Calpeda NMS4 80/400A/B

The Calpeda NMS4 80/400A/B pump is a monoblock centrifugal pump with a cantilever-monoblock format. It is equipped with a horizontal suction pipe and shaft, as well as a vertical discharge pipe. 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 a universal equipment. The power of the Calpeda NMS4 80/400A/B pump is 30 kW, and the voltage is 380 V. The pump provides a pressure of 32.5 to 61.5 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 design completely protects against liquid ingress into the pump's working mechanism, which allows to minimize failures in operation. Under the operating conditions specified in the instructions, the pump operates in continuous mode 24/7. The popularity of the pump in the field of professional water supply and households was ensured by its affordable price and optimal set of characteristics.
