The AQUALIFE range of 5” submersible borehole pumps are compact and supplied as a complete pump and motor unit. This range offers a wide range of flow rates up to 13.2m³/hr and pressures up to 126m (12.6 Bar). These submersible multistage pumps are excellent at extracting water from thin and deep boreholes due to their compact design.


Each AQUALIFE pump is supplied with a 10m cable as standard and a control box with a built-in capacitor for ease of maintenance and operation (Single phase version).


This range is installed with a patented floating impeller design, this allows it to accept up to 300g/m³ of suspended sand content which is the highest on the market. It is also fitted with a suction guard that will block any unwanted solids entering the pump, this combined with the floating impeller almost eliminates abrasive wear.


This 5” borehole pump range is excellent at supplying ground water or boosting pressure to domestic, holiday and industrial properties, extracting water from wells and Roman wells, fire fighting and irrigation. Pumped fluids must be clean, thin, non-aggressive and compatible with the installed materials.

A borehole is a deep and narrow hole made in the ground, it is typically drilled to locate water or oil. A borehole pump is placed down the hole and submerged in the water, they are used to extract water for agriculture, pressure boosting, irrigation, drinking etc.
Borehole pumps are sized to fit in specific boreholes. The width is measured in inches, typically; 4”, 5”, 6”, 8”, 10” and 12”. The width of the borehole, the depth of the borehole, the fluid, flow rate, pressure/head and power supply details are enough for a pump to be selected correctly.
Sand handling capability changes depending on model. Please consult the data sheet of the specific model you require or contact a member of our sales team for assistance.
Firstly, always check the compatibility of the materials available against the fluid being pumped. The main materials to check are the pump casing, impeller, o-ring, cable and mechanical seal. It may be that more than one material is suitable for your fluid and selection could be based on the application type. For instance; cast iron, bronze and stainless steel are all suitable for fresh water. If it is a simple transfer application, then the most cost-effective material cast iron will be best. However, if it is a sanitary application, then stainless steel or bronze are better choices.
No, definitely not! Submersible borehole pumps will incur damage even after short periods of dry running. The mechanical seal requires lubrication and cooling while the pump is operating. Without the presence of fluid, the mechanical seal will overheat and crack, and this may cause the pump to leak and fluid to enter the motor. There is also the possibility that the motor will burn out as this requires cooling by the fluid during operation. Our advice is to ensure that the pump and motor are always submerged during operation. There are two main ways to ensure the pump only operates in the event of submersion. Firstly, only the operator turns the pump on and off manually when they have a clear view of the borehole. Secondly, fit the pump with a float switch that will automatically turn the pump off once the fluid has dropped to a specific level in the borehole. If you think that dry running is inevitable, then please speak to us and we will try to select a more suitable pump for your application.
