Calpeda NM4 80/20A/B

The Calpeda NM4 80/20A/B pump is a monoblock centrifugal pump with a cantilever-monoblock format. This pump design ensures long-term operation and ease of maintenance. The pump can be used with clean liquids and liquids with a share of contamination, which allows classifying the pump as universal equipment. The power of the Calpeda NM4 80/20A/B pump is 4 kW, and the voltage is 380 V. The pump provides a pressure of 6.9 to 14.2 m, and a capacity of 30 to 132 m³/h. Cast iron, bronze, stainless steel and brass are the materials from which the pumps are made. They provide high reliability and protection against corrosion and oxidation. Pumps of this series have a significant mass, which allows to avoid vibration overloads as much as possible and has a positive effect on the engine life. The pumps are well suited for critical areas that support long-term continuous operation. Special versions with other voltage and frequency are possible. The monoblock structure completely protects against liquid ingress into the pump's working mechanism, which helps minimize malfunctions. Under the operating conditions specified in the instructions, the pump operates continuously 24/7. The pump's popularity in the professional water supply and household sectors was ensured by its affordable price and optimal set of characteristics.
