0445010050 Bosch CP1 Common Rail Fuel Pump 3-Plunger Design

Product Description

We supply 0445010050 as a CP1 common-rail high-pressure fuel pump for Mercedes-Benz and Dodge Sprinter applications using the 2.7 CDI OM612/OM647 engine family. For a commercial-vehicle buyer, the important point is not simply the vehicle badge: the pump number and engine configuration have to agree. We therefore treat 0445010050 as a part-number-controlled replacement and ask buyers to send the number on the existing pump before we confirm an order.

The supplied product information describes a three-plunger CP1 configuration with pressure-control hardware and a maximum working-pressure figure of up to 1400 bar. In a common-rail system, the high-pressure pump supplies fuel to the rail, while the rail and injectors handle pressure accumulation and controlled injection. Bosch describes the high-pressure pump as the component that delivers fuel into the connected rail under high pressure.

Product Snapshot

Application & Compatibility

We use the following application scope as the working reference for this SKU: Mercedes-Benz / Dodge Sprinter 2.7 CDI with OM612 / OM647 diesel engines. This does not mean every vehicle within a broad model family is automatically compatible. Before we confirm an order, we compare the complete pump number with the engine/application details supplied by the buyer.

Why we position 0445010050 for Sprinter service

For workshop buyers, this pump is most relevant when a Sprinter 2.7 CDI has a confirmed pump-related pressure or delivery problem and the replacement number has been verified. The OM612/OM647 application is a useful identification starting point, but it is not enough on its own to guarantee interchangeability. We recommend comparing the pump label, mounting arrangement, hydraulic connections and electrical/metering configuration before purchase.

Technical points we check before shipment

Our product team checks the supplied pump against the ordered part number and reviews the requested application. For units going through our bench-testing process, the inspection focuses on leakage/sealing, pressure build-up or stability and fuel delivery. The purpose is to identify a pump that is mechanically and hydraulically suitable before it leaves our facility.

What buyers should send us

For a fast B2B quotation, send the pump number 0445010050, a clear photo of the identification label, the engine code, the vehicle model/year where known, and any OE or cross-reference number already on your records. If the pump is being replaced after a low-rail-pressure fault, also tell us what tests have already been completed so we do not assume that the pump is automatically the failed component.

Replacement and commissioning notes

Before installation, the low-pressure fuel supply, filter condition and fuel cleanliness should be checked. After installation, the fuel system should be correctly primed and the rail-pressure system checked for leaks and stable operation. If the engine still shows low pressure, hard starting or unstable running, the diagnosis should also cover the fuel filter, low-pressure supply, metering control, rail and injectors rather than replacing additional parts without testing.

Our B2B supply support

We support repair shops and distributors with new and remanufactured options, neutral export packaging, flexible MOQ and technical matching assistance. Our goal is to reduce wrong-part orders, especially when several CP1 pumps have similar external appearances.

What We Check Before Shipment

• Exact part-number and label identification against the purchase order.
• Product condition: new or remanufactured, as quoted.
• Visual condition and obvious sealing/interface issues.
• Hydraulic inspection or bench testing where included in the supplied product/QC process.
• Packaging and labeling suitable for international B2B shipment.

For products sold as new or remanufactured, we follow our internal identification, visual inspection, sealing and hydraulic testing workflow. Where a bench-test record is required, we can provide the applicable inspection information for the supplied unit. We do not use a test claim as a substitute for checking the exact pump number and application.

Ordering Information

For a quotation, please send the exact pump number, quantity, engine code, vehicle/application, OE or cross-reference number if available, required condition (new or remanufactured), destination country and a clear photo of the existing pump label when possible. This information helps us reduce wrong-part shipments.

FAQ

Q: Is 0445010050 suitable for every Sprinter 2.7 CDI?

A: No. We recommend confirming the complete pump number and engine/application information before ordering. A vehicle model alone is not sufficient for a precision common-rail pump.

Q: What information should I send for a quotation?

A: Send the pump number, pump label photo, engine code, vehicle model/year and any OE or cross-reference number you have.

Q: Can you supply a remanufactured version?

A: Yes, where available. We confirm the condition and warranty terms for the exact unit offered before shipment.

Q: What should be checked after installation?

A: Prime the fuel system correctly and check leakage, rail-pressure behavior and engine operation. If a pressure fault remains, continue system-level diagnosis.

Our Company & Technical Responsibility

We are Guangzhou Zhuohang Auto Parts Co., Ltd., a professional supplier of diesel common-rail fuel-system components. We work with overseas repair shops, vehicle maintenance businesses, machinery service companies and distributors. Our role is not only to supply a part number; we help buyers verify the pump identity, application, condition and replacement requirements before shipment.

Our technical-sales responsibility is to help buyers identify the correct product, explain the relevant common-rail system considerations and communicate the condition and inspection scope of the unit supplied. We do not describe an aftermarket or remanufactured part as a genuine Bosch product unless genuine status has been verified.

Warranty & After-Sales

We provide a 12-month warranty for applicable products under our stated warranty terms. For a warranty claim, we normally need the order reference, part number, installation information, fault description and supporting diagnostic evidence. Our team can help distinguish a pump-related issue from problems elsewhere in the fuel system.
