Calpeda NMS 80/250A/A

The Calpeda NMS 80/250A/A centrifugal pump is a cantilever-monoblock type, made with a horizontal suction branch and shaft, and a vertical discharge branch. This design format ensures ease of use and maintenance. pump. Suitable for pumping clean liquids and liquids with contamination. The pump is applicable in almost all areas of economic activity. The pump motor has a modern operating mechanism, ensuring durability and reliability, as well as a reduced noise level. The materials used to manufacture the pump - cast iron, bronze, high-quality stainless steel, brass - increase the service life of the pumping equipment and prevent corrosion and oxidation. Special designs of these pumps allow the ability to work with other environments, including those with high or low acidity. Also, special end seals allow working with numerous water-glycol mixtures. In addition, an explosion-proof design is possible. The monoblock design completely protects against liquid ingress into the pump's working mechanism, which minimizes malfunctions. If the operating instructions are followed, the pump can operate 24/7. The increased demand for the model in the areas of professional and domestic use ensures an optimal ratio of technical characteristics and cost. The capacity of the Calpeda NMS 80/250A/A pump is 55 kW, and the voltage is 380 V. The pump provides a pressure of 76.5 to 95 m, and a capacity of 75 to 192 m³/h.

Variable Speed Pumps (EI)

The NM EI pumps are available with a power of 0.55 kW to 22 kW and are equipped with I-MAT inverters. They enable the implementation of an extremely compact and efficient variable speed system, which is ideal for use in water supply and for the distribution of hot and cold water. The pump is equipped with sensors programmed directly at the factory and programmable by the user for the desired operating mode.
