All industrial pumps are equipped with an adjustable internal relief valve and feature self- adjusting sliding vanes and vane drivers to improve pumping efficiency. And, maintenance is simple. Removing the pump cover gives full access to the rotor, cam, sideplates, seals, and bearings. Drive options include gear reducer, V-belt, and hydraulic. Suitable liquids include but are not limited to aviation fuel, fuel oil, lube oil, solvents, and liquefied gases such as LPG, ammonia, and carbon dioxide
Many LPG (propane & butane) and agricultural ammonia piping systems do not have ideal conditions for net positive suction head (NPSH). As a result the poor NPSH conditions lead to excessive pump maintenance. Since reciprocating compressors are only exposed to vapors, poor NPSH conditions are not a factor. Many LPG and agricultural ammonia pressurized tanks such as tank cars and buried tanks have top unloading connections. A reciprocating compressor is the perfect solution for transferring liquids in this type of application
Most Corken vertical LPG reciprocating compressors have single packed piston rods and none offer oil-free gas compression. The only exception is the model D891 which has two sets of packing (one V-ring and one segmented) but it is not oil free. Single packed, non oil- free compressors are typically used in non-corrosive and non-toxic applications where oil- free service and leakage containment are not critical. Typical applications include propane, butane, agricultural ammonia, and natural gas.
