Del Pd Pumps & Gears [P] Ltd. Supplies Rotary Gear Pump with Modified Tooth Profile. Del Pd Pumps & Gears [P] Ltd. Manufactures rotary positive displacement pump. Rotary Gear Pump with Modified Tooth Profile is provided with positive pressure characteristic. The capacity of Rotary Gear Pump with Modified Tooth Profile 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 sleep, which depends upon the differential pressure, viscosity of the liquid & of course the workman-ship. The pump do not develop pressure on it`s own but has capacity to over come the back pressure on it way with out substantial drop in capacity. This pump is capable of handling any viscosity the sleep reduces with viscosity but the viscous power increases. It has a self-priming capability but some net positive suction head [NPSH] is always required depending upon the viscosity & pump speed to avoid cavitations. It is available in Type RDRN.
The advantages of Rotary Gear Pump with Modified Tooth Profile are as follows:
