Sala Rollpump - High viscous pump

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 series of pump tests were conducted from October to December 2004 to measure the suction capability of the Sala roll pump with high viscous oil.

The tests were carried out with and without water injection in the suction nozzle.

The results indicate that the limit without water injection was approximately 3,500,000 cSt at shear rate 0.07 S^-1 .

With water injection the capacity was increased to approximately 65% of the nominal capacity at a viscosity around 4,500,000 cSt with the same shear rate of 0.07 S^-1.

High viscous pump: Suitable for pumping debris laden viscous oil

Sala clean up system for oil and chemicals is a unique patented system designed for rescue and clean up of oil spills and other high viscous and polluted liquids.
The extremely strong suction (vacuum) and the debris tolerance of 40mm, (1 1/2") solids make it suitable for pumping debris laden viscous oil. The extremely high discharge pressure makes it possible for liquids to flow through a long distance of hose. The combination of handling weight and portability enables the user to deploy the system in remote areas.

First and fore most, the Sala roll pump delivers "super suction" performance which it owes to a unique design. Sensible design also means sound performance. The Sala roll pump was developed for clean up of oil spills, chemicals and polluted liquids. It is also used for cleanup of oil spills from accidents that occur in the ocean, lakes, rivers and chemical spills from industrial plants, trucks, trains and airports. The combination of handling, weight and portability enables the user to deploy the system in remote areas.
Sala roll pump is unique because the pump is a peristaltic type of suction and pressure pump that delivers extremely high vacuum. This makes it possible to lift high viscous liquids from the ground such as bunker oil at temperatures around the freezing point.

The high discharge pressure makes it possible for liquids to flow through along distance of hose. No valves obstruct the free flow of pulp through the pump and 40 mm, (1 1/2”) solids can pass without damaging the pump. Lost protection gloves and other safety items which clog seals or cause damage can pass through the system without any problems. Should a blockage occur, the hydraulic drive system can be reversed to clear the pump. The Sala system can also pump corrosive chemicals such as ammonia, nitric, sulfuric acid, chlorine etc.

The Sala roll pump system can be used for chemical cleanup as no mechanical components will come in contact with the discharged media. The hose inside the pump housing is made of nitril which is resistant to many chemicals. Other hose material can be supplied on request.
Combination of high temperatures and aggressive chemicals may reduce the lifetime of the hose. It is recommended to replace the pumphose after a cleanup of aggressive chemicals.

Importantly, the Sala roll pump can handle temperatures of 100 degrees C (212 degrees F) and may increase to 130 degrees C (266 degrees F).
