This product is a manual hydraulic pump dedicated to mining construction machinery, serving as a portable hydraulic power source for equipment such as drills and crushers.The main pump body is cast from cast steel/aluminum alloy, and the valve group and transmission parts are forged from alloy steel and processed by precision machining, balancing structural strength and portability. The surface is treated with sand blasting and painting, galvanizing, oxidation, etc., which can resist dust and oil pollution at mining construction sites. The seals are made of oil-resistant rubber to ensure the sealing and pressure resistance of the hydraulic system. Equipped with an accurate pressure gauge and a convenient operating handle, the product has adjustable output pressure, suitable for light hydraulic operations such as hydraulic bolt fastening and cylinder jacking of mining equipment, and compatible with a variety of imported and domestic hydraulic tools.
