The Davey multistage pressure boosting system is controlled by the Hydrascan
controls which
provides consistent and high-pressure water flow. The Hydrascan control
starts the pump as soon as you switch on the tap and runs continuously until
no water is needed. A strong and even flow can be achieved
improving the performance of showers, faucets and irrigation systems. Compact, quiet and
easy to install this system can meet all residential needs including existing well systems.

Operating Parameters |

Hydrascan is a unique control pressure unit. This unit keeps the pump running whenever there is a demand for water unlike the stop-start (cycling) of traditional pressure switches. Hydrascan incorporates an adjustable pressure sensor which starts the pump based on pressure, and a flow sensor which stops the pump based on flow. Hydrascan will stop the pump if the flow is reduced below 0.5 gallons per minute. Hydrascan protects your pump by switching it off if the water supply becomes inadequate. Its unique solid state flow sensing has no moving parts to obstruct pump performance or to become jammed with sand or grit. The ability to adjust cut-in pressure (from 20-80 psi) makes Hydrascan the ideal choice of controller for pressure systems that can be used in a range of different applications. |
