The ‘R’ Series Gear pump is a rotary positive displacement pump with positive pressure characteristic. The capacity of the pump varies directly with speed but remain constant against pressure, however due to running clearance between the casing & impeller some liquid always by-passes to suction causing slip, which depends upon the differential pressure, viscosity of the liquid & clearance allowances. The pump does not develop pressure on it’s own but has capacity to over come any back pressure on it with out a substantial drop in capacity. ‘R’ Series Gear Pumps are capable of handling any viscosity. Slippage reduces with viscosity but the viscous power increases. The pump has a self-priming capability but some net positive suction head (NPSH) is always required depending upon the viscosity & pump speed to avoid cavitation.
