Calpeda NMM 3/B

Description

The Calpeda NMM 3/B centrifugal pump has a monoblock type and solves a wide range of tasks in the processing industry, agriculture, housing and communal services and consumer services. It is suitable for carrying out agricultural irrigation, ensuring the operation of heat supply, cooling and water circulation, and the functioning of fire-fighting equipment. The basis of the pump design is a monoblock, in which a direct connection and a common shaft are installed between the motor and the pump. The liquid channels were designed to reduce noise levels. The increase in efficiency is achieved due to the well-thought-out dynamics of fluid flow at the junction of the impeller and the equipment body. The two-pole asynchronous motor of the pump has a modern operating mechanism, ensuring durability and reliability. The special body designs of this pump make it possible to work with seawater, salt solutions, slightly acidic and slightly alkaline media. The pumps are equipped with a convenient threaded connection, which is optimal for most networks in their field of application. The pump can also be manufactured with a different voltage and frequency and with additional protection against liquid entering the housing. The pump can be operated with an inverter. The materials of which the pump consists are cast iron, bronze and stainless steel of high quality, which allows protection against corrosion and oxidation. The power of the Calpeda NMM 3/B pump is 1.5 kW, and the voltage is 220V V. The pump provides a head from 32 to 42 m, and a capacity from 1.2 to 6 m3/h.
