Goulds CWX Pumps for Abrasive Slurries

Summary

Product identification

The Goulds CW/CWX are horizontal pumps designed for abrasive slurries. They are described as Single-Stage, Enclosed-Impeller, Back Pull-Out Process Pumps. The Model CWX features a Shearpeller, providing superior air- and solids-handling capabilities compared to conventional designs.

Operating limits

The document includes hydraulic coverage charts illustrating Total Head versus Capacity for various CW and CWX pump sizes (e.g., 4x3x11½, 16x14x21) at variable RPM. These charts provide performance envelopes for different configurations.

See the official PDF for exact tabulated values and detailed performance curves.

Feed water

These pumps are designed to efficiently pump liquids with abrasive solids in suspension and various types of slurries. The Model CWX with its Shearpeller is specifically engineered to handle large, stringy or fibrous solids, entrained air in water, and viscous materials.

Typical services include:

• Coal Preparation
• Kaolin
• Sugar Mills
• Steel Mills
• Cement Plants
• Aggregates
• Power Generation
• Coal Slurry
• Clay Slip
• Raw Juice
• Scale Pit
• Cyclone Feed
• Sand and Gravel
• Ash Handling Systems

Mechanical / hydraulic

• Standardized Design: Features only three power ends for maximum interchangeability of parts and reduced spare parts inventory.
• Back Pull-Out Design: Facilitates single craft maintenance.
• Shearpeller Option (Model CWX): A patented design that enables pumping of stringy solids and entrained air. Its radial vanes narrow at the eye to allow large or stringy solids to enter, and widen toward the OD for positive pumping action and higher heads.
• Rugged Casing: Made of abrasion-resistant HC600 chrome iron with extra-thick metal sections for maximum operating life.
• Enclosed Impeller: Designed for long life and trouble-free service.
• Renewable Front and Rear Wear Plates: Protect the casing and allow for easy removal and replacement.
• Long-Wearing Shaft Sleeve: An XH-800 hook-type shaft sleeve protects the carbon steel shaft for the full length of the stuff box and extends through the packing gland.
• Heavy-Duty Shaft: Constructed from SAE 1045 steel, designed with minimum overhang to reduce deflection.
• Bearing Protection: Utilizes Taconite with a grease barrier for maximum protection.
• Dynamic Seal Option: Available to eliminate packing and associated maintenance.
• Rotation: Clockwise rotation only, when viewed from the drive end.
• Dimensions: All dimensions are provided in inches and millimeters.
