Description

The Wildfire model BB-4® portable fire pump is an ideal unit for high volume remote watering, brush truck and slip-on fire fighting systems in forestry and rural fire environments.

High pressure up to 425 PSI (2930 kPa) is provided to operate very long hose lays and overcome pressure losses due to large elevation changes often encountered in rugged wildland fire operations.

The higher power makes it ideal for pumping at high altitudes.

A unique feature of the BB-4® pump is the quick release pump end that is inter-changeable with ourMARK-3® pump. This standardization allows for in-field pump end exchanges eliminating long equipment down time and greatly reduces the inventory of parts at equipment service shops.
