Flange for Scania-Cummins Common Rail Pumps

The Marbed 8240 flange is purpose-built for Cummins Common Rail injection pumps, ensuring perfect mechanical centering, stability, and compatibility with universal test benches.

Its Ø 110 mm pilot bore and Ø 140 mm bolt circle (4×M10) follow Cummins’ OEM interface standards.

The flange includes an anti-rotation system compatible with Marbed 9680-A or equivalent cradles and may be used with a Marbed oil-tight coupling for pumps requiring lubrication during testing.

Key Benefits

• Dedicated interface for Cummins Common Rail pumps

• Pilot bore Ø 110 mm / bolt circle Ø 140 mm (4×M10) – OEM geometry

• Accurate coaxial alignment on test benches

• Anti-slip / anti-rotation design for Marbed cradles

• Supports both fuel- and oil-lubricated pump architectures

• Robust machined-steel construction

Key Features

• Material: high-grade machined steel

• Centering height: 125 mm (Bosch standard)

• Centering hole (pilot bore): Ø 110 mm

• Bolt circle: Ø 140 mm – 4×M10 through holes

• Hub diameter: Ø 120 mm (cradle interface)

• Lubrication option: feed / return ports available (specifications on request)

• Anti-rotation system compatible with Marbed 9680-A cradle

• Coupling interface: oil-tight joint (included)

Operational Context

During high-pressure testing, Cummins CR pumps must remain perfectly centered and lubricated.

The Marbed 8240 flange guarantees mechanical accuracy and proper alignment with the test-bench drive shaft.

When combined with an oil-tight coupling, it allows external lubrication flow — essential for certain Cummins variants (e.g., ISB, ISC, ISL, QSB, QSC).
