VD-40Internal Eccentric Gear Pump

VD-40 Internal Eccentric Gear Pump

VD-40 internal eccentric gear pump for bitumen, fuel oils, resins and other viscous fluids. Flow up to 5.0 m³/h at 1450 rpm (≤ 165 cSt); differential pressure up to 16 bar, DN40 suction and discharge, viscosity 10 ~ 55,000 cSt, temperature 0 ~ 230 °C.

VD Series Internally Eccentric Pumps Catalog

VD-40 is a positive displacement transfer pump working on the internal eccentric gear principle. The volume formed between the driven outer rotor and the freely rotating inner gear expands on the suction side to draw the fluid in and contracts on the discharge side to push it out. Flow is proportional to speed and independent of pressure. Efficiency rises with viscosity because internal slip decreases. The foot mounted casing carries the shaft in fluid lubricated plain bearings; the compact construction suits direct coupling to a standard motor.
