Horizontal Pumps

Invented in 1938 by Charles Warman who worked in the largest gold mine in Kalgoorlie, Australia, our horizontal centrifugal pumps have been used successfully within a diverse range of mining, chemical and industrial applications. We manufacture and supply a wide range of pumps to handle various applications including dense mineral slurries, froth and other aggressive wear applications. These heavy-duty pumps offer high performance pumping, extended wear life, reduced maintenance and outstanding availability. Whether you need a horizontal slurry pump for a mill-circuit, process, high-pressure, froth, tailings, gravel, dredge or FGD application, we can provide the perfect Warman® pump solution to suit.

Warman® Heavy-duty Slurry Pumps (AH® and AHPP)

For 60 years, Warman® AH® series pumps have been considered the world’s standard for heavy-duty slurry pumping applications (Service Class 1-4). Warman® AH® slurry pumps are specifically designed for the continuous pumping of highly abrasive, dense slurries in processes from hydrocyclone feed to regrind, flotation and tailings in minerals processing plants. These high-pressure centrifugal pumps are available with a variety of impellers and shaft seals to provide the perfect fit for a wide range of applications. The WRT® impeller and throatbush upgrade further enhances the pump's performance by improving its efficiency and reducing power consumption.

Warman® WBH® Heavy-duty Process Pumps

The next generation of our Warman® AH® pumps, Warman® WBH® heavy-duty slurry pumps optimise all aspects of wear and performance while delivering a lower total cost of ownership (TCO). These centrifugal process pumps are typically used in heavy-duty applications such as mill discharge, slurry transfer and process pumping and are suitable for both greenfield and brownfield installations (Service Class 1-4). With your general slurry process pumping requirements front of mind, the Warman® WBH® slurry pump range offers numerous design enhancements based on the latest slurry pumping technology to help ensure productivity demands are met.

Warman® Horizontal Froth Pumps (AHF, LF and MF)

Based on the Warman® AH® series of heavy-duty slurry pumps, the Warman® AHF range of horizontal pumps is specifically designed for pumping froth with fine particles. These pumps are able to handle heavy froth and viscous concentrated non-Newtonian slurries with ease. They have a unique impeller with oversized inducer blades on each vane and a large eye, making the entrained air bubbles dissipate or reduce in size so that they do not inhibit the flow of the slurry. For mineral froths with high froth volume factor, we offer a patented Continuous Air Removal System (CARS) technology upgrade, which has repeatedly demonstrated success in improving froth pumping performance stability in many installations around the world.
