Advantages : Continuous Duty
Arrow engines are designed for continuous duty 24 hours a day, day after day. Arrow's heavy duty design features a heavy flywheel, a governor speed control, and a pressurized full flow lubrication system to assure continuous operation.
Oilfield Tough
Over 75,000 Arrow engines are powering pumping jacks in oilfields all over the world. Many of the original engines built in the 1940's are still running today.
Gas Fueled
Arrow engines run on a variety of low BTU gases; natural gas, wellhead gas, methane, butane or propane. The single cylinder Arrow engines can also be equipped with a fuel lift pump and will operate on gasoline.
Economical Operation
Studies performed show operating costs for Arrow engines can be as low as half the cost for equivalent HP electric motors. Since every area is different, a detailed comparison specific to your costs is warranted.
Easy Maintenance
Arrow engines are designed for easy, quick field maintenance. The oil level can be checked and adjusted while the engine is running. Easy access enables replacing piston rings and wet cylinder sleeves in the field, and Arrow parts are interchangeable from the first model made.
Ignition
Starfire Solid State Ignition Systems are standard for Single Cylinder engines.
Arrow Improvements:
Improvements to the Heavy-Duty C-Series Engines since May 1977 (most all are retrofitable to earlier models using current kits):
· Heavy steel fabricated sub-base
· Full flow oil system with spin-on filter
· Portable starter added to sub-base
· Bronze crankshaft gears for C-46 through C-106
· Arrow oil filler added to engine (ASP-1)
· O-ring modified rocker shaft plugs
· Reliable stainless steel braided oil lines
· Ball rod ends standard on all Arrow engine models
· Stainless steel water filler added as standard (ASP-3A)
· Vibration-free cross braced radiator shells
· Common muffler made standard on C-Series engines
· Lifting eyes added to facilitate engine handling
· Newly increased engine horsepower with Impco 100 and 200 carburetors
· All Arrow Engines are either electric 12-volt ring gear starting
· Instrument panel for starter switch, receptacle, oil pressure gauge and shut down
· Cylinder head accepts Impco carburetors without using cross flange adapter
· Improved ring gear starter mounting on new flywheel
· Added QD hub to flywheel for safety in de-mounting
· Latest trochoidal oil pumps standard
· Oil pressure bypass valve included in oil pump assembly
· Optional renewable oil filter available
· A wiring harness is used to combat weather hazards
· Starfire ignition is standard (C.D.I. for long life) and operates in the rain
· Redesigned breather system to improve crankcase ventilation and reduce emissions
· Solderless pressure condensing radiators with steel top tanks, bottom headers
These engines are made in such a way that you can count on us buying it back from you as a core when you're done with it!
Typical fuel usage: Why are Arrow single cylinder engines so fuel efficient?
On oilwell pumping applications multi cylinder engines suffer a great disadvantage because they cannot be applied at, or even near, their full load power. Neither can multi cylinder engines be operated at a uniform rate of speed due to a lack of flywheel inertia. Hence the Arrow engines, properly applied, can always attain much better fuel economy than multi-cylinder engines on oilwell pumping. Usually this fuel savings is 40%.
This means Arrow engines will not only do a better job on oil well pumping units than multi-cylinder engines, but will use less fuel also.
Example:
A C-96 running around the clock at 570 RPM, using refinery natural gas for fuel requires approx. 200,000 BTU/hr. Refinery natural gas is approx. 1100 BTU/cu.ft. so:
200,000/1100 = 181.81 cu.ft/hr or: 181.81 x 24 = 4363.44 cu.ft per 24 hr day
However, an engine producing less than maximum HP for a give RPM will use slightly less fuel. A C-96 produces approx. 19 HP @ 570 RPM So: if your HP requirement is 14.25 HP, the C-96 is producing 75% of max. HP arrived at by way of 14.25/19=75%
This means that a C-96 @ 75% load uses 10.5 cu.ft of 1100 BTU gas per HP hr or 149.6 cu. ft per hr (10.5 x 14.25 = 149.6 cu.ft/hr or 3591 cu. ft per 24 hrs.
