DESCRIPTION

180 SX Series 8” Submersible Borehole Pump

Flow Rate	Up to 192m³/hr (3200 L/min)
Head (Pressure)	Up to 472m
Inlet/Outlet Sizes	5” GAS (F)
Operating Temperature	Up to 35°C
Drive Options	Electric Motor

The 180 SX range of 8” submersible borehole pumps are made completely of stainless steel AISI 304 and offer a wide range of flow rates up to 192m³/hr and pressures up to 472m (47.2 Bar).

This type of pump is commonly used when there is not a limitation on well diameter and relatively

high flows and heads are required.

This is a robust series of multistage submersible pump and it can achieve medium capacities and high heads due to it's unique impeller and diffuser design. It is highly efficient, long lasting and easy to maintain due to highly advanced micro casting technology.

This 8” borehole pump range is excellent at supplying ground water or boosting pressure to industrial properties, extracting water from wells, mine dewatering, fire fighting and irrigation. Pumped fluids must be clean, thin, non-aggressive and compatible with the installed materials.

PLEASE NOTE THAT ONLY THE BOREHOLE PUMP IS SUPPLIED AS STANDARD, THE MOTOR MUST BE ORDERED SEPERATELY. PLEASE FOLLOW THE LINK TO OUR MOTOR RANGE TO SELECT A SUITABLE MOTOR.

FAQS

What is a borehole?

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.

How do I know what size pump is correct for my application?

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.

What percentage sand content can this pump handle?

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.

How do I know what pump materials are correct for my application?

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.

Can this pump run dry?

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.
