The PM70A air-cooled vacuum pump from Moro USA is primarily used in small industrial applications. It weighs in at 309 pounds, has 29 psi positive pressure capability, 322 cfm free airflow and a suggested tank size between 1,000 to 3,000 gallons. The pump has a cast iron body with visual inspection ports and employs radial rotary Kevlar vanes to provide vacuum/pressure and a direct-feed sealed oiling system. Its large, open-ported manifold reduces noise and air friction. The cantered rotor produces greater vacuum and pressure by preventing air from slipping past the vanes. High-quality Viton oil seals and low rotating speed leads to longer pump life. It can be easily mounted on a truck frame and connected to the truck drive system. It can also be delivered in preassembled pump packages for special applications. 800/383-6304; www.morousa.com.
