The super suction pump

The Pump unit

The salarollpump delivers ”super suction” performance thanks to a unique patented design feature.

The system is a peristaltic type of suction and pressure pump that delivers a flow rate of 9 m³/h, (39 gpm) or 14 m³/h, (61 gpm) depending on the size of the pump.



The heart of the system is a special manufactured hose compressed by a wheel mounted on a crank shaft. The suction is created when the hose by its own force returns to its round shape.

Discharge pressure is created by the force of the wheel moving the media. The high vacuum and the low speed of the pump enable it to pump most high viscous, polluted liquids and debris over 40mm, (1 1/2") solid. Both the pressure wheel and the inside of the pump housing have a lining of soft material that prevents a solid particle from damaging the pump hose.




The power pack for the salarollpump is available with a gasoline/diesel engine or electric motor which drives a hydraulic pump.

This powers the hydraulic motor mounted on the salarollpump. Pumping high viscous media is made easier by reducing the speed of the pump. The pump speed can be regulated by adjusting the hydraulic oil flow to three different output speeds, 15, 30 and 45 rpm. The power pack has two levers and a position label that are used to set the hydraulic oil flow to one of three different values.

The discharge pressure is not affected because the motor or engine is at full power. Additional fine adjustments to the pump speed can be accomplished by setting the throttle on the gas/ diesel engine.


Pumping extremely high viscous media is made easier by injecting water into the suction nozzle. The water reduces the friction between the oil and hose. A small centrifugal pump mounted to a backpack is offered as an accessory.
