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.\u003c\/p\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43356732129489,"sku":"BW-B0HK8YNDD8","price":900.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/61neByix1CL._SL1254.jpg?v=1790980081","url":"https:\/\/belmontwarehouse.com\/products\/r-20-air-operated-double-diaphragm-pump-aluminum-1-2-in","provider":"Belmont Warehouse","version":"1.0","type":"link"}
