Berarma 01 PLP 05 Technical Manual – What a 28-Year Tech Expects

I’ve seen more vane pumps ruined by guessing than by wear. If you’re working on a Berarma 01 PLP 05 variable displacement vane pump, you don’t have room for error. The displacement is 16 cm³ (0.976 in³), max working pressure 120 bar (1740 psi). This 15-page Technical Manual is the factory-issued document that shows you the exact installation procedure, adjustment settings, and dimensional data. No aftermarket summaries, no translated guesses. This is Berarma’s own PDF.

General Description & Technical Data – Pages 4-5

Page 4 starts with a general description of the pump family and the mechanical pressure compensator design. The Technical Data on page 5 gives you the key numbers: displacement, working pressure range, and rotational speed limits if you need to size the drive. You won’t find any fluff here – just the specs Berarma used during factory testing.

Ordering Code & Characteristic Curves – Pages 6-7

Page 6 breaks down the ordering code so you can identify exactly which variant you have. The characteristic curves on page 7 plot flow vs. pressure at different compensator settings. That graph is critical if you’re trying to match the pump to a hydraulic system without over-speeding or cavitating.

Dimensions and Combined Pumps – Pages 8-11

Page 8 has the overall dimensions – mounting flange patterns, shaft key size, port locations. Pages 9 through 11 cover combined pump configurations (tandem or piggyback setups). If you’re stacking pumps on the same drive, you need these drawings to avoid interference and port mismatch.

Installation Instructions: Page 13 Matters

Installation norms start on page 12 in Italian, English version on page 13. This is the section beginners skip – then wonder why the pump makes noise or leaks after 50 hours. The manual specifies pipe routing, filtration level required, and minimum oil viscosity. Follow page 13 to avoid voiding the warranty. For related industrial equipment, check the Drogobych Crane КТА-16, КТА-25, КТА-28 2004 Installation Manual and the Injectocean Diablo, Murciélago, Defender, Discovery, Freelander Technical Manual if you work on those machines.

Settings Adjustments: Page 14 Pressure Compensator Tuning

Page 14 covers the regulator settings – the mechanical compensator adjustment screw and the order of lock-nut torque. Don’t touch that compensator without reading this page. Over-tightening changes the pressure setting by more than 100 psi per quarter turn. Get it wrong and the pump either deadheads or bypasses too early.

3 Reasons to Choose OEM Documentation Over Aftermarket

First, aftermarket reprints often omit the Italian warning notes that contain legal liability clauses – Berarma includes them for a reason. Second, the characteristic curves are scanned from factory originals, not redrawn by someone who approximated the data. Third, the installation instructions on page 13 include specific notes about shaft seal orientation that no third-party manual mentions. The Minsk MMVZ-3.11212 Technical Manual – Factory Specs follows the same philosophy of original print quality.

What Torque Values Are Listed?

This manual does not include torque specs in the provided excerpt – the technical data section (page 5) focuses on hydraulic parameters. For mounting bolts, the installation norms (page 13) reference clamping force guidelines but the actual torque is application-dependent. Always consult the pump’s nameplate data or Berarma directly if you need specific values. For general reference, see the Manual Transmission article for understanding bolt torque in rotating assemblies, or Manual Transmission for common fastener classes.

How many pages is the Berarma 01 PLP 05 Technical Manual?

15 pages, including bilingual Italian/English content.

Does it cover combined pump configurations?

Yes. Pages 9-11 are dedicated to combined (tandem) pumps, with dimensional drawings and ordering codes for multi-pump setups.

What torque values are specified for the compensator locknut?

The manual does not list a numeric torque value in the provided section. Page 14 instructs to tighten the locknut after adjustment, but the precise torque depends on thread size – refer to the pump nameplate or Berarma support.

Is the Italian version different from the English version?

The Italian and English text are on facing pages or alternating sections. The warning notes (page 1-2) are identical in content. The technical data and curves are language-free. Both versions are included in the PDF.

If you’re about to install or adjust a Berarma vane pump, stop working from memory. Access the Factory Manual – it’s the only document that guarantees you’re using Berarma’s own test data and instructions. 15 pages, immediate access, no aftermarket nonsense.
