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.
