N Condensate Water Pump

Designed for industrial condensate handling, this horizontal cantilever condensate pump moves condensate and other clear liquids (with physical and chemical properties similar to water) at temperatures up to 120°C. The N-series is engineered for compact installation, reliable continuous operation and high hydraulic efficiency, with good cavitation resistance and a high degree of standardization for interchangeability and easier maintenance.

Key technical highlights

• Performance range: flow 10–100 m3/h; head 12–141 m
• Maximum liquid temperature: up to 120°C (NB / NBA types recommended for lower-temperature applications described below)
• Construction: horizontal cantilever centrifugal design with single-suction configuration; N-type available in multi-stage arrangements
• Materials: flow-path components available in cast steel or stainless steel; alternative materials available on request to meet specific service conditions
• Design options: available with or without inducer; suspension-frame (B) configuration available for certain models

Typical applications

• Condensate extraction from condensers
• Condensate return for steam turbine generator sets (models NB / NBA typically used for condensate from 750–3000 kW units)
• General industrial condensate transfer and similar duties where the liquid is close to the properties of clear water

Model coding (how to read common model numbers)

• Example: 3n6x2

  • "3" = 3-inch inlet diameter
  • "N" = horizontal cantilever condensate pump
  • "6" = head factor (head × 10 → 6 corresponds to ~60 m head)
  • "2" = number of stages

• Example: NB100-45

  • "100" = 100 mm inlet diameter
  • "N" = condensate pump series
  • "B" = suspension-frame variant
  • "45" = nominal head 45 m

Advantages for buyers

• Compact footprint and simplified installation for retrofit and new-build projects
• Stable, reliable running suitable for continuous condensate duties
• High standardization reduces spare-part variety and simplifies maintenance planning
• Material and configuration options allow tailoring to site-specific chemistry and temperature requirements

Ordering and specification notes

Provide the required flow (m3/h), head (m), liquid temperature, inlet/outlet connection sizes, preferred materials, and whether an inducer or suspension frame is required. This ensures selection of the correct N / NB / NBA variant and stage configuration for the application.
