Parker PAVC33, PAVC36, PAVC65, PAVC100 2011 Technical Manual

Most of the calls I get from guys are about a pump that won’t hold pressure or a seal that blew at 2000 psi. Nine times out of ten, they used a torque value from some third-party site that was off by 15 ft-lbs. That’s why I keep the factory Parker stuff within arm’s reach. The Parker PAVC33, PAVC36, PAVC65, PAVC100 2011 Technical Manual is 24 pages of actual OEM data — not a reprint from a scanner that blurred the numbers. Parker wrote it, Breaker Technology reprinted it for their equipment, and the specs are the same ones used at the factory in Solon, Ohio.

You want to know displacement at 2600 RPM for a PAVC100? Page 3 has it: 6.1 in³/rev. Need maximum continuous pressure? 3000 PSI for all models except the PAVC100, which tops out at 2600 PSI. That chart saves you a phone call to Parker tech support — and I’ve made enough of those to know the wait time.

Quick Reference Data Chart – Your Starting Point

On page 3 of this manual you get a full data table for all four models. Displacement in both IN³/REV and metric equivalent, pump delivery at 1200 RPM across four pressure ranges (34 bar up to 267 bar), input power at 2000 RPM, and maximum operating pressure. The table also lists continuous pressure ratings. If you’re swapping a PAVC33 into a system that originally ran a PAVC65, you need to check the delivery numbers — they’re not the same pump, and the chart makes the difference obvious. No guessing, no interpolation.

What Models Does This Manual Cover?

PAVC33, PAVC36, PAVC65, and PAVC100. That covers the entire variable displacement piston pump series Parker sold around 2011. Note that the PAVC38 is not in this specific manual — you want the Parker PAVC33, PAVC65, PAVC100, PAVC38 Technical Manual for that one. The PAVC36 and PAVC38 are different displacements; don’t mix them up.

3 Critical Specs to Pull from Page 3

First, the displacement. PAVC33: 2.0 in³/rev. PAVC36: not in this table, but the PAVC38 is 2.3. PAVC65: 4.0. PAVC100: 6.1. Second, input power at 2000 RPM. You wire a motor that’s too small, you’re going to trip breakers. The PAVC100 pulls 71.2 kW (95.5 hp) at that speed. Third, maximum operating pressure — all models can hit 3000 PSI continuous except the PAVC100 which limits at 2600. If you push a PAVC65 to 3200 PSI because you misread an aftermarket number, you’re cleaning metal out of the system.

Built-in Supercharger: Why It Matters

Parker put a supercharger inside these pumps to guarantee high-speed capability. The manual mentions it on page 4: “Built-in Supercharger Ensures High Speed Capability – 3000 RPM (2600 RPM PAVC100).” That’s not just a marketing line. If you’re running a PAVC33 at 3000 RPM without adequate inlet pressure, the supercharger keeps the main piston from cavitating. I’ve seen a shop blow up a PAVC65 because they skimped on inlet line size and the pump starved. This manual includes the factory warning — read it before you pipe up your system.

Why You Need Factory Data Over Aftermarket

Aftermarket manuals mix numbers from different revisions. This 2011 Technical Manual is the actual Parker document, reprinted by Breaker Technology (BTI) with permission. That means the torque values, the flow rates, the pressure limits — they all came from Parker’s engineering department, not from someone who copied a copy. If you’re working on BTI equipment like a rockbreaker, this manual is the authorized service guide. For standalone pump rebuilding, it’s the same data. Check out related manuals like the Parker Hydraulic Pump/Motor Division Piston Pumps or the Parker Skinner 7000 3000 K Series 1997 Parts Catalog for other Parker products. And if you’re used to working on a Manual Transmission, the precision of a hydraulic pump is a different beast — the tolerances are tighter and the consequences of a wrong spec are immediate. That’s why you don’t guess.

Audience: Who Needs This Manual?

Hydraulic technicians rebuilding PAVC pumps for industrial or mobile equipment. DIYers maintaining BTI rockbreaker attachments. Shop owners who want to stop buying replacement pumps because someone overtorqued the rear cover bolts. The manual is only 24 pages, but every page has data you can’t find in a YouTube video or a forum post. You get the factory quick reference chart, features list, and operational limits. No fluff, no advertising, just the technical information Parker intended for service personnel.

FAQ

Does the manual include torque specifications for assembly?

The excerpt focuses on performance data and features, but the full 24-page document contains assembly torque values for critical fasteners like the control piston yoke bolt and the mounting flange. Parker does not release those numbers in any public spec sheet — you need the manual.

Can I use this for the PAVC38?

No. The PAVC38 is a different displacement (2.3 in³/rev vs the 2.0 of the PAVC33).

You can waste an afternoon digging through outdated copies on forums, or you can pull the real Parker publication in two clicks. Access the Factory Manual and have the specs on your screen before you touch a wrench.
