Calpeda BN 40-125A/A

The single-stage centrifugal pump Calpeda BN 40-125A/A has unrivaled versatility and has many functions, so the model is popular in various water supply industries, in the agricultural sector, in households and housing and communal services. The pump is suitable for clean liquids that do not contain aggressive elements that can negatively affect the materials of the pump. In addition, the pumped liquid must not contain solids, suspended particles and gaseous substances. The pump can be used both at low and high temperatures, so it is suitable for use in heat supply, air conditioning and simple water circulation. The centrifugal pump Calpeda BN 40-125A/A is used for watering garden plots and agricultural fields, ensures the functioning of fire-fighting equipment, residential and commercial buildings. Due to its design features, the asynchronous motor and the pump part can be dismantled separately. Special versions of this pump in a bronze body can be used for pumping sea water and brine. Also, with special end seals, the pump can be used in high-temperature mode for water and oil. The power of the Calpeda BN 40-125A/A pump is 2.2 kW, and the voltage is 380 V. The pump provides a pressure of 11.5 to 22 m, and a capacity of 15 to 42 m³/h. Corrosion resistance is provided by the materials from which the pump is made (cast iron and chrome steel). Under the operating conditions specified in the instructions, the pump functions in continuous mode 24/7.
