Centrifugal pumps
Function: Pumps are used for transfusion of aggressive liquids. Those are single-step pumps with spiral housing and open rotor. All pump parts that are making contact with fluid are made of durable materials. The pump is directly connected to electric motor spindle.
MATERIALS:
basic: PEHD, PP, PVDF,
sealings: EPDM, FPM - viton,
mechanical sealing: ceramic/mod. PTFE.
APPLICATION TEMPERATURE: EHD: -20° to 60°C, PP: -20° to 80°C, PVDF: -40° to 120°C.
PIPELINE CONNECTION: flange, connector with thread G, NPT, M.
STANDARD:
