Thru-drive S1 none · T1 with cover · A1/B1/C3… SAE spline pads
Port location A side flanges UNC · B side flanges ISO 6149 metric
🔎 Buna or Viton on a P3? The seal-type character tells you: N or D = Nitrile (Buna-N) — standard petroleum hydraulic oil; V or T = Fluorocarbon (Viton) — high temperatures or aggressive fluids. (D and T are “wet-flange” double shaft seals.) If your nameplate is worn, send us your fluid type and operating temperature and we'll confirm the correct seals.
How to Identify Your P3 Pump
Find the full model code on the pump nameplate or housing tag — it starts with P3 followed by the displacement (075/105/145) and option codes. To get the right parts, send us:
  1. The complete model code from the nameplate (or a clear photo).
  2. Your fluid type and operating temperature (to confirm Buna-N vs Viton seals).
  3. What you need — seal kit, rotating group, control, or complete pump.

Frequently Asked Questions
What is a Parker P3 piston pump?

A compact variable displacement axial piston pump for mobile and industrial use, offered as P3075, P3105 and P3145 (75–145 cc/rev) with load-sensing and torque-control options.

How do I know if my P3 has Buna or Viton seals?

Read the seal-type character in the model code: N or D = Nitrile (Buna-N); V or T = Fluorocarbon (Viton). D and T are double “wet-flange” shaft seals. Send us your fluid and temperature if the nameplate is unreadable.

Can RestoPower source obsolete Parker P3 parts?

Yes — sourcing hard-to-find and obsolete Parker piston pump parts is our specialty. Send the full model number from your P3 nameplate and we'll locate the correct parts and quote them.
