Questions & Answers

Is this pump self-priming?

No. This is a centrifugal pump. When used as a submersible pump, it must be placed in the liquid. When used inline, it must be gravity-fed or primed via a hand/foot pump.

How do I switch it from submersible to inline?

Simply remove the clip-on strainer at the base to expose the inlet port for hose connection. This allows for direct inline boosting in your plumbing line.

What is the recommended run time?

This pump is designed for intermittent duty with a recommended maximum continuous run time of approximately 20 minutes to ensure motor longevity.

Note: Please verify your requirements against the technical specs provided above. This pump is a high-quality aftermarket solution from Seaflo, stocked at 4boats.co.uk.
