ZPU 09/09A

Electrically operated piston pump for circulating oil systems

The ZPU 09/09A high-pressure pumps are designed for use in hydrostatic and hydrodynamic (start-up phase) lubrication systems. They also may be used in oil supply systems, blocking oil systems and regulation and control oil systems. The pump is suitable for oils with viscosity of 20 to 460 mm2/s. The pump shows a housing, of 8 l (16.9 pts) capacity, with a pump element and a flange with outlets and return lines. All lines are connected to a 3-phase, multi-range or 500 V motor. The pump can be delivered with one or two outlets.
