Advantages
1. Parameter High: Rated high pressure, high speed, large power-driven pump
2. Efficiency, volumetric efficiency is 95% of the total efficiency of about 90%
3. Long life
4. Variable convenient form for
5 More unit power and light weight
6. Piston main components are compressive stress, strength of materials can be fully utilized
7. Piston pumps have a wide pressure range, can reach high pressures and the pressure can be controlled without an impact on the rate of flow. Piston pumps have a continuous rate of discharge. Pressure changes and discharge rate have minimal effect on performance. Piston pumps can maneuver viscous fluids, high gas volumes and solids, only if the valves are correctly designed.
Disadvantages
• Piston pumps cost more per unit to run compared to centrifugal and roller pumps. The mechanical parts are prone to wear, so the maintenance costs can be high. The valves must be resistant to abrasives for large solids to pass through. Piston pumps are heavy due to their large size and the weight of the crankshaft that drives the pump.
Applications
• Mobile equipment
• Marine auxiliary power
• Construction equipment
• Oil field equipment
• Machine tools
• Metal forming and stamping
• Packaging machinery
