This energy efficient pump, Balboa's Niagara ( formerly Ultra Jet Ultimax),  meets and exceed the most strict level of municipal noise requirements. This pump is intended as a replacement for common true 4.0 HP 230 volt side discharge pumps that use 2” unions at both the suction and discharge connections.   The pump is normally directly wired to receptacle of spa pack. Save your old pump’s cord so you have the correct connector.  Safety features include auto motor overheat shut off protection.  This pump is a 2-speed pump but can also be used as a single 1-speed 3 HP pump (230 VAC)

Comes complete with two 2" replacement unions.  Drain plug ensures no water is left in the pump body during storage, which is useful for hygienic reasons and also prevents freeze damage where applicable. All Niagara (formerly Ultimax)  pumps have discharge and suction nipples that allow for a side stream flow, for such purposes as an ozonator venturi. If your hot tub uses these nipples, they must first be drilled out on the new replacement pump before they become active.
