Introduction
SPX hose pumps are engineered to enhance process performance through a unique pumping action that ensures 100% compression, providing precise metering and pressure performance without slippage. The design, free from seals, seats, or valves, is ideal for handling abrasive slurries and aggressive products.

Engineered Simplicity
Watson-Marlow Bredel, a leading manufacturer of hose pumps, offers a wide range of pumps suitable for industries such as chemical, water treatment, mining, and food processing. These pumps effectively handle corrosive, abrasive, shear-sensitive, and high-viscosity fluids.

Features and Advantages
SPX pumps are self-priming, capable of dry-running, reversible, and require minimal maintenance. They do not need ancillary equipment like check valves or sealing systems, simplifying operation. The pumps can handle high viscosity products and run dry without damage.

Design and Construction
The SPX pumps feature a direct-coupled design with heavy-duty rotor bearings integrated within the pump rotor, eliminating overhung loads and enhancing reliability. The hoses are made from high-quality compounded rubbers reinforced with nylon layers for perfect compression and consistent performance.

Hose Materials
Available hose materials include Natural Rubber, Nitrile-Buna N, EPDM, and Hypalon, each offering specific chemical resistance and temperature range capabilities.

Applications and Case Studies
SPX pumps are versatile, used in applications such as sludge pumping at sewage treatment works, effluent handling in chemical supply companies, quarry waste management, and food processing.
