Pumping assembly flammable liquids
This chapter describes pumps up to and including the GPM. For information on larger capacity pumps, see Chapters 6 and 7. The 1-quart-per-stroke dispensing pump NSN is used chiefly to transfer lubricating oil.
The pump can be attached to a gallon drum or a gallon tank. This pump as shown in Figure consists of a pump assembly, a suction pipe, and a discharge tube. The piston is raised and lowered by a gear-and-rack mechanism which is driven by a crank handle. Turning the handle to make one complete stroke pumping assembly flammable liquids the piston delivers 1 quart of product.
The handle must then be returned to its original position before more product can be delivered. The pump has an adjustable stop so that it does not deliver too much or too little product. Product is delivered through a nozzle, which is positioned to connect with an adjustable swing arm return tube.
The return tube pumping assembly flammable liquids excess product drain back into the drum through a channel located in the pump base. If the work area is not under cover, the pump suction pipe and the drum vent plug pumping assembly flammable liquids be tightened securely and protected with a waterproof cover when the pump is not in use. This keeps water from seeping through the drum openings and contaminating the product. This pump is used chiefly to transfer lubricating oil from gallon drums to smaller containers.
The gallon-per-minute GPM dispensing pump NSN is used to transfer automotive gasoline, kerosene, fuel oil, and pumping assembly flammable liquids fuel. The pump transfers these products from and to various containers.
The GPM pump as shown in Figure consists of a pump assembly, a suction pipe, a discharge hose, and a valveless nozzle. When not in use, the nozzle is placed in the nozzle bracket on the discharge pumping assembly flammable liquids.
The pump suction pipe must be tightened securely to the drum vent plug and protected with a waterproof cover when the pump is not in use.
The GPM dispensing pump NSN is used to transfer fuel from gallon drums or gallon, skid-mounted tanks. This fuel can be pumped directly to equipment fuel tanks. This unit as shown in FigureFigure, consists of a hand-driven, reciprocating pump; a suction stub assembly; a hose assembly; a nozzle; and a brace assembly.
The pump body is mounted to the suction stub assembly, which fits into the 2-inch opening of the drum. The suction stub assembly includes a telescoping suction pumping assembly flammable liquids and a threaded bung adapter.
The pump is operated by a push-pull action of the lever; the lever drives the piston within the pump, forcing fluid to the pump outlet. The pump discharges through a foot length of 1-inch hose and a standard nozzle with a mesh, wire-cloth strainer. A grounding wire equipment with alligator clamp and bonding plug is attached to the nozzle to permit electrostatic bonding between the nozzle and other equipment.
The brace assembly is attached to the top of the pump and to the chime of the drum to hold the pump securely during pumping operations. The pump suction pipe of this pump must be tightened securely to the drum vent plug and protected with a waterproof cover when the pump is not in use.
The GPM pump is used to transfer fuels from gallon drums or gallon, skid-mounted tanks direct to equipment fuel tanks. The GPM pumping assembly pumping assembly flammable liquids used for bulk transfer of flammable liquids. A GPM electric pump used with the tank and pumping assembly flammable liquids unit is described in Chapter The GPM pumping assembly as shown in Figure consists of a pump and engine assembly mounted on an oval aluminum base.
The pumping assembly is equipped with a carrying handle. It and fits into a rectangular aluminum box that can be used as pumping assembly flammable liquids carrying case. The box has pumping assembly flammable liquids oval inner compartment to hold the mounting base of the pump and engine assembly.
An outer compartment holds the coiled lengths of hose, the drum-unloader suction stub, the ground rod, and the muffler. The pumping assembly flammable liquids nozzles are stored in mounting brackets on the underside of the box lids.
The pumping assembly must be bonded and grounded before operation. TMs and contain information on the operation and maintenance of GPM pumping assemblies. The GPM, portable pumping assembly is used to transfer fuel from one bulk storage tank to another and from storage tanks, tank cars, and tank vehicles to gallon metal drums, gallon collapsible drums, vehicles, and aircraft. With the suction stub attached to the suction hose, the pumping assembly can be used to empty gallon drums.
When equipped with a hose and fitting kit, it can be used to fill 5-gallon fuel cans and refuel vehicles. The pumping assembly is also issued as part of the can and drum cleaning machine.
The GPM pumping assembly is used to transfer fuel from storage tanks, tank cars, and tank vehicles to smaller capacity containers. These containers include 5-gallon cans, gallon drums, and gallon collapsible drums.
The GPM pumping assembly as shown in Figureconsists of a gasoline-engine-driven pump mounted on a frame, a rigid-wall suction hose, two discharge hoses, and two pumping assembly flammable liquids operated hose nozzles.
The unit must be grounded before operation. TM gives information on the operation and maintenance of the GPM pumping assembly. The GPM pumping assembly is used to transfer fuel from storage tanks, tank cars, and tank vehicles to 5-gallon cans, gallon drums, and gallon collapsible drums. Pumping assembly flammable liquids can also be used to refuel vehicles and aircraft. The GPM pumping assembly as shown Figuregasoline- or diesel-engine driven is mounted on a two-wheel trailer.
The assembly can be moved by a towing vehicle using the attached tow bar. However, it must be towed for only short distances at speeds not exceeding 20 miles per hour on surfaced roads.
If the pumping assembly must be moved for a long distance, it should be loaded on a cargo vehicle or flatbed using a pumping assembly flammable liquids device with at least a 2,pound capacity. The assembly must be moved on these vehicles. The gasoline-engine-driven pumping assembly is covered pumping assembly flammable liquids TMs, and The diesel-engine-driven pumping assembly is covered in TM When GPM pumping assemblies are used with the 4-inch hose line outfit, they are equipped with a pressure regulator to control the flow of product through the hose line.
It moves fuel from the source of supply to pumping assembly flammable liquids tanks and from the tanks to the dispensing equipment. The pump may also be used with any of the collapsible tanks now used by the Army and with the 4-inch hose line outfit assault hose line. Sign In Sign Out. Enter Your Email Address.
