Recommended Pump Types for Concrete Cisterns?

Choosing the Right Pump for Your Concrete Cistern

When selecting a pump for a concrete cistern, consider factors such as water level, flow rate, and pressure requirements. Submersible pumps are ideal for shallow cisterns with a static water level of up to 10 meters (33 feet), as they can be fully submerged in the water and are relatively low-maintenance. A suitable example would be the Zoeller Sump Pump, which operates at a flow rate of 10 gallons per minute (GPM) and a pressure of 10 feet.

Pump Installation and Maintenance Considerations

For deeper cisterns or those requiring higher flow rates, centrifugal pumps are a more suitable option. These pumps can handle up to 100 GPM and pressures of up to 100 feet, making them suitable for larger cisterns and more demanding applications. When installing a pump, ensure it is properly secured and protected from debris and electrical hazards. Regular maintenance such as cleaning the pump and checking electrical connections is also crucial to ensure optimal performance and extend the pump’s lifespan.

Diaphragm Pumps for High-Pressure Applications

Diaphragm pumps are another option for concrete cisterns, particularly when high pressure is required for irrigation or other applications. These pumps use a flexible diaphragm to create suction and displacement, making them suitable for handling dirty or contaminated water. A suitable example of a diaphragm pump is the Wilden AODD Pump, which operates at pressures of up to 100 psi and flow rates of up to 30 GPM. When selecting a diaphragm pump, consider factors such as water temperature, viscosity, and potential for clogging.
