GPB-500 high pressure slurry pump is a light weight (total weight 2800KG), high pressure, special use, quantitative (variable) new high pressure injection pump developed by our company that can pump clear water, solid particles or liquid have a certain viscosity and also high density polymer paste. Characteristics: The power end of this pump is based on mature technology. Crankcase gear transmission is decelerated into a spiral herringbone gear with large transmission torque, stable transmission and low noise. A special bearing structure with high strength, high wear resistance, high lubricity and small friction coefficient is used between the crankshaft and the connecting rod. Low temperature rise of the power end is more suitable for long time continuous operation. The safety valve adopts diaphragm type, overpressure rupture, simple, safe and reliable. The pump liquid end is the integral pump head structure, but when replaces the plunger, seal parts etc. disassembling the pump head is not needed, thus it is more convenient, time-saving and labor-saving. It is suitable for reinforcement of weak foundations such as new buildings, expressways, high-speed railways and underground railways, uneven settlement of old buildings, anti-seepage curtain for reservoir dams and underground construction projects, and anchoring hydraulic expansion metal anchor pumps high-pressure water, underground large-scale pipeline dredging cleaning, chemical pumps, high-pressure water jets through holes or other areas powered by high-pressure liquid.
