Calpeda NMD 32/210A/B

The Calpeda NMD 32/210A/B centrifugal pump is a monoblock type and solves a wide range of problems in the processing industry, agriculture, housing and communal services and household services. It is suitable for agricultural irrigation, ensuring the operation of heat supply, cooling and water circulation, and the functioning of fire-fighting equipment. The pump design is based on 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 the noise level. The efficiency is increased due to the well-thought-out dynamics of the liquid 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. Special designs of the body of this pump allow it to work with sea water, salt solutions, weakly acidic and weakly alkaline environments. The pumps are equipped with a convenient threaded connection, which is optimal for most networks in their area of application. The pump can also be manufactured with a different voltage and frequency and with additional protection against liquid ingress into the body. The pump can operate with an inverter. The materials of which the pump consists are cast iron, bronze and high-quality stainless steel, which protects against corrosion and oxidation. The power of the Calpeda NMD 32/210A/B pump is 9.2 kW, and the voltage is 380 V. The pump provides a pressure of 90 to 114 m, and a capacity of 5.4 to 15 m³/h.
