Grease for Automatic Lubrication Systems
Softer grades formulated to pump reliably through long lines and metering blocks at low temperature, for machines with centralised lubrication.
Features
- Pumpability at the lowest expected temperature is the governing property, and it is why an automatic system takes a softer grade than a grease gun would.
- Line length, bore and metering block design set the minimum acceptable pumpability, so the machine's system is part of the specification.
- Bleeding and oil separation in the reservoir cause blockages, so separation stability matters more here than in a gun-applied grease.
- Changing thickener type in a centralised system means purging every line, which is why the original type should be identified first.
- Reservoir refill format is usually a keg or a pumped drum rather than cartridges.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Consistency grade | 0 or 00 | the grade that will pump through a metering block | |
| Minimum pumping temperature | -20 | degrees C | a system that will not pump in winter lubricates nothing |
| Base oil viscosity at 40 degrees C | 220 | mm2/s | still has to suit the loaded points being fed |
| Oil separation | below 5 | % after storage | separation in the reservoir blocks lines |
| Reservoir format | 18 kg keg with follower plate | has to match the pump on the machine |
