The WATERAX BB-4 ® Series is a full line of high pressure centrifugal pumps that has been used by forest agencies for over 40 years. It has become the weapon of choice in wildland operations. The BB-4 ® comes in portable & vehicle mounted configurations and is powered by Briggs & Stratton Vanguard 18HP and 23HP or Honda 21HP 4-stroke engines to achieve pressures up to 440 PSI (30.3 BAR) and flow rates reaching 106 US GPM. All BB-4 ® models feature a unique greaseless sealed bearing and a blister-resistant mechanical rotary seal. These latest improvements significantly reduce field maintenance and prolong pump end longevity.
