Electric Pumps
CZ series
Gear pumps

The CZ Pump Series has been designed for pumping of cooling liquid for machine tools and especially for pressure lubrication of bearings.  The viscosity of the pumped liquid can be max 115mm2s-1  and its temperature form 0°C to 60°C. The maximum size of impurities can be 0.1mm. The pumps are flanged suitable for fitting directly onto the tank with the pumped liquid. The position of the suction opening in the tank must such that no impure oil gets circulated.  The bypass tube must be positioned in the tank so it does not cause excessive ripple.

4CZA PUMPS = Vertical execution
4CZB PUMPS = Horizontal execution
