Calpeda 6SD 20/6

The Calpeda 6SD 20/6 pump is a submersible borehole pump and has high performance due to the use of modern technologies. It fully complies with international quality standards. One of the main distinguishing features is high reliability. The Calpeda 6SD 20/6 pump is equipped with an external casing made of stainless steel (AISI 304), a shaft made of chromium-nickel-molybdenum steel (AISI 316), which allows using the equipment in deep wells. The check valve is built into the socket of the feed part. In addition, the pump has a compact design and is easy to operate. It is suitable for use in various industries and areas: industrial and domestic facilities, irrigation in agriculture, housing and communal services and construction, can be used as equipment for fire-fighting systems. In addition, it can be used in open water in a horizontal and vertical position with an additional cooling jacket. Versions with motors for wells with an increased temperature regime, as well as with other voltages and a frequency of 60 Hz are possible. The pump can pump clean and slightly contaminated liquids with some solid particles. The engine is designed to work with an inverter. The power of the Calpeda 6SD 20/6 pump is 13 (15) kW, and the voltage is 380 V. The pump provides a pressure of 34 to 93 m, and a capacity of 12 to 57 m³/h.
