Water pumps — bulk supply in Lahore

A water pump is one of the most-used machines in a Lahore house. It lifts water from the underground tank or main line to the overhead tank, and in many homes boosts pressure to bathrooms. Contractors and builders buying for several units, and owners building a new house, should match each pump to its job rather than buying the biggest one available.

Types and specifications

Key specifications on the nameplate:

• Power in horsepower (HP) or kilowatts (kW)
• Head: the height the pump can lift water
• Flow: litres per minute or hour
• Voltage and phase: single phase for most houses, three phase for larger pumps
• Inlet and outlet sizes

What each is used for

• Overhead tank filling: a centrifugal or peripheral pump sized to the height of your roof tank plus pipe losses
• Shower pressure on upper floors: a pressure booster on the outlet side of the overhead tank or a pressurised system
• Borewell: a submersible pump sized to the water depth
• Basement and site dewatering: a sewage or dewatering pump

Ask your plumber or engineer to work out the head and flow you need. Oversized pumps waste electricity and can damage fittings.

Quality checks on delivery

1. Nameplate: model, power, head, flow, voltage and serial number match the invoice.
2. Sealed box with warranty card and manual.
3. Shaft turns freely by hand (with power off).
4. No cracks in the casing or damaged threads on inlet and outlet.
5. Cable and plug condition for submersibles; cable length as ordered.
6. Serial numbers recorded on the invoice for warranty.

How much you need

Usually one lifting pump per overhead tank, and one booster per pressure zone. For borewells, one submersible per bore. For a multi-unit project, list each building's tank height, bathroom count and floors, and ask the supplier and plumber to size pumps per unit. There is no per-square-foot rule.

Bulk-buying tips

• Ask for a written sizing sheet for each pump.
• Buy matching controllers, dry-run protection and float switches together.
• Confirm warranty terms in writing: who handles claims, where and how fast.
• Pay after checking nameplates and serial numbers.
• Storage: dry, covered place, in original boxes until installation.
• Installation: mount on a level base, add a non-return valve and a strainer on suction lines, protect from rain, and use correctly rated cable and breaker.

What affects the price

• Pump type and power
• Head and flow rating
• Single or three phase
• Motor winding and build materials (copper winding, stainless or cast iron body)
• Controllers and pressure tanks
• Warranty length and service network
• Order size

We do not publish rates. Get written quotes for the same type, power, head and flow.

FAQs

What size pump do I need for my overhead tank? It depends on the height of the tank, the pipe size and length, and how fast you want it filled. Your plumber can calculate the head needed.

Is a pressure pump worth it? If upper-floor showers are weak, a booster pump usually solves it. Check that your pipes and fittings are rated for the pressure.

Can I run a water pump on solar? Yes. Solar pumps or a pump connected to a home solar system can run in daylight. Ask a solar installer about inverter compatibility.

Why does my pump trip or overheat? Common causes are dry running, wrong sizing, low voltage or a blocked suction line. Add dry-run protection and a stabiliser if voltage is low.
