Lincoln® PowerMaster 4 Air Motor
Strong construction is dependable and requires minimal maintenance giving you years of trouble-free use. The PowerMasters simplified modular design makes it easy to disassemble and reassemble after cleaning, upkeep and simple repairs. Ensures proper supply line pressure over long distances. The booster pump picks up low material pressure and "boosts" it back up to the desired pressure in the line. Pumping distance, pipe size and material viscosity determines number and spacing of booster pumps.
- Air valve is leak-proof, stall-proof and comes pre-lubricated
- Made with large airways keeping vents free from blockages
- All-steel body is designed to withstand pump pulsation extremes
