Industry Application
Pumps For Water Supply Drainage And Building Services
Municipal supply, high rise boosting, heating and cooling circulation, irrigation and fire fighting all run on the same family of end suction centrifugal pumps. The trick is picking the duty point rather than the biggest pump in the catalogue.
What Goes Wrong On This Duty
The pump is oversized and throttled
A pump chosen on a rule of thumb ends up running against a half closed valve, burning power and wearing the seal. Sizing on the real curve fixes it.
Upper floors lose pressure at peak
Supply pressure drops exactly when demand rises. A boosting set holds the duty point instead of cycling.
Plant room noise reaches the building
Direct coupled pumps with balanced impellers vibrate less, which matters when the plant room sits under occupied floors.
What Buyers Ask For
- A duty point the pump actually runs at, not a catalogue maximum
- Cast iron, stainless or bronze depending on the water quality
- Close coupled sets where the plant room is tight
- Motors for 380 to 415 V three phase at 50 or 60 Hz
- Spares that can be sourced years after commissioning
Recommended Equipment
Pumps That Cover Supply Drainage And Circulation
Horizontal sets for plant rooms with floor space, vertical inline sets where the pump goes straight into the pipe run.

Where The Equipment Sits
High Rise Boosting
Pressure increasing supply for tall buildings, where the pump has to hold head across a varying demand.
Heating And Chilled Water
Cold and warm water circulation matched to the circuit resistance rather than oversized for safety.
Irrigation And Transfer
Garden and field irrigation and long distance transfer where pipe losses dominate the head calculation.
How We Work
From Duty Point To Commissioned Set
Duty Point
You send flow, static lift and pipe losses. We check the curve and propose an impeller and motor rather than a frame size.
Material Choice
Water quality decides cast iron, stainless steel or bronze for casing and impeller, and mechanical seal or gland.
Works Test
The set is assembled and run on the test bay before painting and packing.
Commissioning Support
Installation and commissioning guidance, then spares held against the model number.
Delivery
What You Get With The Order
- Pump and motor supplied as a matched set for the stated duty
- Flanged connections sized from the caliber, up to 500 mm on the largest model
- Operation and maintenance manual with the commissioning steps
- Spare impellers, seals and bearings available against the model number
- Export packing and documentation through the Hong Kong office
Answers
Water Supply And Drainage FAQ
Can you supply a booster set rather than a single pump?
Tell us how many pumps, the control philosophy and whether a vessel is required. We quote the pumps and advise on the arrangement; the control panel is specified with the order.
Which pump suits a fire fighting duty?
Fire duty means holding a defined head at a defined flow with a certain starting arrangement. Send the required duty and the standard the installation follows, and we will confirm the model.
What is the largest flow you can cover?
The centrifugal range runs to 1500 m3/h with heads to 150 m and drives to 160 kW.
Do you supply pumps for seawater or brackish water?
Water chemistry decides the material. Send an analysis and we will confirm whether bronze, stainless or a different line is appropriate.
How long is the lead time?
It depends on the model and the motor. Lead time is confirmed on the quotation, and we do not promise a date before the motor supply is checked.

Send The Flow And The Head
With the static lift and the pipe losses we can size the impeller instead of guessing the frame.
