Step 1) Both pumps are stopped when water tank is fully charged. In this condition water is supplied from the pressure tank, and water pressure in tank gradually decreases.Step 2) No.1 pump starts at pressure P1 (Point ) and water is Supplied from pump (and pressure tank)
Step 3) When more water is required and water pressure decreases to P2(Point ), No.2 pump also starts, operation point shifts to Point
and system shifts to parallel operation
Step 4) When water consumption decreases, water pressure in tank increases and when pressure reaches P3 (Point ), No.2 pump is stopped and operation point shifts to point .
Step 5) When water consumption further decreases, water pressure in tank increases and pressure switch is turned off, and the flow switch used to detect small flow, is turned off. When both pressure and flow switches are off, No.1 pump stops (Point ). Flow switch setting point is at small capacity point, therefore pump continuous operation range is much wider. Accordingly pump start frequency is greatly decreased.
1. All components are integrated on a rugged steel base. It is ready for use by only connecting with supply piping and to the power source.2. Layout is very compact and much lighter than conventional units. It occupies lesser space and requires easier installation than conventional units.3. The flow control system which prevents frequent start and stop of pumps, requires only small hydro-pneumatic pressure tank and ensures
constant fresh water supply.4. Pumps are in parallel operation for high demand and alternating in low demand, suitable for energy saving.(Model UD2-D)5. Various options are available on request.
