Calpeda NR 40/200B

The Calpeda NR 40/200B centrifugal pump has proven itself very well and is in great demand both in the industrial segment and in domestic use. This model is successfully used to ensure uninterrupted operation of equipment used in heat supply, including inter-quarter boiler houses, air conditioning, cooling and circulation systems. Important components of the pump are made of high-strength materials: cast iron, brass, chrome and chrome-nickel steel, which allows interaction with high-temperature and low-temperature liquids. Special versions of this pump allow pumping sea water, industrial salt solutions of low concentration, aqueous solutions of propylene glycol and ethylene glycol, as well as caustic soda solutions, distilled and demineralized water, environments with high and low temperatures, as well as hot oil up to 200 degrees. It is also possible to design the pump for other voltages and other frequencies (60 Hz). The pump is designed to work with an inverter. The compact size of this model allows it to be installed in a limited area. The well-planned geometry of the impeller allows achieving high efficiency rates and good suction capacity. And the economical asynchronous electric motor ensures uninterrupted operation of the equipment in the mode of excessive loads. The power of the Calpeda NR 40/200B pump is 3 kW, and the voltage is 380 V. The pump provides a pressure of 22 to 40.2 m, and a capacity of 6.6 to 21 m³/h.
