TIANJIN HARVEST HIGH PRESSURE PUMP MANUFACTURING Co.,Ltd GPB-500 High Pressure Plunger Pump IlflRYGST TIANJIN HARVEST HIGH PRESSURE PUMP MANUFACTURING Co.,Ltd pressures 1-65MPa *The pressure and flow can be selected according to the actual working conditions of the user, and the specific pressure value and the range of the controllable area can be determined. The GPB-90 high-pressure jet grouting pump is a commonly used high-pressure slurry power equipment for high-pressure jet grouting pumps. It is suitable for strengthening, reinforcing and enhancing the soft foundations of new buildings, highways, high-speed railways, subways, etc., rectifying the uneven settlement of old buildings, the anti-seepage curtains of reservoir dams and underground construction projects, retaining soil cofferdams, mine leakage blocking, shaft lining protection, slope anchoring, etc. It can also be used for assisting in rock breaking and coal caving with high-pressure water jets, supplying liquid for underground hydraulic supports, pumping high-pressure water for hydraulic expansion metal bolts used in anchoring, dredging and cleaning large underground pipelines, serving as chemical pumps, and in the fields where high-pressure liquids are required as power, such as high-pressure water jet through holes. The GPB-90 high-pressure jet grouting pump is a new type of grouting pump that is lightweight, specialized, capable of high pressure, and can operate with a fixed (variable) quantity. It can pump both clean water and liquids containing solid particles or with a certain viscosity, as well as high-density polymer slurries. Features: 1. The crankshaft and connecting rod at the power end adopt a newly developed special bearing bush structure with high strength, high lubricity and a small friction coefficient. The transmission is balanced, the temperature of the power end is reduced, and it is more suitable for long-term continuous operation. 2. The safety valve adopts a diaphragm type, which will rupture when the pressure exceeds the limit. It is simple, safe and reliable. The GPB-500 series high-pressure plunger grouting pump is a new type of high-pressure grouting pump launched by our company. It is lightweight (with a total weight of 2800 kg), high-pressure, specialized, and can operate with a fixed (variable) quantity. It can pump not only clean water but also liquids containing solid particles, liquids with a certain viscosity, and high-density polymer slurries. Features: The power end of the pump adopts mature technology. The gear transmission reduction in the crankcase is in the form of double-helical gears, which has a large transmission torque, stable transmission, and low noise. A special bearing bush structure with high strength, high wear resistance, high lubricity, and a small friction coefficient is adopted between the crankshaft and the connecting rod. The temperature of the power end is reduced, making it more suitable for long-term continuous operation. The safety valve adopts a diaphragm type, which will rupture when the pressure exceeds the limit, and it is simple, safe, and reliable. The hydraulic end of the pump is an integral pump head. However, when replacing the plunger, seals, etc., there is no need to disassemble the pump head, which is more convenient, time-saving, and labor-saving. It is suitable for strengthening, reinforcing, and enhancing the soft foundations of new buildings, highways, high-speed railways, subways, etc., rectifying the uneven settlement of old buildings, the anti-seepage curtains of reservoir dams and underground construction projects, retaining soil cofferdams, mine leakage blocking, shaft lining protection, slope anchoring, etc. It can also be used for assisting in rock breaking and coal caving with high-pressure water jets, supplying liquid for underground hydraulic supports, pumping high-pressure water for hydraulic expansion metal bolts used in anchoring, dredging and cleaning large underground pipelines, serving as chemical pumps, and in the fields where high-pressure liquids are required as power, such as high-pressure water jet through holes. iEift r/min i£M weight: 1500kg /fell 200kg jfiy&n 2 " HARVEST High Pressure Pump 36
