DIESEL PARTS / PUMPS AND GOVERNOR COMPONENTS

# Rotary Diesel Injection Pumps

Find rotary and distributor-type diesel injection pumps by the full pump number. Bosch VE, Stanadyne DB and Delphi DPA variants are not interchangeable by appearance.

Have the original pump number and engine model handy? Those details help our specialists identify the correct family and discuss available parts or service options.

## Pump design and application

Bosch VE, Stanadyne DB and Delphi DPA rotary pump families use different designs and control features. Full assembly numbers matter.

## Match the Right Part to Your Equipment

Share the full stamped model including suffix, drive configuration and equipment application.

For an accurate review, tell DCT whether the component is an entire injection pump, a governor or an internal control part. Include the complete plate and any known differences in drive, mounting or controls.

## Service, exchange or replacement?

Compare serviceability and exchange alternatives only after model identity, condition and usage are understood.

Depending on the exact pump family and its condition, questions may involve testing, rebuilding, replacement or a verified exchange item. DCT first determines what options are actually supported; an unfamiliar used pump should not be assumed serviceable.

## Part Names and Identification

Other names include Bosch VE, Stanadyne DB2 DB4, Delphi DPA DPS, distributor pump parts. Check the pump family, complete assembly number and engine application before choosing parts.
