Vogel KFGS 1-2, KFGS 5-2 2000 Technical Manual – Progressive Lubrication System Specs

I’ve pulled apart enough seized bearings to know when someone guessed on a lubrication cycle. If you’re working on a Vogel KFGS 1-2, KFGS 5-2 2000 Technical Manual system, you don’t guess. You get the factory document that tells you exactly how to assemble, bleed, and monitor the whole progressive setup. This is the original 49-page OEM manual from Willy Vogel AG, not a third-party rewrite. It covers the KFGS 1-2 and KFGS 5-2 piston pumps, the electronic control unit, progressive feeders, and every safety requirement under EC directive 89/336/EEC.

You want to know what torque to use on a high-pressure fitting? Not in here – because Vogel doesn’t use torque values on those connections – but you will find the exact fitting list, line diameters, and bleed procedures. This manual is about making sure the system meters grease or oil correctly so your equipment doesn’t fail. Let’s get into what matters.

Safety First – 1.10 Hazards Due to Electrical Current

Section 1 of the manual is all safety, and it’s not optional reading. Page references inside the PDF show 1.10 covers hazards from electrical current. The KFGS pump unit has an integrated electronic control and monitoring unit (1G 502-1). If you wire it wrong, you can fry the board or get shocked. The manual gives the color coding for the electrical connection and tells you what happens if you ignore the EMC requirements. You have to follow the wiring diagram exactly – no “close enough” on pin assignments.

Assembly and Bleeding Procedures – 3.9 and 3.10

Section 3 walks you through assembly of the main lines – dia. 6 for pump-to-feeder-to-lubrication point, and dia. 10 for pump-to-feeder-to-feeder. It lists every fitting. Then come the bleeding steps: 3.9 bleed the pump, 3.10 bleed the system. If you skip bleeding, you get air locks and the progressive feeders won’t cycle. The manual shows you exactly where to crack the lines and in what order. I’ve seen techs waste half a day because they didn’t follow that sequence.

3 Reasons to Choose OEM Documentation for Progressive Systems

First, the EC Certificate of Conformity KE 000043 is right in the front. That means Vogel stands behind the design. Second, aftermarket manuals often skip the hydraulic calculations for proportioning (section 5.4 and 5.7). This manual gives the VPKM and VPM proportioning tables. Third, the malfunction troubleshooting in section 6 is based on actual factory diagnostics – pump malfunctions, system pressure loss, feeder jams. You won’t get that from a generic “how to fix” guide.

KFGS Pump Unit – Electrical Connection and Control Monitoring

Section 4 dives into the KFGS 1-5, 3-5, 5-5 pump units. The electronic control unit can run in timer mode with or without system monitoring. Sequence of functions is explained stepwise. If you need to activate immediate lubrication (3.12), the manual tells you which relay to trigger. The pressure safety valve function (4.6) is critical – if you adjust it wrong, you’ll blow a seal. The Electrical section includes color coding for the wires so you can trace them to the terminal strip.

Progressive Feeders: VPKM and VPM Crossporting

Chapter 5 covers the feeders in depth. VPKM, VPM, VPBM – each has its own crossporting method. The manual shows both crossporting bars and tube bends. If you’re retrofitting a system, you need the proportioning data to choose the right feeder sections. This manual gives the outlet volumes for each section type. Without that, you’ll over-lube one point and starve another.

FAQ

Does this manual cover the KFGS 5-2 pump?

Yes, the manual explicitly covers the KFGS 1-2 and KFGS 5-2 piston pump with reservoir.

Are wiring diagrams included for the control unit?

The manual includes the electrical connection diagram with color coding for the integrated control and monitoring unit 1G 502-1. It does not include full schematic-level drawings, but the color code and terminal assignments are there.

What lubricants are specified?

Section 3.13 discusses lubricants and section 3.15 provides a table of lubricants. The manual does not list specific commercial brands but gives viscosity and consistency requirements for grease and oil. You cross-reference with your lube supplier.

Can I use this manual for the KFGS 3-5 pump?

The title lists KFGS 1-2 and KFGS 5-2. Section 4 does mention “KFGS 1-5, 3-5, 5-5” as pump elements, so the control and feeder information applies to the 3-5 as well, but the physical pump specs may differ. Cross-check the pump element part numbers.

Don’t trust a photocopy or a scanned PDF that’s missing pages. This is the original 2000 technical manual from Vogel, 49 pages, complete with the EC certificate. You get the same document a factory service technician would use. Access the Factory Manual and keep it on your tablet next to the grease gun.
