Industrial water supply requirements are met by the Calpeda MXSM 903, which is used for clean water transfer from reservoirs, tanks, or wells. Suitable for civil applications and garden irrigation, it operates with clean liquid at temperatures up to 35°C. The pump is designed for continuous duty and standing installation.
This 1.1 kW single-phase model provides a high maximum flow rate of 183 L/min and reaches a maximum head of 28.2 m. Operating at 240v with a 7 Amp rated current, the motor is cooled by the pumped fluid flowing between the jackets, supporting operation during partial submersion.
Multi-stage hydraulics feature stainless steel impellers for clean water transfer through the stage casings. An integrated suction strainer restricts the entrance of solid particles to those no bigger than 2 mm in diameter, protecting the internal components. The compact 5-inch design fits wells with a 140 mm minimum diameter.
Mechanical construction features a chrome-nickel stainless steel AISI 304 delivery casing and external jacket. Motor protection is provided by a double mechanical shaft seal with an oil chamber. The single-phase motor includes an incorporated capacitor, a built-in thermal protector, and a triple impregnation humidity-proof dry winding.
FEATURES
- Manufactured using chrome-nickel stainless steel AISI 304 for all parts in contact with the fluid.
- Double mechanical shaft seal with oil chamber provides motor protection and lubrication for the shaft seal.
- Oil for food machinery and pharmaceutic use is used within the shaft seal oil chamber for lubrication.
- Motor is cooled by the pumped fluid passing between the jacket and external shell during service.
- Integrated suction strainer restricts the entrance of solid particles with a diameter bigger than 2 mm.
- Single-phase 240v motor includes an incorporated capacitor and a built-in thermal protector for safety.
- Motor features a triple impregnation humidity-proof dry winding designed to EN 60335-2-41 standards.
