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 aluminum 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.

Use Cases

WATERAX has a 125-year track record conceiving and manufacturing industry-leading water pumps and innovative water-moving solutions designed to withstand demanding use and the rugged environments in which they are operated.

 

FireProtection

Wildland fire prevention and protection is an everyday action to prevent potential destruction and reduce the impact of uncontrolled fires.

 

FireApparatus

Fire agencies need versatile, rugged and portable equipment for wildland and wildland-urban interface (WUI) applications to transport firefighters, hoses, pumps, fittings, water and all other related equipment. Due to the remote locations of wildland fires, getting to sites generally requires four-wheel drive and off-road capabilities.

WATERAX provides centrifugal fire pump models for type 4, 5, 6 and 7 wildland engines. To complement our high-pressure fire pumps, WATERAX offers a wide selection of components, such as control panels and manifolds, tailored to the needs of fire apparatus manufacturers who create brush trucks, skid unit slip-ons, trailers and sprinkler systems.

 

Commercial

WATERAX portable pumps are widely used for wildland fire protection but they are also used in farm fields, oil fields, construction sites, marinas, golf courses and even to make ice bridges and snow.

To be efficient, a power pump must be lightweight, capable of generating high pressure and, most of all, reliable. WATERAX pumps are single- or multi-stage centrifugal pumps. This system allows for pumping from natural water sources (lakes, streams, rivers, pools, etc.) which often contain minor debris. Centrifugal systems also allow for tandem pumping and are able to pump water over large distances and points of elevation.
