The name “pumper” or “engine” is derived from the function of the apparatus and from the pump that is its main feature. The primary purpose of the pumper or engine company is to confine and extinguish fires with water delivered through hose lines under pump pressure. The personnel of pumper companies usually consist of a company officer, driver-operator or engineer, and two or more hose handlers.

Standard pumpers are equipped with pumps with rated capacities of 500 gallons per minute (1,900 L/min), 750 gallons per minute (2,800 L/min), 1,000 gallons per minute (3,800 L/min) and up to 1,500 gallons per minute (5,700 L/min). Controls regulate the speed of the pump, which affects the pressure and volume of the water. Gauges and other instruments are provided for the pump operator. A pumper usually has a tank with capacities ranging from 300 gallons (1,100 L) to 750 gallons (2,800 L), called the booster tank. There may also be a smaller tank for special extinguishing agents. In many instances, the agent carried in the smaller tank is mixed with the water in the booster tank or mixed between the time the water leaves the tank and the time it reaches the nozzle.

Most pumpers have compartments called hose beds for carrying several hundred feet (meters) of 38 mm or 44 mm and in many cases 77 mm and larger sizes of hose. Reels with 19 mm or 25 mm rubber hose called booster hose are generally standard equipment. It is common for purchasers of new fire apparatus to require preconnected medium and large hose. These are lines of hose connected to a discharge outlet of the pump and designed for immediate fire fighting.

Pumpers may also carry ladders, forcible entry tools, hose connections, protective breathing equipment, portable fire extinguishers, and other tools the company uses for a variety of operations. Some pumpers may also carry equipment like hydrant wrenches, a claw tool, a crowbar, and different types of spanner wrenches. There may be some optional equipment that might be “desirable”, including a hose clamp, hay forks, and a bolt cutter.
