Diesel High Pressure Oil Pumps

The High Pressure Oil Pump (HPOP) delivers high pressure oil to the fuel injectors, which operate hydraulically. To ensure superior performance, our Diesel High Pressure Oil Pumps are the product of an in-depth remanufacturing process that includes inspection, tear down and validation, cleaning, reassembly, and testing.

Dirty Oil and Other Issues Found in The Competition's Pumps

We disassembled and inspected diesel high pressure oil pumps from the competition. Here’s what we found:

  • Paint on areas of housing that are subject to engine oil
  • Reused core components including check valve assemblies, check springs, plunger return springs, and camshaft followers
  • Rust in check valve assembly bores, stuck check balls in the housing, and dirty oil in pumps

Us vs. The Competition

All BWD® Diesel High Pressure Oil Pumps are the product of an exhaustive remanufacturing process at our TS16949, ISO9001, and ISO14001 certified facility. Throughout our process, our pumps and components are inspected, torn down and validated, cleaned, reassembled, and tested, so you can install our part with confidence. Take the process for our 37506, for example:

    We perform a 100% inspection of both front and rear bearings. If the core bearings are bad, we replace them with 100% new bearings that are the product of a line boring/honing process.

    Check Valve Assembly 

    We reassemble every check valve assembly with new sleeves, plugs, check springs, and machine-lapped flangers and plates.

    We paint the exposed topside of the pump to prevent rusting. We don't paint the rest of the housing to prevent exposing the engine oil to paint contamination.
