The Calpeda MXSM 503 is a high-performance stainless steel submersible multistage pump designed for clean water supply, pressure boosting and irrigation applications. Engineered for operation in wells, tanks and reservoirs, the pump features a vertical multistage hydraulic design that delivers strong pressure with efficient flow in a compact submerged unit.
Constructed from corrosion-resistant stainless steel, the MXSM 503 offers excellent durability and long service life in domestic, agricultural and light commercial installations. The multistage impeller system enables the pump to produce high heads, making it ideal for lifting water from depth and supplying elevated distribution systems.
Powered by a robust electric motor designed for continuous submerged operation, the pump delivers flow rates up to approximately 120 litres per minute with a maximum head around 42 metres. The motor is cooled by the surrounding liquid, ensuring safe operation even during extended use.
Suitable for clean water free from solids, the MXSM 503 is commonly used for boreholes, rainwater harvesting systems, tank transfer and household pressure supply. Its slim profile allows installation in confined spaces while maintaining reliable performance and quiet operation.
