Deep-well & borehole pumps
Oil-filled, canned water-cooled and solar deep-well pumps selected from well geometry, dynamic water level and the duty point.

FOSAI PUMP DIVISION
Industrial pump systems,
selected by the duty point.
FOSAI-developed pump systems for deep wells, sewage, clean-water transfer, irrigation and pressure projects. Start with the application; our engineering structure connects the duty point, product family, curve confirmation and project documentation.
PRODUCT ARCHITECTURE
Three clear duties. Eleven focused product families.
Start with the water source and installation: borehole, wastewater or clean water. Then choose the hydraulic family. This keeps incompatible pumps out of the same comparison and takes customers to the correct series faster.
