Design: Monoblock centrifugal pumps with direct connection between the engine and the pump and a common shaft. Pump body with axial suction port and upper radial delivery socket; main dimensions and performance according to EN 733 with other optional dimensions.
Application: Pumping of clean liquids that are not aggressive to materials and do not contain abrasive impurities from which the pump is made (solids content max. 0.2%). Water supply. Use in heating, air conditioning, cooling and circulation installations. If necessary, work with a reduced noise level. Irrigation. Use in household and industrial areas.
Operational restrictions: - Manometric suction lift no more than 7 m. - Maximum allowable end pressure in the pump casing: 10 bar. - Continuous operation. - Fluid temperature from -10°C to +90°C. - Ambient temperature not more than 40°C.
