Product Features:
1. Performance features: High-power, Large displacement, High pressure. Displacement and discharge pressure evenly. Small size and light weight. 2. Structural characters Drilling mud pump or pump unit adopts modular design, disassembly and moving easily. The full processing forged crankshafts have light unbalanced weight , running even, multi-point support and high strength characters. In order to reduces the eccentric wear of the partial cylinder liner, joint bearings are used between the crosshead and extension rod. The crosshead surface is sprayed babbit metal to improve allowable specific pressure and allowable speed. The new type hydraulic cylinder reduces its weight, improves suction performance and replaces the suction valve easily. The main pressure parts of fluid end all adopt alloy steel forgings. “No welding ,no casting” design improves their reliability. |
