The pump operation is controlled as per the chilled water or cooling requirements and sequence of operation is automated via field control devices i.e. valves, thermometers and pressure switches etc.
Pump sets are supplied mounted on a substantial fabricated base plate; the complete assembly is of a rigid construction, being intended for mounting on suitable foundations.
The pump sets are supplied fitted with a proprietary high efficiency electric motor adequately sized for the duty specified.
Below is a sample checklist which can be used for inspection of pre commissioning of pumps.
A complete method statement for testing and commissioning is available on our website.
