PP-20 Air-Operated Double Diaphragm Pump, Polypropylene, 1/2 in

Key features

• 48 L/MIN MAX FLOW PLATFORM — Shared R-20 Series performance rating for pneumatic fluid transfer. Actual flow depends on viscosity, suction conditions, backpressure, piping and available air supply.
• 7 BAR MAX WORKING PRESSURE — Common pressure class for the R-20, RS-20 and PP-20 platform, with 1/2 in fluid connections and a 1/4 in air inlet.
• AIR SUPPLY MATTERS — Published maximum air consumption is 350 L/min with a 400 cpm maximum cycle rate and 0.15 L displacement per cycle; insufficient air can reduce output and cause startup problems.
• THREE BODY-MATERIAL ROUTES — Choose aluminum, stainless steel or polypropylene according to the installation environment and the complete wetted-material compatibility required by the process.
• PLAN FOR SETUP & MAINTENANCE — Suction-side sealing, check valves, clean fluid passages and post-use flushing are important for priming and reliable operation.

PRONA R-20 Series air-operated double diaphragm pumps are 1/2 in pneumatic fluid-transfer pumps for paint, coating and industrial process applications. The family shares a verified 48 L/min maximum flow, 7 bar maximum working pressure, 1/2 in fluid connections, 1/4 in air inlet, 400 cpm maximum cycle rate, 0.15 L displacement per cycle and 350 L/min maximum air consumption. Choose R-20 aluminum, RS-20 stainless steel or PP-20 polypropylene according to the required body material and the complete wetted-material compatibility of the process. Maximum solids size is intentionally omitted because current PRONA documents conflict between 2 mm and 3 mm. Confirm the final U.S. thread standard, diaphragm, ball, seat, seal, temperature and fluid compatibility before use.
