Quadruplex Constant Pressure with Variable Frequency Drives
Energy Saving Water Supply System
For domestic water supply designed to operate with optimum power consumption thus resulting in lower cost of operation compared to conventional pumps.
Date
Operating for more than ten (10) years.
Domestic Water Distribution
Supplies domestic water to a residential community.
The pump distribution system consists of four (4) vertical inline centrifugal pumps arrange for parallel operation. It supplies the water requirement for a residential compound with several buildings spread out in a gated community. The number of pumps operating at any time is managed by a programmable controller and the speed of the pumps is determined by the variable frequency drives. The system operates in full automation mode, free from human intervention. In case of emergency or fault in the system, the programmable controller determines what course of action to take. When normal condition is restored, the system starts each pump chronologically to prevent power surge and water hammer in the system.
