Description:
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.
