Description
The Pentax DTRT 150 400v (code 020-654) is the smallest three-phase pump in the DTR high head grinder range. It has a 1.1 kW (1.5 HP) motor drawing 4.4 A at 400v and a 2″ G threaded outlet, with a maximum head of 19.4 metres, 16.0 metres at 150 litres per minute and 9.9 metres at 300 litres per minute.
Hydraulically it matches the single-phase DTR 150 230v, but it needs no capacitors and draws far less current, which makes it the simpler choice wherever three-phase power is on hand. For more head on the same 2″ outlet, step up to the DTRT 200 400v at 22.1 metres or the DTRT 300 400v at 26.1 metres.
The pump body and impeller are cast iron with a cataphoresis paint finish, the grinder is treated stainless steel and the motor shaft is AISI 304 stainless steel. A double mechanical seal with an oil barrier (silicon carbide on the pump side, ceramic and graphite on the motor side) protects the two-pole motor, which has class F insulation and is rated for immersion to 20 metres. The pump stands on a galvanised foot support and comes with 10 metres of H07RN-F cable. There is no float switch, so the pump runs under a separate control panel or level control.
Run it from a three-phase motor starter or control panel with overload protection, which also gives you a way to add level control with float switches.
