The Type 4 engine trades a smaller pump and less hose for a 50% larger tank. It is required to carry a minimum of 750 US gallons (2,800 L; 620 imp gal) of water, but only pump 50 US gallons per minute (3.2 litres per second; 42 imperial gallons per minute) at a pressure of 100 pounds per square inch (690 kPa).

The oil pressure generated in most engines should be about 10 psi per every 1000 revolutions per minute (rpm), peaking around 55-65 psi. [2] Local pressure (at the crankshaft journal and bearing) is far higher than the 50, 60 psi &c. set by the pump's relief valve, and will reach hundreds of psi.
Oil pump from a scooter engine. A gear pump uses the meshing of gears to pump fluid by displacement. [1] They are one of the most common types of pumps for hydraulic fluid power applications. The gear pump was invented around 1600 by Johannes Kepler. [2] Gear pumps are also widely used in chemical installations to pump high-viscosity fluids.
A hydraulic ram pump, ram pump, or hydram is a cyclic water pump powered by hydropower. It takes in water at one " hydraulic head " (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate.
The volume of a mechanical pressure washer is expressed in gallons or liters per minute, [1] often designed into the pump and not variable. The pressure, expressed in pounds per square inch, pascals , or bar , is designed into the pump but can be varied by adjusting the unloader valve or using specialized nozzle tips.
Ordnance crest "WHAT'S IN A NAME" - military education about SNL. This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958.
The Unit Pump system [1] is a modular high-pressure diesel injection system, which is closely related to the unit Injector system, and is designed for use in commercial vehicle diesel engines. [ 2 ] The systems use an individual injection pump mounted on the engine block for each cylinder so it is primarily designed for OHV or "cam in the block ...
Output of this engine was 210 hp (157 kW) at 4000 rpm and 315 lb⋅ft (427 N⋅m) of torque at 2600 rpm. Five Thunderbirds with pre-release supercharged Essex V6s were supplied to the Arizona Highway Patrol in 1988 for road testing, even though the supercharged engine never became part of an official police package.
