Centering Mounting Flange for Common Rail Pumps

The Marbed 8155-E Centering Mounting Flange warrants the precise centering and clamping of the majority of Common Rail pumps — Bosch CP1, CP1K, CP3, CP4, Delphi, Denso, and VDO — on any standard diesel test bench.

With interchangeable reduction rings (Ø 50, 60, 68, 80 mm) and an anti-rotation interface, it simplifies the setup process while reducing tooling costs.

The flange is built from machined steel and must be installed on a Marbed 9680-A universal cradle or equivalent fixture.

Key Benefits

• Universal fixture for most automotive Common Rail pumps

• Four reduction rings (Ø 50 / 60 / 68 / 80 mm) for multi-platform use

• Compatible with Bosch CP1K and other major pump types

• Quick setup on 9680-A cradle; anti-rotation system for safety

• Reduces tooling inventory and operational costs

Key Features

• Precision-machined steel construction

• 80 mm centering hole / 120 mm hub

• Replaceable centering rings (Ø 50, 60, 68 mm) + native Ø 80 mm

• Dual anti-rotation holes for Marbed 9680-A cradle

• Works with both sides of the flange

• Designed for Bosch CP1–CP4, Delphi DFP3/DFP6, Denso HP3/HP4, VDO CR

Operational Context

For workshops requiring a universal fixture, 8155-E covers the widest range of pump geometries.

For dedicated configurations, Marbed also provides:

• 9478-CR – for Ø 50 mm hub pumps (Bosch CP1, Delphi, VDO)

• 9478-CP4 – for Bosch CP4 pumps, optimized for fast alignment

For correct torque transmission, pair 8155-E with the appropriate half coupling:

Marbed 8151, 8152, 8152-10, 9462-B, according to the pump shaft design (conical, Oldham, splined).

⚠️ Pumps with external lubrication — Bosch CP2, CP3.4, Denso HP0, Caterpillar C6.6, Cummins ISB/ISL — require dedicated flanges with oil supply fittings.
