1. It has four flow rates to meet the needs of both large and small diameter drilling rigs, with a wide flow adjustment range and reasonable parameter selection. It can be used with XY-4 and XY-5 core drilling rigs. It can meet the needs of core drilling of different diameters, hole depths, and geological conditions.
2. The piston is a self-sealing S-type polyurethane rubber piston with a bowl shape and nylon backing, greatly improving its service life.
3. The connecting rod is equipped with five dustproof sealing rings to prevent mud from the hydraulic end from entering the power end and the power end lubricating oil filter. Multiple production tests have proven its reliable sealing and excellent performance, extending the service life of the gears.
4. The inlet and outlet valves use steel balls, and a sound-dampening rubber pad is installed on the valve cover to reduce impact noise.
5. The pressure gauge uses a BY-1 type anti-vibration pressure gauge with a long service life.
6. Compact structure and beautiful appearance.
