Pozzani 2" Borehole / Well / Tank Submersible Pump - Stainless Steel Screw Auger Pump - 0.55kw - 40m Cable

Screw auger pumps are designed for pumping water from boreholes or wells. They usually consist of a long, spiral screw that turns and lifts the water up the borehole to the surface. They are commonly used in areas with low yields or where other types of pumps are not feasible. They are well-suited for pumping water from sandy or fine-grained soils. In such soils, installing a gravel pack can be challenging and may not yield the desired results. In these situations, a screw auger pump is often a more effective solution.

One of the greatest benefits of a screw auger pump is its simple design. The screw is usually made of steel or plastic and is easy to replace if it gets damaged. The pump doesn't require a lot of maintenance and can be easily cleaned or repaired if needed. This makes it a cost-effective option for many people.

The output of a screw auger pump is also typically low, making them ideal for low-yield well situations. These pumps work best with a small, constant flow of water and can produce large quantities of water over an extended period.

Advantages:

• Self-Priming: One of the biggest advantages is that the screw pump is self-priming. Because of the axial design, the pump can easily draw the liquid through the suction inlet without a separate priming mechanism.
• Low maintenance: Screw pumps have fewer moving parts, which means less opportunity for wear and tear. As a result, they require less maintenance and have fewer unplanned downtimes.
• Handles liquids and solids: Screw pumps can handle liquids and some solids, without clogging or damaging the pump. 

Disadvantages:

• Limited flow range: Screw pumps are best suited for low to moderate flow rates. High flow rates can cause some issues with cavitation, which can damage the pump and decrease efficiency.
• Not suitable for viscous liquids: Screw pumps are not suitable for highviscosity liquids, as the water can cause excessive wear and tear on the screws.
• Requires specific setup: Screw pumps require special installation techniques, such as proper alignment, and correct feed and discharge head pressures in order to function properly. Failure to do so can result in reduced pump life and performance.
