What Is the Komatsu PC200-7 Main Pump HPV95? And What's the Difference Between 708-2L-31123 and 708-2L-00300?

Quick Answer

Key Takeaways

• HPV95 = the pump model (type + size class). 708-2L-xxxxx = the order number (the exact build).
• One pump has two "names": a model name for the family, and a part number for the specific build.
• 708-2L-31123 and 708-2L-00300 are different builds of the same family, not two names for one part.
• The difference is decided by application and serial range, and can extend to build level and control settings.
• Your nameplate code — not the model name — tells you which build is correct for your machine.
• They are close relatives, but treating them as interchangeable is how wrong orders happen.

1. What Is HPV95, Exactly?

Komatsu gives its main pumps a model designation, and on the PC200-7 / PC220LC-7 it is HPV95. Read it as two pieces of information:

So HPV95 answers the question "what kind of pump is it?" It does not tell you which exact unit your machine needs, because the same model is built in several configurations. That is what the order number is for.

If you want the practical reference for this pump — weight, packing and fitment — see our companion page: PC200-7 / PC220LC-7 main pump — quick spec & fitment reference.

2. Why One Pump Has Two Names

This is the single most useful thing to understand, and it explains almost every part-number confusion:

Think of it like a car: "sedan" describes the kind of vehicle, but you cannot order parts with the word "sedan". You need the model year and trim. HPV95 is the word "sedan"; 708-2L-31123 and 708-2L-00300 are two different trims.

3. 708-2L-31123 vs 708-2L-00300, Side by Side

Put the two numbers next to each other and the structure becomes obvious:

What is shared: the component group (708) and the pump series (2L) — so these are the same family of pump, on the same machine class.

What is different: only the final block. And that final block is precisely the part that encodes which build the number refers to. This is why the two numbers are best described as "two builds of one family", not "two names for one pump".

4. So What Actually Differs?

When two builds within one family carry different numbers, the difference is driven by real things — not by catalogue decoration. In practice it comes down to these areas:

One important honesty note: you cannot reliably reverse-engineer the exact allocation of a number from the number alone. The definitive answer for a given machine comes from the manufacturer's parts data for that serial range — or from confirming your nameplate code with a supplier who holds that data. Anyone who claims otherwise from the number alone is guessing.

5. How to Tell Which One Your Machine Uses

Do not decide by model name. Use the three sources below — in this order:

Send four things and the question answers itself: the nameplate photo (straight-on), the pump from two angles, and your machine serial plate. The full range is listed under Komatsu-series hydraulic parts.

6. What Happens If You Fit the Wrong One

Because the two numbers belong to the same family, the wrong one often bolts up — which is exactly what makes the mistake expensive. What you can expect:

None of these is an obvious "wrong part" failure — they are performance problems. That is why "it fits" is not a test, and why the nameplate code is the only cheap insurance. Complete, individually tested assemblies are listed with the wider excavator hydraulic parts range.

7. Numbers People Confuse With These Two

Two more confusions come up constantly around this pump:

• 1. Neighbouring machines. Other Dash-7 Komatsu excavators use the same wider 708-2L family with their own numbers. A neighbouring model's pump number is not your pump number — see, for example, our guide to the PC210-7K (708-2L-00202), which sits in the same family but is a different build.
• 2. Same number, different supplier description. Two sellers may quote "708-2L-31123" while offering quite different products — one a new, tested assembly, the other a low-end rebuild. The number tells you the build, not the quality tier; you still have to check what is actually being sold.

In short: match the number first, then verify the product.

8. FAQ

Q1: What is HPV95?

HPV95 is the pump model designation for the Komatsu PC200-7 / PC220LC-7 main pump. "HPV" identifies the variable-displacement piston pump family, and "95" the pump size class. It is a model name, not an order number.

Q2: Are 708-2L-31123 and 708-2L-00300 the same pump?

They are the same pump family but different builds — two distinct order numbers. They are related, not interchangeable by default.

Q3: What does the "708-2L" part mean?

708 is the Komatsu component group and 2L is the pump series. Together they identify the family. The final block of the number identifies the specific build.

Q4: What is the actual difference between 708-2L-31123 and 708-2L-00300?

The difference lies in the build block, which is tied to the machine application and serial range — and can extend to build level, control settings and internal specification. The definitive allocation for a given machine comes from the manufacturer's parts data for that serial range, so confirm against your nameplate.

Q5: Can I use either number on my PC200-7?

Not safely. Even though they belong to the same family and may both bolt up, the correct build for your machine is the one on your pump nameplate (confirmed against your serial).

Q6: How do I find which number my machine uses?

Read the nameplate on the pump body, and check the machine's parts manual against your serial number. If you are unsure, send photos of the plate, the pump and the machine serial to a supplier who can confirm the cross-reference.

Q7: Does the PC220LC-7 use the same pump as the PC200-7?

Both machines use the HPV95 pump family, but the exact build depends on the model, configuration and serial range. Confirm by nameplate code rather than assuming they share one number.

Q8: Will the wrong number still fit?

Often it will bolt up, which is what makes the mistake costly. The symptom is usually performance-related — sluggish response, premature wear or lines that do not route — not an obvious fitting failure.

Q9: How heavy is this pump, and how is it packed?

About 195 kg, packed in a 53 × 53 × 81 cm case.

Q10: What should I send to have my number confirmed?

Machine model and serial number, a straight-on photo of the pump nameplate, and two or three photos of the pump itself. That is enough to confirm the correct build.
