Submersible pump ESPA ES4 2 20 O4I M 1.1 kW
ESPA ES4 2 20 O4I M (1.1 kW) is a high-power pump designed for operation in deep wells and systems requiring increased pressure. The hydraulic design with floating impellers allows the pump to handle water containing small mechanical particles without the risk of jamming.
The model is equipped with a built-in check valve that prevents backflow and eliminates water hammer, extending the service life of the pipeline and the entire system. The use of the NEMA standard ensures perfect coupling with the electric motor and enhanced reliability of the assembly.
The pump operates equally effectively in both vertical and inclined positions, allowing installation in non-standard wells or narrow shafts. This makes the model suitable for domestic, agricultural and industrial water-supply applications.
Advantages of ES4 2 20 O4I M:
▪️ 1.1 kW power — increased head and stable flow rate;
▪️ high wear resistance and long lifespan;
▪️ no need for additional water-hammer protection;
▪️ flexible installation: vertical or inclined;
▪️ ideal for water-supply systems, irrigation and pumping stations.
