PUMPS & MOTORS

Keep your water systems moving.

Mechanical and electrical support for chilled-water and condenser-water pumps and associated motors.

01 / UNDERSTAND THE SYSTEM

Pumps & motors in context.

Pumps circulate water through chillers, coils and heat-rejection equipment. Noise, vibration, leakage or unstable flow can point to mechanical, hydraulic or electrical issues.

Noise and vibration are symptoms. Bearing condition, alignment, hydraulic duty and the motor all deserve attention.

Pump assembly

The casing, impeller, shaft, bearings and seals each have a role in circulation and containment.

Motor & coupling

Motor condition, alignment and the connection to the pump affect mechanical performance.

Drive & operating duty

Where installed, a variable-speed drive changes motor speed. Settings should match the pump and system requirements.

02 / SCOPE & CONDITION

What we look at.

Area	What matters	Why it matters
Noise or vibration	Bearings, alignment, mounting and hydraulic conditions	Replacing bearings alone may not address the underlying cause.
Leakage	Seal, gasket and joint condition	Identify the leakage point before deciding which materials to replace.
Low or unstable flow	System resistance, valves, strainers and controls	Pump condition is only one part of the diagnosis.

Work that can be included

Pump and motor condition assessment
Bearing, seal and gasket replacement
Motor repair and workshop coordination
Reassembly, alignment and operational checks

Define the scope before work starts.

Parts, quantities, access, shutdowns and reinstatement are confirmed against your site and equipment. Additional defects or specialist works are discussed separately.

03 / HOW THE WORK PROGRESSES

A clear route from enquiry to completion.

01
Inspect & identify
Record exact equipment and component details.
02
Plan the shutdown
Agree isolation, dismantling access and reinstatement.
03
Repair & reassemble
Replace confirmed parts and complete agreed mechanical work.
04
Align & check
Verify relevant alignment, leakage and operating observations.

04 / COMMON QUESTIONS

A little more clarity.

Can bearing size be confirmed from motor power?

No. Bearing selection must be verified from the existing bearing, exact equipment documentation or inspection. Motor and pump bearings can be different.

Can pump bearing size be selected from motor kW?

No. Confirm the bearing from the original component or exact equipment documentation. Pump and motor bearings may differ.

Should gaskets and seals be included?

Any disturbed sealing components should be assessed. The quantity and type depend on the actual assembly and dismantling scope.
