What are Submersible Pumps?
Submersible pumps are fully self-contained, sealed pumps perfect for any application where the pump needs to be completely submerged in liquid. Most commonly used for the transfer of stormwater, wastewater, greywater, raw or treated sewage, sand slurry, and the like. These pumps are typically centrifugal pumps and can be fitted with a cutter, grinder or agitator to assist with the pumping of solids. General Pump Company also specialises in helical rotor submersible pumps such as the Ultraflow UMHPD / UHAPD series.
Depending on the type, a submersible pump can transfer a variety of liquids, such as:
Black Water l Grey Water l Raw Sewage l Trade Waste l Stormwater l Subsoil Water l Rainwater l Bore Water l Food Stuffs l Chemicals
There are many different types of impellers used in submersible pumps including open & closed centrifugal impellers, vortex, axial flow, turbine, single channel, cutter, grinder, helical rotor, chokeless, non-clogging. With many different options, the right impeller can be selected for the type of liquid being pumped.
General Pump Company stocks a huge range of submersible pumps, including Sewage Cutter, Sewage Grinder, Positive Displacement Grinder, Drainage, Large Drainage, Heavy Duty Dewatering, Vortex, Axial Flow, All Stainless Steel and more. With so many different types to select from, we are sure to have the right submersible pump for you.

Working Principles
Submersible pumps are widely used in various applications, with different types designed to handle specific conditions and requirements. The operating principles of the main types of submersible pumps are as follows:
Multistage Centrifugal Submersible Pumps
- Vertical Operation: Use an impeller to accelerate liquids and a diffuser to convert kinetic energy to pressure energy, ideal for high pressure, low flow needs.
Horizontal Submersible Pumps
- Hydraulic Motor: Operates with a hydraulic motor and can have either: Closed cycle where power fluid is kept seperate from the produced fluid or Open cycle where Power fluid mixes with the produced fluid and is separated at the surface.
Screw-Type Submersible Pumps
- Steel Screw Mechanism: Efficiently handles water with high sand content and other impurities, suitable for abrasive environments.
Each type of submersible pump is designed to address specific operational challenges, whether it’s achieving high pressure with centrifugal pumps, utilizing hydraulic power in horizontal pumps, or handling abrasive fluids with screw-type pumps. The choice of pump depends on the particular requirements of the application, including the type of fluid, the presence of impurities, and the desired flow and pressure characteristics.
Features
- Fully Submersible Design: Operates underwater, making them ideal for dewatering, drainage, and sewage applications.
- Seal Protection: Equipped with robust seals to prevent water ingress into the motor and other critical components.
- Variety of Types: Includes multistage centrifugal pumps, screw-type pumps, and horizontal submersible pumps, each designed for specific needs.
- Compact and Portable: Their compact design allows for easy installation and transportation.
- High Efficiency: Designed to be energy efficient, reducing operational costs.
- Corrosion and Abrasion Resistance: Built with materials that resist corrosion and wear, suitable for harsh environments.
- Versatile Power Options: Available with electric motors or hydraulic motors, depending on the application.
Benefits
- Effective in Deep Water: Capable of operating at significant depths, making them ideal for well pumping and underwater applications.
- Space-Saving: Their submerged operation saves surface space, useful in confined or urban areas.
- Quiet Operation: Submersible design reduces noise, making them suitable for residential and commercial areas.
- Reduced Cavitation: Operating underwater eliminates the risk of cavitation, which can damage pumps.
- Minimal Maintenance: Durable design requires less frequent maintenance and reduces downtime.
- Versatile Applications: Suitable for a wide range of applications, including irrigation, sewage pumping, water supply, and industrial uses.
- Reliable Performance: Designed to handle various fluids, including those with high solid content, ensuring consistent performance.
