Multistage semiaxial submersible electric pumps for wells measuring 8” 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 160 m3/h with head up to 380 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/-2 m depending on the working point of the electric pump.
Installation: horizontal or vertical.
CONSTRUCTION FEATURES OF THE PUMP
Pump body in cast iron with paint coating, impellers in cast iron. Dynamically balanced impellers coupled on the shaft with pull tab. Shaft guided with coaxial bush bearings and fully protected with bushes. Pump with check valve of low pressure loss. Flanged and threaded discharge port. Coupling with motors of 6”, 8” or 10” depending on the required hydraulic power:
6GF: encapsulated 6” submersible motor.
TR6: rewindable 6” submersible motor.
TR8: rewindable 8” submersible motor.
TR10: rewindable 10” submersible motor.
For operation with inverter see the specifications of the coupled motor.
