2 APPLICATION. Domestic : High-rise buildings, Condominiums, Apartments etc. 2. Commercial : Office buildings, Hotel, Shopping centres etc. 3. Industrial : High-rise factory, Manufacturing & processing industries applications etc. 4. Social service : School, Hospitals etc. FEATURES. 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 prevent frequent start and stop of pumps, requires small hydropneumatic 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. CONTROL SYSTEM 6 Q Flow switch 5 4 P3 3 P Parallel Operation 2 P2 Single Operation Qapacity Step ) Both pumps are stopped when water tank is fully charged. In this condition water is supplied from the tank and water in tank gradually decreases. Step 2) No. pump start at P (point ) and water supplied from pump and tank. Step 3) When more water is required and water decreases to P2 (point 2), no. 2 pump also starts, operation point shifts to point 3 and system shifts to parallel operation. Step 4) When water consumption decreases, water in tank increase and when reaches P3 (point 4) no. 2 pump is stopped and operation point shifts to point 5. Step 5) When water consumption further decreases, water in tank increases and switch is turned off and the flow switch used to detect small flow is turned off. When both and flow switch are off, no. pump stops (point 6). Flow switch setting point is at small capacity point; therefore pump continuous operation range is much wider. Accordingly pump start frequency is greatly decreased.
