Positive Displacement Pumps

The Sliding Shoe pump is unique to all other pumps in the world and offers the advantages of many different pump types in one pump. No other pump has as many unique design features and benefits.

The Megator self priming positive displacement sliding-shoe pump provides exceptional suction performance, versatility, and the ability to pump at constant capacity against heads to 250′ (76m). It can run without harm during dry suction, is self compensating for wear, has a simple design with few working parts and single cover access to its wear parts. It might be said to resemble a reciprocating piston pump, and it has indeed all the well known merits of that type – powerful suction and self priming, constant capacity at varying heads, the ability to cope with rough conditions and to handle a great variety of liquids, viscous or free flowing, clean or dirty. Yet in its simplicity, compactness and smooth flow it more closely resembles the centrifugal pump. It therefore combines the advantageous features of both these two main pump types without their respective limitations.

Oil & Pollution Recovery

Ideally suited for pollution recovery duties, Megator pumps are normally supplied as portable sets mounted in a lightweight tubular frame with wheels, but are readily available for static installations. The prime mover may be a gasoline or diesel engine or TEFC electric motor.

The low shear effect of the sliding shoe pump prevents oil from emulsifying. Combined with self-priming, super-suction, dry running capabilities and the ability to pump air and water with a smooth continuous non pulsating flow make it ideal for offloading skimmers.

They will handle clean or dirty oils of low or high viscosity, any mixture of oil and water, any amount of air without loss of prime and are ideal for use with the Megator range of oil recovery skimmers. Providing an efficient method for removing oil, effluent, sewage scum and various other nuisance liquids from the surface of water.
