Description
The Pentax DTRT 200 400v (code 020-656) is a three-phase submersible high head sewage grinder pump with a 1.5 kW (2 HP) motor drawing 5.1 A at 400v and a 2″ G threaded outlet. Pentax gives a maximum head of 22.1 metres, 19.1 metres at 150 litres per minute and 13.4 metres at 300 litres per minute.
It sits between the DTRT 150 400v, which tops out at 19.4 metres, and the DTRT 300 400v, which reaches 26.1 metres. All three share the same 2″ outlet and body size, so you can move up or down the range without changing pipework. The DTR 200 230v is the single-phase version with the same performance.
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.
