FAQ

Q1: What is a Submersible Geothermal Pump for Small Diameter Deep well used for?

A small diameter geothermal pump is designed for extracting hot underground water from geothermal wells with limited casing space. It is commonly used in geothermal heating, industrial water supply, and renewable energy projects.

Q2: Why use a small diameter pump instead of a standard deep well pump?

Small diameter pumps are designed for wells where casing size is restricted. They provide reliable water extraction performance while fitting into narrow boreholes that cannot accommodate standard pumps.

Q3: Can this pump work in high temperature geothermal wells?

Yes. The pump can be customized with heat-resistant motor insulation, sealing systems, and materials according to geothermal temperature requirements.

Q4: How do I select the correct geothermal pump model?

Selection depends on well casing diameter, well depth, required flow rate, lifting height, water temperature, and geothermal water quality. AOTE can provide a complete pump system recommendation.
