Electric Pumps
COV series
High pressure pumps

COV Pumps are designed for pumping of cooling liquid for machine tools. The viscosity of the pumped liquid can be maximum 90mm2s-1 (12°E) and its temperature form 0°C to 60°C. The maximum size of impurities can be 0.1mm. The pumps are not suitable for pumping of flammable or combustible liquids or used in explosive environments. 
The pumps are flanged suitable for fitting directly onto the tank with the pumped liquid. The maximum and minimum immersion is to be determined from the pump drawing. The pumps are not suitable for pumping of flammable or combustible liquids or used in explosive environments. The maximum size of impurities can be 0.1mm. The pumps are usually supplied primed with S2003 synthetic primer.
