Walrus HQ400 booster pump
The HQ is a complete, all-in-one unit, consisting of a pump, motor, pressure tank, and electronic controller. The built-in electronic controller provides constant pressure which ensures that the pump starts automatically when water is consumed and operates continuously until water is not required.
The compact design and quiet operation make the HQ series suitable for many applications. The HQ is constructed from top quality corrosion resistant materials. The pump has a built in dry-run shut-off and automatic reset function. The motor has a built-in thermal overload to protect against high operating temperatures and over current.
The HQ has an anti-cycling feature which prevents the pump from continuously starting and stopping when you have a dripping tap or minor leak in the system. The pumps will lift water up to 7.6m. with foot valve and pump suction piping filled with water.
