Frequently Asked Questions

Can the Delavan 5840-114E plug into a standard outlet?

Yes. It has a 115 VAC permanent magnet motor with a 6 foot lead and plug, and it draws a maximum of 1.5 amps, so it runs from an ordinary household or shop outlet.

What does "bypass design" mean on this pump?

When you close the outlet, an internal bypass valve recirculates liquid inside the pump head instead of shutting the motor off. The pump keeps running, which suits continuous-duty jobs. Delavan recommends adding a motor heat sink for long continuous runs.

What size are the inlet and outlet ports?

The 5840-114E has 1/2" FNPT (female NPT) threaded inlet and outlet ports, which accept standard 1/2" male pipe fittings or hose barbs.

Is the 5840-114E safe for drinking water?

It is certified to NSF/ANSI Standard 61 for drinking water system components and NSF/ANSI 372 for lead-free plumbing, so it is suitable for potable water applications.

Can this pump run dry or lift water from below?

Yes. It is a 5-chamber positive displacement pump that can be run dry and has self-priming capability up to 14 feet. Maximum liquid temperature is 140°F.
