How to Read a Vickers & Eaton Pump Model Number (Complete 2026 Decoder Guide)

If you need to order a replacement pump, seal kit, or spare part, everything starts with one thing: correctly reading your Vickers or Eaton pump model number. These alphanumeric codes look intimidating, but every character tells you something specific about the pump — the series, displacement, port configuration, shaft type, and pressure setting. This guide breaks the code down field by field so you can identify exactly what you have and find the right parts the first time.

Where to find your Vickers / Eaton model number

The model number is stamped or printed on the pump's nameplate, cover, or housing boss. On vane pumps it is usually on the flat boss near the cover; on piston pumps it is on the nameplate on the pump body. If the tag is missing or worn, you can often read a cast number directly on the housing. Write down the complete code — every character matters when cross-referencing parts.

Reading a Vickers vane pump code (V10, V20, VQ series)

Vickers vane pumps use a code where the leading letters and numbers identify the series and nominal displacement. For example, a code beginning with V10 or V20 tells you the pump family, while the following characters define the ring size (flow), port position, shaft key, and rotation. Common fields include:

• Series – V10, V20, 25V, 35V, 45V, and VQ high-performance variants.
• Ring / cartridge size – sets the displacement (GPM) per revolution.
• Shaft type – keyed, splined, or tapered.
• Port position & rotation – usually noted by a letter such as L (left/CCW) or R (right/CW), viewed from the shaft end.

Reading a Vickers / Eaton piston pump code (PVB, PVH, PVQ series)

Piston pump codes are longer and fully define the pump's features across a fixed-length string. In many Vickers/Eaton piston pump models, the first numbers represent displacement per revolution, followed by fields for compensator type, port orientation, shaft, and control options. Because these codes can run 20+ characters, transcribe every digit and dash exactly as shown on the nameplate.

What each field controls (quick reference)

• Displacement – the physical size / flow of the pump.
• Pressure setting – maximum rated pressure or compensator setting.
• Shaft & mounting – flange pattern and drive interface.
• Rotation – clockwise or counter-clockwise from the shaft end.
• Seal material – Buna-N (standard) or Viton (high-temp / chemical).

Frequently asked questions

What if my Vickers pump tag is missing?
You can often identify the pump from cast numbers on the housing, the shaft and port configuration, and the mounting flange. Send us photos and measurements and we can help match it.

Are Vickers and Eaton pumps the same?
Eaton acquired the Vickers brand, and the product lines now also fall under Danfoss. Model codes carried over, so a legacy Vickers code and its Eaton equivalent typically reference the same pump.

Do you sell aftermarket and OEM-equivalent parts?
Yes. We stock OEM-equivalent seal kits and components that meet or exceed original specifications, backed by a 2-year warranty.
