Multistage semiaxial submersible electric pumps for wells measuring 6” or above, able to generate a broad range of flow rates and heads. They are used extensively for the lifting, distribution and pressurisation of industrial water systems, the supply of autoclaves and tanks, firefighting systems and irrigation systems. Application with clean, non-aggressive water free from solids or abrasive substances.
Operating range: up to 85 m3/h with head up to 390 m.
Pumped liquid: clean, free from solids or abrasive substances, chemically neutral, close to the characteristics of water.
Start-ups/hour: see the coupled motor.
Cooling flow: see the coupled motor.
Maximum permitted amount of sand: 50 g/m3.
Ambient temperature: 30 °C.
Minimum recommended level on suction line: 1 m.
Installation: horizontal or vertical.
Electric pumps complying with the 2009/125/EC Directive
