Pumps circulate the fluids an engine depends on, and a decline in any of them shows up quickly elsewhere — bearings starved of oil, or a cylinder head running without coolant. This group covers lubricating oil pumps, jacket water and circuit pumps, pre-lubrication pumps, and the transfer pumps used in the lubrication and cooling circuits. Continuous-duty gas engines commonly use large oil sumps with automatic top-up systems, since oil consumption over an 80,000 hour service interval is substantial and manual topping up would be impractical. Pre-lubrication pumps are also common, priming the bearings before cranking so the engine never starts on a dry bearing surface.
AMS Parts supplies a wide range of pumps components for MWM engines used in power generation, marine, and industrial applications. Browse the full range below, or contact us for specific requirements.
It primes the oil system before cranking so bearings are supplied before the engine turns. This removes the start-up wear that would otherwise accumulate over many starts.
Oil consumption over very long service intervals is substantial, and maintaining level automatically avoids both manual intervention and the risk of running low between services.
