Selfpriming Centrifugal Pump 'RSC'


Rovar RSC pumps are self-priming centrifugal pumps suitable for handling clear, liquid contains solids in suspension, contaminated and low-viscosity liquids. The innovative design, eliminating the need for a non-return valve, results in less maintenance. The self-priming ability prevents the pump from running dry and ensures smooth and easy operation.

Working principles

The self-priming operation of the RSC series is based on the injection principle. While starting, the pump sucks the air in the suction pipe and drawn into the pump, with the air and liquid mixture being compressed in the pump. This mixture flows to the top of the pump casing where the air separates from the liquid and is removed through the discharge pipe. The liquid keeps recirculates in the pump casing until all air is evacuated from the suction pipe. The pump functions thereafter as a conventional centrifugal pump. Before first start-up, the pump casing must be filled once with liquid. The special design prevents the pump from emptying after it has stopped pumping. In that way, there is enough liquid in the pump for the next start-up.

Selfpriming Centrifugal Pump 'RSC'


Self priming, without foot valve up to 7 m depth.

Pumps liquids, solids, emulsion, aerated liquids, viscosity max of 110 cSt.

Pump can be installed well outside/above the liquid, thereby easy for operation, service & inspection.

Externally lubricated Mechanical seal for trouble free life & can run dry.

Various material options like cast iron, stainless steel, and bronze.

Electric motor, diesel engine, air motor, Hydraulic motors can be used as the prime mover.

Suitable for a maximum pump speed of 3700 rpm approx.
