Spa circulation pumps

A circulation pump moves water through the filtration and heating circuit of a compatible spa. This collection brings together Laing, LX, Waterway, Gecko, Hot Spring and Bullfrog models to replace a pump dedicated to this circuit.

How do you choose the right circulation pump?

• Part number and spa: Note the pump’s full part number, as well as the spa’s model, year and serial number.
• Power supply: Check the voltage and frequency on the nameplate. A 115 V version is not automatically interchangeable with a 230 V version. Dual-voltage models must be configured according to their instructions.
• Connections: Check the fitting type, diameter, orientation, and the height of the inlet and outlet.
• Installation: Compare the connector, cord, mounting hardware, and available space. Included unions, gaskets, and cords vary by listing.

Different sizes for different circuits

The Laing E10 is available here in 115 V and 230 V versions, with ¾-in barbed fittings. The Waterway Tiny Might uses 1-in unions, while the LX 48WTC0153C-1A has 2-in fittings. These sizes must be checked carefully; the pumps are not directly interchangeable.

For the Hot Spring E5 and Bullfrog 65-04454 parts, also confirm compatibility using the spa’s model and serial number.

Circulation or massage jets?

A circulation pump and a jet pump serve different purposes. See our spa pump collection to compare applications. If you’re unsure, send us a photo of the nameplate and connections on your current pump before ordering.
