Description
hw wisperflex – pressure boosting for reverse osmosis units
The hw wisperflex supports consistent reverse osmosis performance.
The booster pump is designed for continuous operation and runs smoothly without disturbing high-frequency vibration. Its intended operating pressure is 6 to 7 bar; it is factory-set to 6 bar. Its noise level is comparable to that of a running desk fan.
The hw wisperflex is designed for reverse osmosis units producing 100 to 700 litres per day at a permeate-to-concentrate ratio of 1:3.5. Increase the operating pressure to a maximum of 8 bar only within the permitted pressure limits of all connected components and in accordance with the equipment instructions.
A fine filter rated at a maximum of 10 µm must be installed upstream. The pump is intended exclusively for water of drinking-water quality. It is not suitable for heavily contaminated wastewater or service water.
