General: Drilling processes can be marked as a ‘non stop’ chain process. Every step in the process of making concrete, to drilling, injecting and transport the concrete overflow must be well prepared. Every small chain in this process which fails, stops the complete drilling process. Reliability, wear resistant are features which belongs to the BBA heavy duty sludge pumps. For pumping high abrasive fluids with large particles, the so called “miracle pump” of the NB series has proven itself. Big well-known contractors all over the world have switched to this type of sludge pump in the so called “HDI application”. Quick self priming over long suction lines, no extra booster pump necessary and suitable for media with densities up to 1,8 kg/dm3, results in no better pump solution. The NB 140 (6”) series are equipped with a 120 m3/h vacuum diaphragm pump. The centrifugal pump has a free passage of 105 mm and has a maximum flow of 350 m3/h.The float box is equipped with quick release couplings for easy cleaning after a drilling shift. Applications: This dry prime centrifugal pump system is used for pumping bentonite, drilling sludge, emptying excavations and as a robust rental pump.
