Installation Sequence For Water Circulation Pumps

Transfer the circulation pumps units from the stores to the areas where they are to be installed as soon as the concrete foundation is ready and in the correct location as per approved layout drawings.

Hot water circulation pump pipework will be thermal insulated and cladding calls for pump bodies, air vents, drain valves and altitude gauge connections must be extended clear of the insulation thickness and finishes, manufacturer recommendation will also be considered.

Ensure pump location are arranged to provide access for periodic maintenance, including removal of motors, impellers, coupling, mechanical seals, etc.

Place the pump on the prepared area and align the pump as per piping layout discharge and suction approved shop drawing details and outlet delivery pipe work.

Acoustic & Anti-Vibration isolators/ neoprene pads will be installed on the base mounting as required for the Hot Water circulation Pumps as per manufacturer’s recommendations and the specification.

Ensure all isolation valves installed are square and plumb, allowing sufficient access during operation and maintenance.

Nuts, bolts and clamps are also to be checked to ensure proper tightness by using torque wrench.

Provide flexible connection for every individual pump between the pump and piping connection, make sure all flange connections are complete with gasket seals.

Connect the pipe work to the Hot water circulation pumps as indicated on the approved shop drawings.

Support the pipework adequately to ensure no additional load is borne by the Circulation pump, provide supports as per approved details and project specification.

Complete the termination of all electrical power connectors.

Ensure all cables & wire terminations are done by competent electricians having valid certifications only.

Make sure all BMS, interchange, control, and electrical power connectors have been installed and termination is done properly.

Alignment and testing of Hot water circulation pumps will be carried out by the specialist contractor/manufacturer, including Tools and instruments dial gauges with calibration certificate.

Pumps are mounted on the foundation as per manufacturer standards.

Make sure approved tagging/labeling is provided as per specification.

Cover the installed pumps with polyethylene sheets for protection against dust and minor damage as per approved IAQ plan.

Testing & Commissioning of Hot water circulation pumps shall be done as per the relevant approved method of statements.

Work Inspection Request (WIR) shall be submitted by Site Engineer to consultant for verification, inspection and approval.
