SKF LAGG & LAGF Grease-Pumping Solutions

In modern industrial production, maintaining stable machinery and equipment operation is essential to productivity and operating efficiency. A common cause of premature damage to bearings, bearing units and moving components is incorrect lubrication: too little grease, too much grease or insufficient pumping pressure. To address this problem comprehensively, SKF has developed LAGG and LAGF grease-pumping solutions that make lubrication more accurate, safe and efficient.

1. Product specifications

Based on its technical documentation, SKF offers two main product ranges for standard 18 kg, 50 kg and 180 kg drums.

For large production lines, heavily loaded equipment or harsh working environments, SKF LAGF provides a professional, high-performance grease-pumping solution. The range includes manual, pneumatic and electric versions to meet diverse industrial requirements.

A key advantage of SKF LAGF grease pumps is their high working pressure and stable delivery rate, which distribute grease evenly to complex lubrication points, including positions requiring high pressure. Certain models integrate a pressure gauge or flow-control mechanism, helping operators monitor and adjust lubrication accurately.

SKF LAGG GREASE PUMPS – A RELIABLE SOLUTION FOR DAILY MAINTENANCE

SKF LAGG is a portable grease-pump range designed for simplicity, flexibility and ease of use and is suitable for routine maintenance in factories and production workshops. Despite its compact design, LAGG provides the pressure and durability needed to deliver grease accurately to each lubrication point.

One notable advantage of SKF LAGG grease pumps is their precise control of grease output, which helps prevent under- or over-lubrication, a common cause of premature bearing failure. Robust construction supports reliable operation in industrial environments while making the unit convenient to use in confined or hard-to-reach locations.

2. Advantages of SKF grease pumps

• LAGF range (manual pumps):
  • Tested and approved for all SKF greases.
  • Easy to install and use.
  • Ensures absolute cleanliness when transferring grease from a drum to a grease gun, preventing contaminants from entering.
• LAGG range (mobile pumps):
  • LAGG 18M (manual pump): High pressure of 500 bar; suitable for pumping grease, oil and other fluids. Its mobile design makes it easy to relocate.
  • LAGG AE (pneumatic): A proven, durable design. A robust trolley makes 50 kg and 180 kg grease drums easy to move, and the pump connects simply to the workshop compressed-air system.

3. Industrial application locations

SKF LAGG and LAGF grease pumps are widely used in factories and maintenance workshops:

• Industrial manufacturing plants, including cement, steel, paper and food production.
• Automotive and heavy-vehicle maintenance and repair stations.
• Mining and construction equipment.
• Remote, hard-to-reach lubrication points requiring high pumping pressure.
• Technical-material stores, using LAGF for clean grease transfer.

4. Benefits for users

• Cost savings: An intelligent follower-piston design uses nearly all the grease in the drum and minimizes waste.
• Longer equipment life: Clean grease supplied through the LAGF range helps bearings operate longer and prevents contaminant-related damage.
• Safety and cleanliness: Reduces direct contact between the operator and lubricant and keeps the work area clean.
• Higher productivity: Pneumatic LAGG models make high-volume grease delivery faster, easier and less labor-intensive than conventional manual pumping.
