The WATERAX Way
WATERAX is proud to continue its almost century-long tradition of designing, manufacturing and supporting high-performance and durable portable pumps. The key to its success lies in its ability to craft high quality components which form the cornerstone of superior and dependable pump performance.
Detachable multi-stage pump ends
WATERAX performance and dependability come from our superior multi-stage pump end design that provides unrivaled pressure and volume.
Unique blister resistant mechanical rotary seal to prolong pump end longevity. Maintenance free sealed bearing to avoid the need for greasing the pump end in the field. Anodized aluminium impellers and pump body which eliminate galvanic corrosion common with bronze impellers.
Low maintenance drive assembly
Originally designed for the BB-4, the WATERAX low maintenance drive assembly has been time-tested under the most difficult conditions and proven to be dependable and reliable for more than 40 years.
Innovative quick release clamp
Our innovative pump end quick release clamp provides ease of maintenance without having to disassemble the complete unit, thus significantly reducing equipment downtime, which can prove crucial in emergency situations.
Convenient 2-in-1 system
The WATERAX 2-in-1 system enables the easy interchanging of pump ends in the field. The platform is also compatible with either a high-pressure or a mid-range pump end, providing users with maximal performance flexibility at the lowest possible cost.
The WATERAX Platform
WATERAX offers of a complete line of high performance pump ends suited to meet the most difficult water handling requirements. The WATERAX platform is composed of a low maintenance drive assembly, a Mid-Range pump end and three high-pressure pump ends. The platform’s unique feature is its quick release clamp system which allows for the hook up of any WATERAX pump end to its drive assembly as well as almost instantaneous pump end detachment and interchange. This reduces equipment downtime, increase its flexibility and significantly cuts costs. These components are ideal for original equipment manufacturers looking to adapt high quality pump ends to their respective fire apparatus.
High-pressure pump ends
The WATERAX high-pressure centrifugal pump ends are offered in 4-stage, 3-stage, and 2-stage configurations. They deliver pressure up to 440PSI (30.3 BAR) and flows reaching 106 GPM (401 L/min) and are ideal pump ends for moving water over long distance and high elevation.
In addition, all these pump ends have interchangeable spare parts. This helps keep inventory levels and costs low while maximizing the utility and versatility of each stored part. The quality, reliability and durability of these pump ends are what makes them the most trusted in the fire industry.
Mid-range pump end
The WATERAX B2X is a Mid-Range 2-stage centrifugal pump end that delivers pressure up to 200 PSI (13.8 BAR) and flows reaching 300 US GPM (1136 L/min). A strong show of pressure and volume it is the ideal pump end for dual attack lines dedicated to wildland & urban interface operations.
It is also perfect for high volume remote watering, booster line applications, brush trucks, slip-on units and for uphill tandem operations. The suction and discharge use a combination of Victaulic and national pipe threads to facilitate its plumbing.
WATERAX offers an outstanding drive assembly that boosts the performance of pump ends. The drive assembly increases the speed of pump revolutions resulting in increased pressure and volume. The drive assembly is used with the WATERAX quick release clamp to enable the coupling of the drive assembly to the desired pump end.
