The pumps prime automatically in heavy conditions with remarkable suction lift. The suction pipe vacuum is 500 – 600 mmHg.
The pumps can run in either direction with identical performance.
The spring mechanism allows the pumps to operate over a wide viscosity range, to handle solid particles in suspension and to adjust working clearances automatically for wear or thermal dilatation.
A low rotating speed allows the pump to handle highly viscous liquids and delicate shear sensitive liquids.
Flow starts from 1m3/h and differential pressure of 8 bar maximum. Pumping temperature up to 200°C and viscosity up to 12 000cP
