Axial Piston High Pressure Pump HPS 0.6-1.0

Description

The HPS 0.6-1.0 SWRO high-pressure pumps are designed with two ports and are primarily intended for use in pump group systems. These pumps are not self-priming, meaning the inlet pressure must always remain positive. Failure to maintain positive inlet pressure will result in permanent damage to the pump.

To ensure proper operation, the simplest approach is to disconnect the pump’s inlet pipe and measure the flow. When the water tank’s liquid level is at its lowest, the water supply flow should be at least 20% greater than the pump’s delivery flow. This ensures that the inlet maintains positive pressure while the pump is running.

Do not install a filter between the pump and a direct water supply from the tank, unless a pressure switch is installed on the inlet pipe to prevent negative pressure from affecting the pump.

Electric Pump Set:

Use a standard bell housing and coupling to connect the pump to the B5 motor flange. The pump should not operate under axial or radial loads on the output shaft. Gear couplings are recommended whenever possible to avoid such loads.

Operating Temperature:

The HPS 0.6-1.0 SWRO high-pressure pumps are designed for use in temperatures between 2°C and 50°C for optimal performance. For temperatures below freezing, an environmentally friendly antifreeze is required. While the pump can also operate at temperatures above 50°C, doing so may reduce its volumetric efficiency. For higher operating temperatures, it is essential to specify the maximum temperature when ordering.

Filtration:

All water entering the pump should be pre-filtered to a nominal rating of 10 microns (with an absolute value of 25 microns). In closed-loop systems, backflow filtration is acceptable. High-pressure filtration is also an option but is generally considered more expensive.

Fluid Compatibility:

The standard version of the pump is compatible with drinking water and industrial water, such as distilled water, reverse osmosis water, or demineralized water. Depending on the specific operating conditions, modifications to sealing materials or construction may be necessary.

While the standard construction can handle seawater, prolonged exposure to seawater’s increased corrosive potential may require higher-grade materials for extended service life.
