Hyjet Pump – 370W with Poly Change Over Device


The HYJET HHR Series is an automatic Rain / Mains changeover pump system with a mains pressure of 200 kPa, allowing tank water to be used for water supply in preference to mains water.

This pump has a quality proven electronic pressure controller that automatically starts the pump when there is demand for water supply. The pressure controller will only operate the pump if tank water is available.

The HHR pumps will automatically switch to mains water when tank water is empty and in case of power failure. In-tank float switches are not required making the system quick and easy to install.
