Corken’s positive displacement sliding vane pump, known as a Coro-Vane®, is an excellent choice for propane, butane, and  agricultural ammonia applications. The self-adjusting sliding vanes improve the pumping efficiency and help extend the life of the pump. On the standard LPG and Z-model pumps, the cam and sideplates are replaceable. The rotor, cam, sideplates, seals, and bearings are easily replaced by simply removing the pump cover. All of our propane, butane, and agricultural ammonia sliding vane pumps are equipped with a non-adjustable internal relief valve that is pre-set at the factory.

While each product group listed below is ideal for propane, butane, and agricultural ammonia, they are well suitable for numerous other liquefied gases. To find a sliding vane pump for your LPG or agricultural ammonia application, select from the following product groups.
