Direct Water Pump — Model Range

Choosing a TP320 or TP325 Direct Water Pump

Direct water pumps are compact, single-phase pumps used to move and pressurise clean water in domestic installations. The TP320P(T) and TP325P(T) share the same 0.37 kW motor and hydraulic performance and differ in connection size: the TP320P(T) has 3/4 inch inlet and outlet ports, while the TP325P(T) has 1 inch ports. Choosing between them is therefore mainly a question of matching the existing pipework.

At 50Hz on a 200 to 240 V supply both models deliver a maximum head of 35 m and a maximum flow of 35 L/min. The 60Hz versions, wired for 110/220 V, give up to 40 m head and 42 L/min. Each model is offered in a standard version and an anti-microbial version, identified by a B at the end of the model code.

Construction is aimed at domestic water. The impeller is made of brass, which offers better resistance to heat and friction than standard alternatives, and the pump body is plastic to protect the hygiene of the water being pumped. A built-in thermal overload protector shuts the motor down if it overheats. Unlike the automatic booster range, no pressure tank or pressure switch is listed for these models, so consider the automatic booster pumps if you need the pump to start and stop on demand.
