Description
The Pentax DTR 150 230v (code 020-650) is the entry point to the DTR high head grinder range: a single-phase 1.1 kW (1.5 HP) submersible sewage pump with a 2″ G threaded outlet. Pentax gives it a maximum head of 19.4 metres, falling to 16.0 metres at 150 litres per minute and 9.9 metres at 300 litres per minute, and a full load current of 11.5 A at 230v.
It suits a domestic or light commercial sump where the lift to the sewer is beyond a standard sewage pump but a three-phase supply is not available. If you need a few more metres, the DTR 200 230v is the same size pump with a 1.5 kW motor and 22.1 metres of head. With three-phase power on site, the DTRT 150 400v has the same hydraulics and draws 4.4 A.
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.
As a single-phase pump it needs external capacitors: Pentax specifies a 35 µF run capacitor and an 80 µF start capacitor with a circuit breaker. Call us and we will confirm the right control arrangement before you order.
