DESIGN FEATURES
Pump housing and motor support – cast iron. PN10 flange connections with threaded holes for pressure gauges or control sensors. Impeller – technopolymer, mechanical seal – graphite/ceramic. The pumps are equipped with an air-cooled asynchronous electric motor: four-pole for KLM and DKLM and two-pole for KLP and DKLP. The electric motor of single-phase models has built-in overload protection. Three-phase electric motors must have overload protection in accordance with current regulations. In twin models, a check valve is built into the hydraulic housing to prevent fluid flow during operation of one of the pumps; A blank flange is supplied as standard with twin pumps.
