CWX marine vortex self priming centrifugal pump

Compact, self-priming centrifugal vortex pump designed for marine and industrial water-handling applications. The CWX vortex pump combines a cast-iron pump body, bronze impeller and stainless-steel shaft to deliver reliable service for fresh water, seawater, wash water, sanitary systems and potable water installations.

Key features

• Vortex (non-clogging) impeller profile reduces the risk of blockage and handles entrained air or gas-liquid mixtures better than conventional impellers.
• Self-priming capability with a rated suction lift up to 4 m, enabling installation above the waterline and easier system layouts.
• Compact, lightweight construction for easier installation in constrained marine or equipment spaces.
• Simple mechanical design for straightforward installation and maintenance.
• Available coupling options: closed (rigid) coupling or shaft coupling to suit different motor/drivetrain arrangements.

Materials and construction

• Pump body: cast iron
• Impeller: bronze
• Shaft: stainless steel

Typical performance range

• Flow rate: 3 – 10 m3/h
• Head: 35 – 40 m
• Speed: 2,900 rpm
• Motor power: 2.2 – 4.0 kW
• Typical inlet example: 1.5 (1.5 inch)

Applications

• Marine fresh and seawater systems
• Deck and general washdown systems
• Sanitary and potable water supply (where materials and approvals are appropriate)
• Systems conveying liquids with some entrained air or volatile components

Model coding example

• 1.5CWX-2: “1.5” = pump inlet size (1.5 in); “CWX” = centrifugal vortex pump series; trailing number indicates the unit/series specification (as supplied by the manufacturer).

When specifying, confirm exact inlet/outlet sizes, coupling arrangement, shaft rotation, motor selection and any required corrosion/sea-water options or certifications for your application.
