The main structural feature of the reduction gearbox: A large-speed ratio reduction system is suspended on the side of the pump housing, ensuring smooth transmission and significantly reducing the weight of the pump. Main structural features of the hydraulic end: Three-cylinder integrated (separated) layout, the suction and discharge valve assembly can be disassembled and assembled independently, facilitating maintenance and repair, and having a long service life.<\/p>\n<p>Mud Pump: ZB250-36-90\/15<\/p>\n<p><strong><b>Main Technical Specifications<\/b><\/strong><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li>Performance data of Power end<\/li>\n<\/ul>\n<p>Max.
