Feed water pumps

Vertical, multistage centrifugal feed water pumps engineered for water and light industrial liquid transfer. These compact, space-saving pumps use a multistage impeller assembly to achieve high discharge pressures with stable flow, making them suitable for pressurization, process supply and treatment applications.

Key features

• Multistage centrifugal design for high pressure at moderate flow rates
• Vertical, inline construction saves floor space and simplifies piping
• Stainless-steel wetted parts (CDLF variant) for improved resistance to slightly corrosive liquids; CDL variant for non‑corrosive liquids with a cast-iron pedestal
• Suitable for a wide range of fluids from potable water to many industrial liquids at various temperatures
• Robust mechanical seal arrangements and compact hydraulic design for reliable operation and low maintenance

Variants and construction

• CDL: for non-corrosive liquids — cast-iron inlet/outlet pedestal
• CDLF: for slightly corrosive liquids — full stainless-steel inlet/outlet pedestal

Typical applications (B2B)

• Municipal and industrial water supply: filtration, distribution, zone delivery, main-pipe pressurization
• Building services: high-rise building pressurization and booster systems
• Industrial process pressurization: cleaning, high-pressure flushing, process water supply
• HVAC and energy: cooling circuits, boiler feed and condensate transfer
• Water treatment systems: ultrafiltration, reverse osmosis, distillation and separators
• Support for manufacturing equipment and ancillary systems requiring pressurized liquid delivery

Benefits for buyers

• Compact vertical layout reduces plant footprint and simplifies installation
• Multistage configuration delivers higher discharge pressures without oversized motors or single-stage extremes
• Stainless-steel option extends service life with mildly corrosive liquids, lowering lifecycle costs
• Modular staging and standard mechanical interfaces ease spare-part management and maintenance

Example model reference

• Model: CDLF2-130 (example of CDLF series multistage vertical pump)

Spec selection guidance

For accurate selection provide required flow (m3/h or GPM), required discharge pressure (m or bar), liquid temperature, and fluid corrosivity. This enables sizing the number of stages, motor rating and material selection (CDL vs CDLF) to meet system duty and service conditions.
