This pump is easy to plumb to your air compressor to transfer fluid easily. The only drawback to an air operated diaphragm pump is the surging as each side pumps, with a closed system like a seal coating truck this isn’t very noticible. This pump moves product effortlessly. ### ⭐⭐⭐⭐ A+ *by on Reviewed in the United States July 23, 2024* A+ ## Frequently Bought Together - Air Operated Double Diaphragm Pump 1 inch Inlet/Outlet Pneumatic Waste Oil Transfer Pump for Chemical QBY4-25 35 GPM Dual Diaphram Polypropylene Teflon by Stainless Steel Iron 115 PSI - Duda Energy HPpvc100-025ft 25' x 1" ID High Pressure Braided Clear Flexible PVC Tubing Heavy Duty UV Chemical Resistant Vinyl Hose Water Oil --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/542333449-air-operated-double-diaphragm-pump-1-inch-inlet-outlet-pneumatic](https://www.desertcart.sn/products/542333449-air-operated-double-diaphragm-pump-1-inch-inlet-outlet-pneumatic) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-18*
