The main types of pump are centrifugal, submersible, gear, screw, diaphragm and slurry pumps, plus fire fighting pumps. The right type depends on the fluid, flow rate, head and whether you need high flow or high pressure.

A centrifugal pump is a pump that moves liquid by spinning an impeller, which throws the liquid outward and creates flow. It is the most common pump type for water, chemicals and low-viscosity fluids in industry.

A centrifugal pump works by using a rotating impeller that adds speed to the liquid, then a casing that converts that speed into pressure to push the fluid through the pipe. It gives high flow at low to medium pressure.

The main parts of a centrifugal pump are the impeller, casing, shaft, bearings, mechanical seal and the suction and discharge ports. The impeller is the part that actually moves the fluid.

A submersible pump is a pump that works fully submerged in the fluid, with a sealed motor that pushes water up from below rather than sucking it from above. It is ideal for borewell, sewage and dewatering applications, with a head up to 200 m.

A screw pump is a positive displacement pump that moves fluid using one or more rotating screws, giving a smooth, pulsation-free flow. This makes it ideal for thick, viscous and high-pressure fluids like oil.

A screw pump works by trapping fluid between the threads of rotating screws and the pump body, then pushing it steadily from suction to discharge as the screws turn. This creates a continuous, gentle flow.

A diaphragm pump is used for corrosive, abrasive and sensitive media, giving dry-run-safe, leak-free operation. It suits chemical, slurry and metering duty where other pumps would fail or leak.

A slurry pump is a heavy-duty centrifugal pump built to move abrasive, high-density mixtures of liquid and solids. With a high-chrome alloy or rubber-lined body, it is ideal for mining and mineral processing at flows up to 500 m³/hr.

A mechanical seal is a device that seals the gap between a rotating pump shaft and the pump casing to stop leakage. It uses two flat faces, one rotating and one fixed, pressed together to hold the fluid inside.

The main types of mechanical seal are single, double, cartridge and balanced or unbalanced seals. The right type depends on the pressure, the fluid and how much leakage protection is needed.

A pump mechanical seal usually fails from dry running, wrong installation, wear of the seal faces or a chemical attack on the seal material. Correct material choice and lubrication greatly extend seal life.

A jockey pump is a small pump that maintains steady pressure in a fire fighting line so the main pump does not start for small pressure drops. It keeps the system ready and protects the main pump from frequent starts.

An electric fire pump runs on mains power, while a diesel fire pump runs on its own engine and works even during a power failure. Many buildings use a diesel pump as a reliable backup.

Choosing the right pump depends on your fluid type, flow rate, head pressure, viscosity and installation location. Share these details with our team and our engineers will recommend the most suitable pump and system for your exact requirement.
