These systems are mainly used for increasing line pressure of the supply line to obtain more water whenever the supply pressure is insufficient to fulfil the water needs of a society or row houses or tenements. These systems are self START/STOP systems and require no manual intervention.
These systems include the following components:
- 1. A Self-priming water pump which is the driver of the system. This pump can be-
single or three phase depending on the availability of power supply at the site
Single or Multistage depending on the delivery head to which the water is to be supplied
Regular or High Discharge models depending on the Flow or Volume of water required
The pipe size of the supply line
- 2. Control Panel – it incorporates the following features:
Auto START/STOP depending on the presence of water in the line
Single phasing protection for 3 phase pumps
3. Interconnecting cables between the pump and the control panel.
