Calpeda A 80-170A/A

Calpeda A 80-170A/A is a centrifugal self-priming pump with an open impeller. It has a branch pipe that is built into the suction shut-off mechanism - this is one of the main features of the operating principle of the equipment. The pump is free from the effect of reverse suction. If the system is restarted, self-priming action occurs. The equipment can work with contaminated liquids, which allows it to be used in many areas. The Calpeda A 80-170A/A pump is used for irrigation of agricultural lands, where it is necessary to take water from reservoirs, when operating shallow wells, when installing storm drain stations, such pumps also implement drainage of flooded rooms and territories, and pump out some industrial liquids. When using special designs in a bronze body with special end seals, it is used in fish farms, in industries requiring the use of saline solutions and when using aqueous solutions of propylene glycol and ethylene glycol. If the operating conditions are met, the equipment can operate in continuous operation mode 24/7. The capacity of the Calpeda A 80-170A/A pump is 7.5 kW, and the voltage is 380 V. The pump provides a pressure of 20.4 to 33.6 m, and a capacity of 15 to 66 m³/h. The pump body and parts are made of modern high-quality materials that provide reliable protection against corrosion, resist oxidation and potential mechanical damage. The materials used are cast iron, bronze, chromium-nickel, chromium and chromium-molybdenum steel.
