Off-Highway equipment can have a very hard life. Equipment is often "rode hard and put up wet" as they say, but most of the wear on the heart of your work horse can be prevented. Whenever an engine is shut down, especially for long periods of time, such as while sitting in a leasing yard or between jobs, vital oil that is needed to protect the bearings and other moving parts of the engine drains back to the sump. Even after a short down time oil films can become very thin leaving the stage set for a bearing to "wipe". If direct metal-to-metal contact occurs during startup your engine is never the same. The damage caused by the first wipe will generate more friction and heat leading to progressive damage that soon requires an expensive rebuild.
Prelubing your engine every time you start it is the best way to be sure that oil is always protecting its moving parts. Compare the cost of a prelube system with the cost of engine overhaul and down time. It just makes sense to protect your expensive engine.
Simple is a funny idea when applied to pump design. Many people comment on how simple Varna pumps are. A simple design that also performs at a high level is anything but simple to achieve.
