You need a replacement hydraulic pump for your excavator. You call your Chinese supplier and they ask for the OE number. But the nameplate on your old pump is completely worn off — rust, oil, and years of heavy use have erased it. What do you do?

This is the number one reason South American buyers get the wrong hydraulic pump. And it costs them $2,500 in wasted parts plus 6-8 weeks of equipment downtime.

Here is how we solve this problem — without requiring you to know any OE numbers.

"CAT 320D" is not a single machine. It is a family of machines built over a decade, and different production years use completely different hydraulic pumps.

• CAT 320D (2006-2012) uses one pump design
• CAT 320D2 (2013-2017) uses a completely different pump
• CAT 320 GC (2010-2014) uses a lower-spec pump
• CAT 320 Next Gen (2017-present) is a new platform entirely

Most suppliers just list "compatible with CAT 320D" and ship whatever their catalog says. When it does not fit, they blame the buyer.

Each manufacturer has its own OE number format, and even small variations mean a completely different pump:

• Caterpillar uses 7-9 digit part numbers like 226-7559 or 248-6355
• Komatsu uses 8-digit codes like 708-2H-00100 or 708-1L-00330
• Hitachi uses numbers like 4465413 or 9218040
• SANY uses mixed formats like 60131896A or 090800000034
• Hyundai uses codes like 2162-3410A or 21N2-17010

Even when you have the OE number, different suppliers interpret it differently. One supplier is 226-7559, another is 2267559 — and you might get a completely different pump.

Many excavators in South America have been repaired multiple times with aftermarket or rebuilt pumps. The current pump may not match the original factory specification at all. Without visual identification, even the correct OE number can lead to the wrong replacement.

This is the fastest and most reliable method. You do not need to be a hydraulic engineer — you just need your smartphone.

Take 3-5 photos of your old pump and send them to us:

• Overall front view showing the general shape and size
• Mounting flange showing the bolt pattern
• Port connections including suction port, pressure port, and drain port
• Nameplate or label if any part is still visible
• Any visible part numbers stamped on the housing

Our engineering team cross-references these visual cues against our database of over 3,000 excavator hydraulic pump models and returns the exact match within 2 hours.

Every excavator has a machine nameplate, usually on the cabin door frame or boom base. It contains:

• Exact model designation such as PC200-8M0 not just PC200
• Serial number
• Manufacturing year
• Engine model

Send us a photo of this nameplate, and we look up the factory-installed hydraulic pump specification for your specific machine.

If the pump nameplate is completely unreadable, we can identify the pump using the engine serial number to access the factory build specification, which includes the exact hydraulic pump model installed at the factory.

As a final check, we verify the match against your excavator is hydraulic system parameters including working pressure, flow rate, and displacement. This cross-check catches any remaining mismatches before shipping.

Send us photos via WhatsApp — that is our fastest channel. We respond in real-time, not 14 hours later. Include your excavator model if you know it, and any part numbers you can see.

Our engineering team, not sales reps, analyzes your photos using visual comparison against our pump database, bolt pattern matching, port configuration identification, housing shape analysis, and cross-reference with manufacturer specifications.

Within 2 hours, we send you the exact pump model identified, the OE number, technical specifications including displacement, pressure rating, and flow rate, a photo of the actual pump we will ship, and an all-inclusive DDP price delivered to your door.

You confirm the match. If you are unsure, we discuss the specifications until you are comfortable. We do not ship until you approve. Once confirmed, we handle quality inspection, packaging, air freight, customs clearance, and delivery to your workshop.

Our database covers over 20 brands and over 3,000 models:

• Caterpillar CAT: over 120 models, over 800 OE numbers mapped
• Komatsu: over 90 models, over 600 OE numbers mapped
• Hitachi: over 70 models, over 500 OE numbers mapped
• SANY: over 60 models, over 400 OE numbers mapped
• Hyundai: over 50 models, over 350 OE numbers mapped
• Doosan: over 45 models, over 300 OE numbers mapped
• Volvo: over 40 models, over 280 OE numbers mapped
• Kobelco: over 55 models, over 380 OE numbers mapped
• XCMG: over 50 models, over 320 OE numbers mapped

After over 5,000 pump identifications in 2024 alone, we have seen virtually every identification challenge including pumps with completely worn-off nameplates, machines with modified hydraulic systems, universal pumps that do not fit any specific model, and aftermarket pumps that replaced the original.

When you send photos, they go to our technical team. Our engineers have hands-on experience with hydraulic pump disassembly and reassembly, access to manufacturer technical databases, monthly training on new pump models and updates, and direct relationships with factory technical support.

Out of over 5,000 identifications in 2024, 98.5 percent were correct on the first attempt. For the remaining 1.5 percent, here is what happens:

If the pump we identify and ship does not fit your excavator, we cover return shipping costs to China and send the correct replacement immediately. No questions asked, no blame game.

Before we ship, we send you photos of the actual pump, technical specification sheet, pressure test results, and dimensions for comparison with your old pump. You verify everything before the pump leaves our warehouse.

A Komatsu PC200-7 hydraulic pump failed after 8,000 hours in Minas Gerais, Brazil. The nameplate was completely gone — rust and hydraulic fluid had erased everything. The owner took photos of the pump body and sent them via WhatsApp. Within 2 hours, we identified it as a 708-2H-00100 pump and shipped it via air freight DDP. Eight days later, it arrived at the workshop in Belo Horizonte. Perfect fit. Running for 11 months with zero issues.

A dealer in Bogota, Colombia needed a pump for a Hitachi ZX200-3. Three different suppliers gave three different OE numbers. None of them asked for photos of the old pump — they just looked up ZX200-3 in their catalog. We asked for photos, cross-referenced the bolt pattern and port configuration, and identified the correct pump as 4465413 with a specific revision code. It was different from all three previous suppliers. It fit perfectly. The customer had wasted $4,000 and 3 months before finding us.

A CAT 330D in Santiago, Chile had been modified by a previous owner with a larger pump for a high-flow attachment. When the pump failed, the standard 330D pump did not work. The fleet manager sent photos showing the larger mounting flange and additional drain port. We identified it as a modified system pump and sourced the correct larger-displacement unit. We were the only supplier who caught that modification.

Identifying a pump from photos requires technical knowledge of hydraulic pump design, access to manufacturer databases, experience with real-world identification challenges, and engineers who understand the nuances of different model variants. Most suppliers just look up the excavator model in a catalog and ship whatever the catalog says. When it does not fit, they blame the buyer.

Use your smartphone. Good lighting helps, but even rough photos work. We have identified pumps from photos taken in dark, muddy conditions.

Send the photos to our WhatsApp number. Include your excavator model if you know it, the symptoms of what is happening with the pump, and any part numbers you can see.

We identify the pump, send you the specifications and a photo of the actual unit, and provide an all-inclusive DDP price delivered to your door.

Review the identification, ask any questions, and approve. We handle the rest — quality inspection, packaging, air freight, customs clearance, and delivery to your workshop.

You do not need to know the OE number. You do not need to be a hydraulic expert. You do not need to risk getting the wrong pump.

Take a photo. Send it to us. We handle the rest.
