Varisco Positive Displacement Gear Pump V Series

VARISCO V Series

V series positive displacement internal gear pumps are suitable for pumping liquids of any viscosity. Solids cannot be handled, but the pumps can cope with abrasive liquids.

FEATURES

• Constant capacity, directly proportional to the rotation speed and virtually independent of the pressure.
• Smooth flow, without pulsations or pressure peaks which could cause vibrations in the pipework.
• Versatility. By adjusting the axial position of the rotor, the same pump can handle water-thin liquids or high viscosity liquids such as bitumen, molasses, resins, polymers, etc.
• Reversibility. By inverting the direction of rotation, the flow of liquid is reversed. Full performance is available in either direction of flow.
• Self-priming. The high vacuum created by the pump permits rapid self-priming at the maximum height made possible by the physical characteristics of the pumped liquid.
• Simplicity. Only two moving parts: the rotor and idler gears, and only one shaft seal.
• Rugged, heavy duty construction. Low rotor and peripheral speed. External pedestal bearing housing with oversize ball bearing to take axial and radial loads.

OPERATING RANGE

• From 20 to 100.000 (mm2/s - cSt)
• Capacity from 3,8 m3/h to 350 m3/h
• Pressure handling from 8 bar to 20 bar
