These Systems are Used for transfer of water from underground to overhead tank in residential, commercial, and industrial complexes, sometimes in absence of the overhead tanks, Diaphragm pressure tanks accompanied by pressure switches are used which ensure constant force of water at each every outlet.
These systems use following type of pumps for water transfer depending on the availability of space and overhead tanks:-
- Submersible Borewell Pumps To be Installed in an inclied manner
- Centrifugal Monoblocks or Coupled sets for high head/discharge applications
- vertical Inline Multistage Pump
These Systems Consist Of Following Components
- The Pump Which is the heart of the system
- Mounting Stand or skid depending on the type of pump
- Control Panel With level sensors to avoid manual intervention they are fitted with all possible protections to ensure trouble-free operation of the pump for prolonged periods of time
- Diaphragm tank, pressure switches, pressure gauge and different type of valves for a pressurized system
Normally these systems have 1 or 2 working and 1 standby pump, When there are 2 working pumps the first pumps start at a higher pressure. Even then if the pressure reaches the cut-off level and both pumps are tripped off. This helps in conserving energy.
The control panel is also designed such that all 3 pumps (2W+1S) start sequentially in a cascade operation so that none of them get jammed due to lying idle for a long time.
Applications:
- Residential Societies
- Industrial Complex
- Shopping Malls
- Commercial Office Building
