Mechanically Sealed Centrifugal Pumps

Available in various sizes and configurations, mechanically sealed centrifugal pumps are a versatile choice for chemical processing and fluid-handling applications. Used independently or integrated with tanks, filters, or valves, pump selection depends on fluid type and viscosity. Seals protect against contaminants to maintain efficiency and extend service life.

Key features:

• Capacity: standard pumps up to 500 m3/h
• Heads: up to 16 bar
• Manufactured in line with ISO 2858/DIN 24256 standards
• High hydraulic efficiencies achieved with low NPSH (Net Positive Suction Head)
• Options for shaft sealing include packed stuffing box and single or double mechanical seals
• Pump casing and seal housing can be equipped with heating or cooling chambers as needed
• Units up to 30kW size can be close-coupled to motors with B5 flange using a support lantern
• Large variety of impeller options – open or closed
• Suitable for contaminated, corrosive or abrasive fluids
• Options for high or low viscosity fluids
• Suitable for gas-entrained liquids
• Low flow/high head pumps available

Materials of construction:

• Metallic: cast iron, ductile iron, Hastelloy C, stainless steel, super duplex
• Non-metallic: lined with PFA (PerFluoroAlkoxy), PVDF (Polyvinylidene Fluoride) or Polypropylene
