Leo 4SR16-13 / 3.7KW Submersible Borehole Pump Only » Buy online now for only R 5,573.36 incl. VAT

The LEO 4SR16-13 is a robust submersible borehole pump engineered for reliable water supply, irrigation, and air conditioning circulation systems. This single-impeller centrifugal pump delivers up to 220 m3/h with heads reaching 85 meters, making it ideal for deep well installations and demanding transfer applications involving clean, chemically non-aggressive liquids across a wide temperature range.

Built with a corrosion-resistant AISI304 stainless steel impeller and featuring a mechanical seal compliant with DIN 24960, the 4SR16-13 combines durability with low-maintenance operation through internal recirculating lubrication. Its rear-entry design allows for easy extraction of the impeller, control valve, and motor without disconnecting the pump body from the pipework, while the closed motor construction with IP54 protection and Class F insulation ensures dependable performance in challenging borehole and submersed environments.
