1.The BW250 type grouting pump is horizontal three cylinder reciprocating single acting piston pump.
2.The pump has two cylinder and four speed. Large diameter (up to 80mm) for 1000 meters of large diameter drilling equipment, lack of small diameter (up to 3.65mm) for 1500 meters of small diameter drilling equipment.
4.Two short diameter has four gear displacement.
5.For different aperture deep use (due to the limited number of traffic block, still retains three adjusting mechanism for traffic).
6.In this way, to meet the basic rig in washing liquid on the reduction of three pass back to the water, thus reducing fluid three wear and power 5 consumption.
7.Because of the four gears in the pump body. The structure of the utility model has the advantages of small size, small weight and good decomposition property, and is convenient for carrying in the mountain area. The utility model not only can supply water, but also can send strong mud, so the utility model is suitable for geological exploration
