ARO Ingersoll - Rand high quality pneumatic lubricating free motor with pneumatic gear pump as a special configuration for diesel engine Pre-lubrication system.
　　The pump adopts the double circular arc and sine curve of gear tooth-type, running without sliding friction, long service life. And also pump operates smoothly, no phenomenon of trapped fluid, high efficiency. Use pneumatic motor as pump’s driving power would be able to use same compressed air resource with air starter. The pneumatic motor also makes the pump more adaptable to high temperature, humidity, much grease environments. Pneumatic pre-lubrication system, with its advanced features becomes Marine diesel engine popular configuration choice.
Performance characteristics：
·Pre-lubrication and Engine starting use same compressed air resource; easily to gets association or independent operation for both of configuration.Pneumatic motor drive is ·the best solution for marine use which eliminated creepage, burning and other unsafe factors.
·The machine has compact structure, small volume, and adjusts oil supply pressure and flow can be online stepless speed regulation, it is suitable for various specifications of the engine emissions.
