35 lb. (5-Gallon) Air-Operated Greasing Pump

Product Description This air-powered grease pump works with standard 35 lb. grease pails to deliver high-pressure lubrication. Perfect for auto shops, equipment maintenance, and industrial use. The pump uses compressed air to push grease through a 13-foot hose at pressures up to 7,500 PSI. Built tough for daily use, this system cuts greasing time by more than half compared to manual methods. You can grease 20 fittings in about 15 minutes instead of 45 minutes by hand. The 50:1 pressure ratio means every 1 PSI of air pressure gives you 50 PSI of grease pressure. Works with all standard grease types up to NLGI Grade 2. The follower plate system uses every drop of grease in the pail, so there’s no waste. Perfect for shops that grease 10 vehicles per day or maintain heavy equipment regularly.

When you set your air to 100 PSI, you get 5,000 PSI of grease pressure. This pushes through blocked fittings that manual guns can’t handle. The system maintains steady pressure even when your air compressor cycles on and off. Efficient Operation Only needs 3 CFM of air – most shop compressors handle this easily. The advanced air motor doesn’t need oil in the air line like older designs. Uses 40-72 liters of air per minute, which is about half what competing pumps need. Complete Grease Recovery The follower plate system pushes every bit of grease from the pail. No waste means you get full value from each 35 lb. container. The plate adjusts automatically as grease level drops. Professional Construction Chrome-plated pump internals resist wear Nitrile rubber seals handle all grease types Heavy-duty trolley moves easily around the shop 13-foot hose reaches tight spots without moving the pump Time and Cost Savings Labor Time Reduction Manual method: 2-3 minutes per grease fitting With this pump: 30-45 seconds per fitting Total time savings: 65% less labor time Monthly Cost Analysis (Based on 500 fittings per month) Manual labor: 25 hours at $25/hour = $625 With pump: 9 hours at $25/hour = $225 Monthly savings: $400 Annual savings: $4,800 Return on Investment Pump cost: $1,200-1,800 (typical range) Break-even time: 3-5 months 3-year ROI: 800-1,200% Frequently Asked Questions Q: What air compressor size do I need? A: Minimum 3 CFM at 90 PSI. A standard 20-gallon, 3 HP shop compressor works fine for normal use. For heavy daily use, get 5 CFM capacity. Q: Can I use thick grease in cold weather? A: Yes, but warm the grease pail to 60-70°F first. The pump handles NLGI Grade 2 grease easily when it’s at normal temperature. Q: How long will this pump last? A: With normal maintenance, expect 5-10 years. Clean the air filter weekly and replace seals every 2-3 years. Most pumps handle 500,000 cycles. Q: Does it work with my existing grease fittings? A: Yes. Comes with standard 1/8″ NPT gun connection. Works with all zerk fittings and most European types with adapters. Q: What maintenance does it need? A: Clean air filter weekly. Check hose for cracks monthly. Replace seals every 2-3 years or when you notice pressure loss. Q: Can I switch between different grease types? A: Yes, but flush the system with compatible grease when switching types. Don’t mix calcium and lithium greases. Q: How much grease does it use per job? A: Typical car needs 2-4 oz total. Truck or heavy equipment uses 8-16 oz. One 35 lb. pail services 150-200 cars. Q: Is it safe to operate? A: Very safe when used properly. Never exceed 150 PSI air pressure. Always wear safety glasses. Check hoses before each use. Complete system includes pump, follower plate, 13-foot hose, grease gun, and trolley. Air filter and regulator recommended but sold separately.
