The BB-4® Series is a full line of high-pressure centrifugal pumps that has been used by forest agencies for over 40 years in Type 6 brush trucks. It has become the weapon of choice in wildland operations. The BB-4® comes in portable and vehicle-mounted configurations and all models feature a unique greaseless sealed bearing and a blister-resistant mechanical rotary seal. A unique feature of the BB-4® pump is the quick-release pump end that is interchangeable with the MARK-3® pump, which greatly reduces your spare parts inventory and allows for quick infield swap outs.
