Hot Tub Pump Identification

Anatomy of a pump.

A pump in lamens terms consists of two main components: the wet end which contains the impeller, which moves the water, and an electric motor (the dry end) which turns the impeller. All motors at poolandspacentre.co.uk are supplied under European guidelines.

The below video overviews the Waterway brand of the wet end, alternatively it could be an Aquaflo - very similar in design and the Waterway pump is an exact replacement in the 2" suction version. You can view here How to identify an Aquaflo Wet End, but if you want an Aquaflo pump and are having difficulty getting the exact one you require then please email us on info@poolandspacentre.co.uk

How do I locate the right pump for me?

Identifying your replacement pump is easy and very quick, but we need all this information to process your order efficiently.

Frame Size.

If you have space in your hot tub, always go for a 56 frame motor, it's a better more reliable option in the long run, offering better durability as they are kept slightly cooler when running.

Or identify off the motor label (if present) - the label should tell you the frame size

One Speed or Two Speed.

Next, we need to ascertain how many speeds your motor has, it will be either one or two speeds. If your motor has one RPM number it is one speed and obviously, if it has 2 RPM (GIRI) numbers then it is two speeds. Make a note of these numbers. Typically 2850 / 1425 for 2 speed or 2800 for 1 speed

Horsepower.

The Horsepower, if shown on the label, will be great but we need to double-check the motor company's information and we do this by looking at the amp range, this gives us a more realistic picture of the motor's horsepower as some Spa companies over-inflate the horsepower.

230 Volts 7 - 8 amps = 1.5 Horsepower (HP)
230 Volts 9 - 10 amps = 2.0 (HP)
230 Volts 10 - 11 amps = 2.5 (HP)
230 Volts 11 - 12 amps = 3.0(HP
230 Volts 14 - 15 amps = 4.0 (HP)

Wet End Information

Now it is time to identify the form of the pump and we do this by specifically identifying the wet end: A spa pump will be either Side Discharge (90% of UK pumps), or centre Discharge.

Finally, for the wet end, we look at its orientation:

To Identify what the wet end makes, please look for a number 315-1220 embossed on the wet end rear- this identifies it as a Waterway product (75% of the UK market)
