Product overview

The Pedrollo WRm 50/125-SB is a 0.55 kW (0.75 HP) in-line close-coupled centrifugal pump on a 230 V single-phase supply, covering 100 to 500 l/min with a working head of 13.5 m down to 6 m. The suction and delivery ports are the same size and sit on the same line, so the pump fits straight into the pipe run.

WR pumps transfer clean water free from abrasive particles in heating, air conditioning, cooling and circulation systems. The impeller is mounted directly on the motor shaft. Cast iron pump body and cover with cataphoresis treatment, AISI 304 stainless steel impeller, AISI 431 shaft and a graphite / silicon carbide / EPDM mechanical seal. Rated for liquid from −10 to +110 °C and a maximum pressure of 10 bar (PN10) in the pump body.

Frequently asked questions

What does in-line mean?

The suction and delivery ports are the same size and on the same line, so the pump fits straight into a pipe run without changing direction.

Can it handle hot water?

Yes, liquid from −10 to +110 °C, with a maximum pressure of 10 bar in the pump body.

What are the port sizes?

Flanged: DN40 on the WR 40/125, DN50 on the WR 50/125 and DN65 on the WR 65 sizes. A counterflange kit is available on request.
