High-pressure plug piston pump for petroleum, chemical, fertilizer industry as a process pump, metallurgy, rolling mills, high pressure water descaling, construction, shipbuilding, sugar, paper, chemical and other industries of high pressure water cleaning descaling, oil field water injection, boilers Water supply, the power source of hydraulic machinery, as well as food, pharmaceutical and other parts of the need to produce high-pressure liquid, the transmission medium is fluid without solid particles. High-pressure piston pump, including high-pressure three-piston pump, the pump is all horizontal, it is more stable than the vertical, small vibration, assembly and disassembly, easy maintenance. Also known as three-cylinder pump, with a uniform flow, pressure pulsation is also reduced accordingly. Model serial number is: 3p00 3p10 3p20 3p30 3p40
