Buying Guides
Start with the Most Common Pump Buying Questions
Six practical guides for importers, distributors and project buyers, covering pump selection, type comparison, total dynamic head, wastewater duty, borehole sizing and OEM ordering. Each guide is published here as a full article.

How to Choose a Water Pump: Start with the Water, Then the Duty Point
“I need a one-horsepower pump” is a common starting point, but it is rarely enough to choose one. Two pumps with the same motor power can deliver very different flow at the pressure your installation actually needs.

Peripheral vs Centrifugal vs Jet Pump: Which One Fits Your Job?
These three pump types often appear in the same clean-water catalogue, but they are not interchangeable just because the motor labels show the same horsepower.

How to Calculate Total Dynamic Head for a Water Pump
A roof 40 metres above the water does not automatically mean a 40-metre pump. Water also loses pressure through pipe, bends, valves and fittings, so total dynamic head adds those losses to the elevation change.

Drainage Pump vs Sewage Pump: Start with What Is in the Water
A flooded basement, a rainwater pit and a sewage sump can all need a submersible pump, but the water in them is not the same. Choosing on horsepower alone can lead to clogging or excessive wear.

How to Select a Deep Well Pump for a Borehole
“The borehole is 80 metres deep” does not mean you need a pump that delivers 80 metres of head. Borehole depth, pumping water level and outlet elevation are three different measurements.

Water Pump OEM Buying Checklist for Importers
A photo and a single price can hide different motors, plugs, cartons and accessories. A comparable OEM quotation needs the same specification on both sides of the table.

What to Confirm Before You Request a Pump Quote
Four points cover most of the information we need to recommend a model and quote a realistic price. Send them with your enquiry and the reply is usually faster and closer to what you actually need.
- Which pump category fits the application: household supply, irrigation, drainage, sewage, deep well, or pressure boosting?
- What flow, head, pressure, voltage, frequency, and installation conditions should be confirmed before quotation?
- Which OEM details matter for distributors: brand label, color, carton, plug, cable, spare parts, and accessories?
- How can buyers compare traditional booster pumps with smart constant pressure pump options?
