New Fuel Pump Generation Improves Reliability for MAN 32/40CD Engines

With implemented IMO Tier III regulations and the associated shift to a wider range of fuel oils including – from 2020 – ultra-low-sulphur fuel oils, maintenance professionals increasingly face greater challenges concerning fuel injection during engine operation. This includes the risk of lacquering of the fuel-pump plunger and resultant sticking and malfunction, which the Mk3 pump efficiently and reliably reduces. The new design implements a sealing ring inside the pump barrel which significantly reduces lacquering and all associated side-effects. Similarly, the new design now avoids the mixing between fuel and lube oil, which enables their re-use and minimises the need for their disposal.

“MAN 32/40CD fuel pumps can be upgraded through a simple change of existing pump element units, regulators and drives, and parts that you change during a standard maintenance said Stefan Eefting, Senior Vice President at MAN PrimeServ. “We think this a very economical solution and believe that the exchange of the Mk3 injection pumps is an easy and efficient one that allows the re-use of the original Mk1 pump housings – it is the next-level evolution.”

MAN PrimeServ states furthermore that customers investing in the new Mk3 pump will likely see a return on investment within two years.

Torsten Dehn, responsible Product Manager at MAN Energy Solutions, said: “Having identified potential problems associated with the imminent, increased diversity of fuel types, MAN has redesigned the MAN 32/40CD injection pump and established a new, state-of-the-art standard. We are setting a new benchmark in reliability, which is absolutely unique in the market, and the popularity of the 32/40 engine means that there is huge potential for this innovation.” MAN will manufacture the pump completely in Germany with MAN PrimeServ responsible for its distribution.
