A special branch was looking for a reliable, solids-resistant mobile pump for combating oil-based contamination in the fight against sea pollution. The pump needed to be used to remove oil spills from the sea in coastal areas. They were looking for a pump which could also be used in clean-up operations as a transfer pump for discharging portable tanks or other collection tanks. The pump needed to convey the oil over long stretches to tanker vehicles or suction tankers. Several types of pump were tested. Hose pumps, membrane pumps and eccentric screw pumps were all considered for their purposes. However not one of these pumps were suitable for the application. The hose pump had persistent problems with excess wear and damage to the hose unit, the membrane pump had constant faults in the ball valves and the design of the eccentric screw pump was not suitable for mobile use. The customer chose a Boerger Rotary Lobe Pump.
The Boerger Rotary Lobe Pumps are ideal for this type of application. In addition to the compact and space-saving design, the customer was particularly impressed with its resistance to solids, the robust design and the proven high reliability of the Boerger pumps. A special vehicle with chain drive was used for the mobile pump unit. The Boerger pump was driven by diesel motor. This means it can be used in any location.
