Watson Marlow Apex Pump


Leading the world in hose pump innovation, Bredel introduces its new APEX range, the optimized pump of choice for dosing, metering and transfer duties between 0.7 – 317 gallons per hour (2.8-1,200 l/hr)

Robust, reliable, and flexible, APEX sets the new standard for lowering life cycle cost in tough industrial applications.

New APEX™ range: five models to cut pump maintenance

The APEX pump from Bredel has set the standard for lowering acquisition, operating and maintenance costs for low to medium pressure
applications. APEX is designed for dosing, metering and transfer duties from 0.012 GPM (2.8 L/hr) to 27.3 GPM (6,200 L/hr) at pressures up to 116psi (8 bar).

The higher flow per revolution means APEX pumps can be run at lower speeds, increasing hose life and reducing wear. With no costly wear
components such as seals, valves, membranes or rotors to maintain, APEX is ideal for handling abrasive slurries and aggressive chemicals.

The precision machined hose element and optimized hose compression ensures accurate and repeatable performance. A choice of hose
materials ensures compatibility with a wide range of fluids including aggressive chemicals, abrasive slurries and fluids with high solids content.

Compared with other pump types, APEX uptime periods are significantly longer. Maintenance consists of replacing a single hose element, a task that can be performed in minutes.

A robust direct-coupled design fully protects the gearbox; competitively priced against lower-cost, less robust close-coupled hose pumps.
