For consistent, reliable water pressure where it matters most, the Walrus HQ200 Pressure Booster Pump delivers dependable performance across residential, commercial and light industrial applications. Designed to boost water pressure from underground tanks, rainwater harvesting systems or low-pressure mains, this complete all-in-one unit helps maintain a steady flow for showers, taps and irrigation systems.
The Walrus HQ200 integrates the pump, motor, pressure tank and electronic controller into one compact package — meaning automatic operation that starts when water is drawn and switches off when not needed. Built from high-quality corrosion-resistant materials, it offers quiet operation, energy-efficient performance and built-in protection features such as thermal overload and dry-run shut-off, helping extend service life and reduce maintenance.
Ideal for boosting water pressure in homes, gardens, irrigation systems and light commercial buildings, the HQ200 is engineered for straightforward installation and dependable use even where space is limited.
