ZP gear pumps

For circulating oil lubrication systems

ZP gear pumps with a constant flow direction, with a right-hand (ZP12-2 and ZP1) and left-hand (ZP1-S1) shaft rotation direction. Flow rate is specified for a working viscosity of 140 mm2/s and back pressure of 5 bar (72 lb/in²). Allows the use of direct drive.

ZM pumps — these are ZP pumps driven by an electric motor.
