Product overview

The Pedrollo MKm 3/3 is a 0.75 kW (1 HP) vertical multi-stage centrifugal pump on a 230 V single-phase supply, covering 10 to 80 l/min with a working head of 51.5 m down to 29 m. Several impellers in series build pressure in a compact, upright pump.

The MK range comes in three hydraulic sizes, the MK 3, MK 5 and MK 8, each in several versions, so you can match the flow and head your system needs. The suction body and delivery port are cast iron with cataphoresis treatment, with an AISI 304 stainless steel outer sleeve, Noryl impellers and diffusers, AISI 304 diaphragms with wear rings and an AISI 431 shaft. Rated for liquid from −10 to +60 °C and a maximum working pressure of 11 bar. An optional flange kit (2113430) is available.
