How to find the right high-pressure pump
- Define the duty point. Required flow in l/min and working pressure in bar. The flow of a positive-displacement pump depends only on its speed, the pressure on the resistance in the system.
- Choose the pump type. Plunger pumps for high pressures up to 690 bar and a wide choice of materials, piston pumps for pressures up to 105 bar with strong suction capability.
- Select the material for the fluid. Pump heads are available in brass, nickel-aluminium bronze, 304 and 316 stainless steel and duplex. The right one depends on the fluid, its temperature and the water quality.
