The BBA sludge pump BV100-260 is the perfect solution for pumping drilling sludges. Thanks to the reliability, wear resistance and quick cleaning concept it is well prepared for the ‘non stop’ drilling processes. The BV 100 (4”) series is equipped with a 100 m3/h vacuum diaphragm pump, which makes the pump suitable for priming liquids with a densitiy up to 1,8 kg/dm3. The Enduroseal concept enables the mechanical seal running in an enlarged oil bath, suitable for continuous use, even in intermediate flow situations. A pressure relief chamber behind the mechanical seal prevents water entering the drive of the pump unit. The centrifugal pump has a free passage of 86 mm and has a maximum flow of 175 m3/h. The float box is equipped with quick release couplings for easy cleaning after a drilling shift.
After starting the unit, the vacuum pump starts priming air out of the suction line. A non-return valve shuts off the discharge side. As soon as the water is primed, the float closes the vacuum pump connection and the centrifugal pump starts pumping water.
This dry prime centrifugal pump system is used for pumping bentonite, drilling sludge, emptying excavations and as a robust rental pump.
