Materials of Construction

The pumps feature AISI 316 stainless steel construction with a flanged drive head for IEC standard electric motors.

Key components and their materials include:

• Pump Body, Impeller, Diffuser, Inlet, Ring, Bush, Sleeve, Foot Valve, Strainer, Gasket, Adapter, Spring, Screws, Nuts, Washers: AISI 316 stainless steel
• Shaft (Pump, Lineshaft): DUPLEX AISI 329 stainless steel
• O-Rings: Fluoroelastomer
• Bearings: PTFE
• Wear Ring: POM
• Drive Head Components:
  • Electric motor support, cover, coupling plate, half couplings: Cast iron
  • Stud bolts: AISI 304 stainless steel
  • Seal ring, small block: Rubber
  • Other components (nuts, bearings, screws, grease, key, shaft, pin, protection, ring nut, washer, seeger): Steel
• Discharge Base Components:
  • Base, mechanical seal cover, bush: AISI 316 stainless steel
  • Stud bolt, nut, screw: AISI 304 stainless steel
  • O-Ring: Fluoroelastomer
  • Mechanical seal: WIDIA (adjustable cartridge type)
  • Other components (support, plate, locking device, dowel pin, protection, washer): Steel
• Lineshaft Components:
  • Shaft: DUPLEX AISI 329 stainless steel
  • Bush, bearing support, key, seeger, pipe, coupling, screw, nut, washer: AISI 316 stainless steel
  • Bearing: PTFE
  • O-Ring: Fluoroelastomer

A special coupling design allows for mechanical seal removal without disassembling the motor.

Hydraulic Characteristics

• Pump performances are referred to cold water (20°C) at atmospheric pressure (1 bar) and are guaranteed according to ISO 9906 Grade 3B norms.
• Catalogue data refers to liquids with a density of 1000 kg/m³ and a kinematic viscosity not higher than 1 mm²/s.
• Available for 50Hz and 60Hz operation.
• Performance curves are provided for liquid density 1000 kg/m³, viscosity 1 mm²/s, and temperature 20°C.
• See the official PDF for exact tabulated values and performance curves for specific models (e.g., 6VX24/2, 6VX24/3, etc.) at different RPMs (1750 min⁻¹, 2900 min⁻¹, 3500 min⁻¹).

Electrical Characteristics

• Designed for use with flanged IEC standard electric motors.
• Closed asynchronous electric motors are available in 2 or 4 pole configurations, suitable for 50Hz and 60Hz frequencies.
