Tankers (tenders) are quickly taking on additional roles in fire operations, many of them being not only capable of supplying and shuttling large quantities of water, but also serving in the roles of pumpers and rescues.
Manufacturers report they are building more tankers that can be classified as multipurpose vehicles, and departments are using these multirole tankers to handle situations traditionally dealt with by other types of apparatus.
Increased Pump Sizes
Ken Sebo, pumper product manager for Pierce Manufacturing Inc., says in his 26 years with Pierce he's seen tankers evolve from vehicles for shuttling water-featuring large tanks, small pumps, and low side compartments-to rigs carrying similar-sized water tanks but much larger pumps, hand-line crosslays, hydraulic ladder racks, hydraulic folding tank racks, and high side compartment space that might include hydraulic rescue gear.
"We are seeing pump sizes of 1,500 to 2,000 gallons per minute (gpm)," Sebo says, "and they are going on both single-axle and tandem-axle tankers. The pump house on a tanker is getting to be the same as on a pumper, and now we are putting foam systems on about 75 percent of the tankers we build, with many of them being our Husky 12 foam system for Class A and B foams."
Ryan Slane, product manager for the pumper-tanker group at KME, agrees with Sebo's assessment of the increase in pump sizes on tankers. "The old-school tanker usually had a 500- or 750-gpm pump on it, usually to move water," Slane says, "but with the larger pump sizes of 1,500 gpm to 2,000 gpm, the tanker can take on the role of a pumper if the pumper is out of service. Essentially, a tanker outfitted like that would be a sort of reserve pumper, complete with all the preconnects on a traditional pumper."

The Ocean City (MD) Fire Department recently had KME build a pumper-tanker that would complement its four KME pumpers. Chris M. Shaffer, assistant chief of the career division at Ocean City, says the pumper-tanker carries 2,500 gallons of water, 25 gallons of Class A foam, 100 gallons of Class B foam, a Waterous Advantus 6 foam system, and a 2,000-gpm pump. Shaffer says the department replaced a 1985 pumper with a 750-gallon water tank and a refurbished 2,650-gallon tanker with the new KME pumper-tanker.
"We wanted more water but the same pump module and cab configuration as on our pumpers," Shaffer says. "So the pumper-tanker has five discharges in the hosebed with 200 feet of 2½-inch hose, 150 feet of two-inch, 200 feet of 2½-inch preconnected, and two preconnected 1¾-inch hoselines of 200 feet each."
Shaffer adds that the pumper-tanker carries 1,800 feet of five-inch large-diameter hose (LDH) in its low hosebed-68 inches off the ground-which
