Oil spills happen from time to time. to prevent incidents, the emergency services and fire brigades have decontamination units. Depending on the size, they can decontaminate 40,000 to 160,000 litres of oil-water mixture in one hour. each unit contains three Accuvon Rotary Lobe Pumps. An AP140 self-priming mobile feed pump conveys the contaminated fluid to the unit, the pump is mounted in a Euro-box size frame and is selected to operate with inverter speed control, and there are two additional pumps in the container, also inverter controlled. After mechanical separation of the oil from the water, the separated high viscosity oil is pumped by another AP140 to a tanker truck, the separated water is returned to the river/drain or to the inlet of the separator if it still contains traces of oil, The customer chose Accuvon rotary lobe pumps because they require little space, operate with low shear effect and are perfectly flow controllable.

High-viscosity sludge needs to be removed from a tar lake. Previously installed pumping systems failed due to the high viscosity - up to 50,000 mPas depending on the temperature - and the relatively large solids content. Both factors caused the previous pumps to clog and block. The solution for this application was the Accuvon double pack, consisting of a HAP 80 Multicrusher and an AP 80 Rotary Lobe Pump, mounted on a common frame but driven individually by hydraulic motors. The complete submersible unit is explosion-proof and complies with the European ATEX standard.

Occasional oil spills occur. To prevent such incidents, the emergency services and fire brigades have decontamination units. Depending on the size, they can decontaminate 40,000 to 160,000 litres of oil-water mixture in one hour. each unit contains three Accuvon rotary lobe pumps. An AP 100 self-priming mobile transfer pump delivers the contaminated fluid to the unit. The pump is mounted in a Euro-box size frame and is speed controlled by an inverter. two additional pumps, also inverter controlled, are located in the container. After mechanical separation of the oil from the water, the separated high viscosity oil is pumped by another AP100 to a road tanker. The separated water is returned to the river/drain or, if it still contains traces of oil, to the inlet of the separator. The customer chose Accuvon rotary lobe pumps because of their small footprint, low shear effect and perfect flow control.

A typical pneumatic pumping station operates with a combination of pneumatic system and rotary lobe pumps. The suction side of the rotary lobe pumps is designed to prevent solids (i.e. stones, gravel) from entering the pump. The pumps handle only the wastewater. Stones and other particles will fall into the vessels of the pneumatic system. While the pumps are handling the main volume of sewage, the pneumatic system is used twice a day to push the solids out of the system and also to clean the pipe system of sediment. A combination of valves isolates the two systems. Both systems are operated automatically via a PLC control panel!
