Explanation of Hydrascan^®

The HS series booster and the Hydrascan^®, are no longer available from Davey USA. Pumps already fitted with a Hydrascan^®, can be refitted with a Torrium ^®, controller. Please call Davey USA for details. For information on the latest in control technology, see the BT models with Torrium® control.

Hydrascan^® is Davey`s own unique constant pressure control unit. Hydrascan^®keeps the pump running whenever there is a demand for water, unlike the annoying 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. Hydrascan`s unique solid state flow sensing has no moving parts to obstruct pump performance or to become jammed with sand or grit.
