Submersible pump CALPEDA 6SDN 18/16 (22kw)

The CALPEDA 6SDN 18/16 pump, with 22 kW power, is an industrial deep-well pump featuring increased flow capacity and optimal pressure. The 18-series hydraulics deliver high water volumes with low energy consumption and stable long-term performance.

The pump is engineered for extended operation under harsh conditions; the casing and internal components are made from AISI 304 and AISI 316 stainless steel. The built-in strainer protects the hydraulic stages from abrasive particles up to 150 g/m³. The pump can operate in both vertical and horizontal positions (when using a cooling sleeve).
