6" Well pumps

Summary

Product Identification

The S6 series consists of multistage, centrifugal, submersible motor-driven pumps designed for 6” wells or larger. They are capable of generating a vast range of heads and flow rates.

Applications:

• Lifting, distributing, and pressurising in civil and industrial water installations.
• Supplying autoclaves and cisterns.
• Fire fighting and washing systems.
• Irrigation systems.

Operating Limits

• Operating range: Up to 66 m³/h with heads up to 468 m.
• Max. ambient temperature: 30˚C.
• Starts/hour: Max 20.
• Minimum recommended level on suction: 1 metre.

Feed Water

• Pumped liquid: Clean, free from solid or abrasive substances, chemically neutral, and close to the characteristics of water.
• Max. quantity of sand: 40 g/m³.

Electrical

• Motor type: Asynchronous 2-pole submersible motor.
• Protection level: IP 68.
• User-provided protection: Protection devices must be provided by the user according to EN 60947-4-1 (Cut-in delay <10 sec. at 5 x In).
• Voltage: 3 x 400 V ~ for both Direct Starting and Star/Delta Starting models.

Electrical Data (per model):

• P2 Nominal (kW, HP)
• In (A)

See the official PDF for exact tabulated electrical values for each model.

Mechanical / Hydraulic

Pump Constructional Characteristics:

• Base support and upper head: Stainless steel AISI 304.
• Bottom support: Dimensioned to NEMA 6” standard.
• Check valve: Incorporated in the supply support.
• Bush bearings: Bronze rubber.
• Spline shaft: AISI 420, entirely protected.
• Consumable rings, spacer tubes for diffuser body, cable protection, suction grille: AISI 304 stainless steel.
• Impellers and diffusers: Noryl.

Motor Constructional Characteristics:

• Material: Totally built from AISI 304 stainless steel.
• Rotor: Squirrel-cage rotor mounted on a self-centring thrust block bearing suitable for withstanding axial loads.
• Stator: Inserted in a stainless steel airtight casing.

Hydraulic Data (per model):

• DNM GAS (Discharge Nominal): 3”
• Weight (KG)
• H (mm)

See the official PDF for exact tabulated mechanical and hydraulic values for each model.
