It is often confusing when sizing a pump union. All the pumps in this section are sized as per USA imperial pipe size reference. Although we refer to 2 inch, 1.5 inch and so on, often the outside diameter of the threaded connection on the inlet and the outlet of the pump will be bigger than the size referred to. The reference is related to the internal bore of the pipe work used to plumb the pump in place. See our guide below...
2.5 inch = 90mm OD, 2 inch = 75mm OD, 1.5 inch = 62mm OD, 1 inch = 48mm OD
A Water Jet Pump, we refer to as a Hot Tub Pump that operates the main Jets in the Spa for massage. With a two speed or dual speed pump the low speed will operate to filter and heat the water and the high speed will act as the boost operation. We would call this pump the filtration pump. A two speed or dual speed boost Spa Pump is a pump not used to filter or heat the Spa water and would usually have a higher rating on the low speed operation.
A circulation pump is designed to run for 24 hrs a day if needed and is also designed to run at minimal output to offer a more economical solution to running and heating your Hot Tub. A circulation pump will in most cases still be connected to the filter and Ozone line and will normally enter the Hot Tub from 1 -- 6 low output Jets.
Hot Tub Water Pumps are mainly found in two frame sizes, 48 frame and 56 frame. This is mainly due to space restrictions although it is thought that 56 frame Spa Pumps offer better durability as they are able to keep slightly cooler when running.
