How to Read a Parker Hannifin Pump Model Number (Series Guide & Parts Finder)
Parker Hannifin is one of the largest hydraulic manufacturers in the world, and its pump model numbers pack a lot of information into a short code. If you are sourcing a replacement or a seal kit, reading that code correctly tells you the series, displacement, control type, and porting so you order the right part the first time. This guide breaks down the main Parker Hannifin pump families and how to decode them.
Parker Hannifin pump series at a glance
Parker organizes its hydraulic pumps into several families, each with its own naming logic. The most common series RestoPower supports include:
- P1 / PD – medium-duty axial piston pumps for mobile and industrial machines.
- PVP – variable-displacement piston pumps with pressure compensation.
- PAVC – compact variable-volume piston pumps for industrial power units.
- PVplus – high-performance variable pumps for demanding industrial duty.
- F1, F2, F3 – fixed-displacement piston pumps common on trucks and mobile equipment.
- F11 / F12 – bent-axis fixed and variable pumps and motors.
How to read a Parker pump model number
Parker codes are read left to right. The leading letters identify the series, followed by fields that define displacement (cc per revolution or cubic inches), the control or compensator style, shaft type, port arrangement, and rotation. Because a single family can span dozens of variants, transcribe every letter and digit from the nameplate exactly — a single character often separates two otherwise identical pumps.
Where to find your Parker model number
The model number is stamped on the nameplate or cast into the pump housing, usually near the mounting flange or on the end cover. If the tag is worn, measure the shaft, mounting pattern, and port sizes and note the number of bolts — those dimensions let us cross-reference the correct Parker piston pump or Parker seal kit.
Parker Denison — a related brand
Denison is now part of Parker Hannifin, so many Denison T6/T7 vane pumps and Gold Cup piston pumps are cross-referenced within the Parker catalog. If your unit carries Denison branding, start on the Denison parts page instead.
