COMPLETE MANUFACTURER REFERENCE / 5 FAMILIES
Modern controls call for careful evidence.
Names such as DHP and K-series can appear in specialist component conversations, but a short series code is not an interchange guarantee. With electronically managed fuel systems, reliable identification and engine-side testing are especially important before any pump is removed.
Have a pump identification plate, an engine model or a photograph? You have enough to start the conversation. We will help review the information and discuss available service or parts options for the exact component, without assuming every model is serviceable.
Make a better decision before ordering parts
First, photograph the entire component and any information plate. Then record the engine make, model and serial number, plus the equipment it powers. A pump that looks similar is not automatically calibrated or fitted the same way.
Second, write down the complaint in ordinary language: no-start, difficult starting, intermittent loss of power, a fuel leak, contamination, or a concern discovered during another repair. Include what a qualified technician has already checked. That context can prevent an unnecessary component purchase.
Third, contact DCT before sending a component. Our team will review the information, confirm whether an appropriate service or parts path is available and provide receiving instructions for any approved shipment.
Family-by-family guidance
These are all the pump families named under CONTINENTAL / SIEMENS VDO in DCT’s source register. Each note focuses on getting the component identified, separating a symptom from a diagnosis, and making the next step simpler. A family being listed is not a promise of available inventory, parts interchange or repair acceptance.
CONTINENTAL / SIEMENS VDO / PUMP FAMILY
DHP1
A truck that cranks too long, a machine that loses pulling power, or a rail-pressure fault after another repair can all send an owner searching for a pump number.
DHP1 is a distinct Continental / Siemens VDO label. Pair the name with the engine application, electronic system information and every number on the body before discussing a possible replacement or service scope.
These systems require fuel-supply, pressure-control, rail and injector evidence to be considered together; a pressure code on its own is not a pump diagnosis.
Before you remove, replace or ship it: Ask the shop to record commanded versus measured rail pressure where available, fuel-filter condition, supply restrictions and any contamination findings. Do not open high-pressure lines during operation.
Explore DHP1: identification, symptoms and next steps
Before you decide it needs a pump
A rail-pressure complaint can involve the supply side, control system, injectors or high-pressure pump. A fault-code description alone does not identify which component has failed.
For a diagnostic technician, the expensive decision is often whether a supply problem, rail control issue or component failure justifies removing the DHP1 assembly. Measurements from the machine can protect against a costly guess.
Identify this CONTINENTAL / SIEMENS VDO family confidently
Numbers and suffixes within the “DHP1” naming family can reflect different assemblies. Treat the full stamped string and exact engine installation as the reference, not a generic online CP/HP-series listing.
When the record is hard to find: For electronically controlled diesel systems with closely related names, manuals, old component tags and equipment records may use different numbering. Keep the source of each number in the inquiry rather than silently combining uncertain identifiers.
The observations that help the most
- Record rail-pressure demand versus actual pressure under an OEM-approved diagnostic procedure, where supported.
- Document low-pressure fuel delivery, filter condition and any evidence of water or metallic contamination.
- Keep injector leakage or return-test findings together with the pump report; a high-pressure pump cannot be judged in isolation.
Safety and accuracy: Common-rail systems can retain dangerously high pressure. Never loosen or open high-pressure lines to troubleshoot a running system; follow the engine maker’s depressurization instructions.
Three questions worth asking before authorizing work
- Is the reported pressure problem present at crank, idle or loaded operation?
- Were supply-pressure or restriction measurements obtained with the correct procedure?
- Has any technician documented contamination before dismantling the system?
From concern to a practical next step
Start with what the operator noticed, add the facts an independent shop has already measured, and photograph the full unit plus every number. DCT can then discuss whether identification help, additional engine-level testing, a supported component evaluation or a parts inquiry is the appropriate next conversation. The exact work and receiving location are confirmed before anything is shipped.

DHP2
When an engine struggles under load, it is tempting to order the first high-pressure pump whose photo looks familiar.
DHP2 should not be treated as a cosmetic revision of DHP1. The full installed unit number and fuel-system configuration establish the relevant technical discussion.
These systems require fuel-supply, pressure-control, rail and injector evidence to be considered together; a pressure code on its own is not a pump diagnosis.
Before you remove, replace or ship it: Ask the shop to record commanded versus measured rail pressure where available, fuel-filter condition, supply restrictions and any contamination findings. Do not open high-pressure lines during operation.

DHP3
An expensive common-rail diagnosis deserves more than a replacement guess made from a single fault code.
DHP3 completes the DHP1-DHP3 naming progression in this register. Actual fitment, control arrangements and test methods must be confirmed from the complete unit, not assumed from the sequence.
These systems require fuel-supply, pressure-control, rail and injector evidence to be considered together; a pressure code on its own is not a pump diagnosis.
Before you remove, replace or ship it: Ask the shop to record commanded versus measured rail pressure where available, fuel-filter condition, supply restrictions and any contamination findings. Do not open high-pressure lines during operation.

K10
When you cannot find your pump in a typical online catalog, you have not reached a dead end; you have reached the point where identification matters most.
K10 is one of the short Continental / Siemens VDO series identifiers that can be lost in a generic component search. Photograph the entire tag and note the engine management system before sourcing a matching unit.
The family name is a useful signpost, not a complete technical specification. On less-common systems, a wrong assumption can create more downtime than the original fuel complaint.
Before you remove, replace or ship it: Send the clearest photo of the complete pump, every visible number, the engine/equipment serial and a short description of symptoms before discussing parts or shipping.

Before you decide it needs a pump
This reference often appears in older or specialist equipment where an exact number is more valuable than a broad internet search. Model-family naming alone is not a reliable service specification.
When electronically controlled diesel systems with closely related names has to earn its keep, the first good result is a reliable identity for the K10 unit. That saves time chasing an attractive but potentially incompatible replacement.
Identify this CONTINENTAL / SIEMENS VDO family confidently
Because “K10” is a short designation, include the CONTINENTAL / SIEMENS VDO maker name in searches and keep the entire identification plate in any inquiry. A short letter code is easily mistaken for unrelated equipment terminology.
When the record is hard to find: For electronically controlled diesel systems with closely related names, manuals, old component tags and equipment records may use different numbering. Keep the source of each number in the inquiry rather than silently combining uncertain identifiers.
The observations that help the most
- Take a sharp close-up of all numbers and a wider photograph showing the complete housing, drive and controls.
- Record the equipment make, engine model and serial, plus any manual or historical parts-book number.
- Describe the complaint, storage history and any previous modifications or substituted parts.
Safety and accuracy: Avoid ordering a similarly named pump or assuming service acceptance until the exact assembly has been identified.
Three questions worth asking before authorizing work
- Is the identification from the original plate or an old parts invoice?
- Has the pump been replaced, rebuilt or re-tagged previously?
- Which engine number can be used to verify the correct configuration?

K16
An obscure pump designation is worth preserving instead of replacing with a guess from an unrelated model.
K16 is retained separately from K10 because those labels alone do not demonstrate interchangeability. Capture the complete part number and the original engine installation for a meaningful review.
The family name is a useful signpost, not a complete technical specification. On less-common systems, a wrong assumption can create more downtime than the original fuel complaint.
