• Series 20 grease pumps include the time-proven 20 cu.in. (409,7 cm3) displacement Lincoln air motor with 2-1/2”. (63,5mm) stroke – ideal for most applications.
• Lightweight, corrosion-resistant zinc head casting design incorporates uniform wall thickness and an integral patented muffler which keeps noise level below OSHA standards without compromising performance.
• 150psi (10,34 bar) pre-lubricated air motor requires no external oiler.
• Pneumatically assisted mechanical air valve assures positive tripping.
• Springless air motor construction prevents premature pump failure due to spring fatigue.
• Double-acting design provides high pressure and uniform delivery on both up and down strokes.
• Hardened steel plunger and bushing resist abrasion and prolong pump life.
• Micro-lapped to high precision tolerance to eliminate bypassing lubricant.
• Shovel-type foot valve adds mechanical priming to normal suction.
• Handles all grades of lubricants.
