Operations Division - BFD Type I Engine
Pumper specifications were written to serve as standards for all future pumper purchases. The specifications include standardizing operations, maximizing storage space and water capacity, and meeting all regulation requirements. Listed below are factors influencing our decisions.
Power train: Detroit Series 60
Almost our entire fleet was powered by two stroke Detroit Diesels. These units will not meet future emission requirements. Detroit Series 60 power trains were chosen to power the new pumpers. Allison 700 Series automatic transmission used with older two strokes was upgraded to the Allison World transmission..
Overheating became a serious problem with previous cab-forward models. This was changed to an engine-forward design. An engine-forward design is consistent with the Series 60 model. We also changed from a transmission retarder that places heat back into the cooling system to a Telma retarder. This dissipates heat directly to the air. The change required larger alternators because the Telma uses electrical power.
Fire pump: Waterous Fire Pump
The Waterous fire pump was selected for standardization. A change was made from the more traditional pump packing to a ceramic, mechanical seal. This decision was based on reduced maintenance requirements and recent advances in mechanical seals. Pressure control will be handled by electronic governors due to versatility and ease of operation.
Water Tank: 750 Gallon Poly Tank
Poly tanks with a 750-gallon capacity will be standard for all new pumpers. This will assure all pumpers are equipped with a large enough water supply to handle an aggressive, quick attack. This tank does not require an oversized high rig or a three axle unit. A poly tank should also eliminate problems associated with metal tanks.
In order to have as much storage space as possible and still fit into the smaller, older stations, a 'rescue body' design was chosen over the more traditional look of a full tailboard and beaver tails. This allows for three high side compartments on each side, using a hydraulic ladder rack on the curb side. It also allows for increased compartment size behind the rear wheels, open to the rear. Storage space is additionally saved by placing the hard rubber line reels over the pump enclosure.
Cab Configuration: Lower Roof Line
Cab height is a problem at older stations. A lower roof line will allow for an air conditioning unit to sit on the roof. This location allows maximum cooling efficiency during warm summer months. A standard six-man side door and tilt cab design suits the needs of three-person engine companies and allows for an occasional fourth person.
