You are looking at 2-3 weeks before I could have one in. **Q: does this pump replace the shurflo diaphragm pump 2095-223-644** A: No, very unlikely. It is important to get the exact same model that you used before. **Q: Good replacement for 2088-403-144?** A: worked for me **Q: Can this be used to pump "catchment " water?** A: This pump is by no means what would be considered a trash pump, and will not handle solids that are in the water. If it is clean and foreign material free, i think you would be okay. ## Frequently Bought Together - Shurflo 2088-343-135 Automatic-Demand Diaphragm Pump, 12VDC, 45 PSI Demand Switch, 3.0 GPM With Viton Valves, Santoprene Diaphragm, Self-Priming, 10 AMPS (Max), 1/2"-14 NPSM Port - SHURFLO (255-313) 1/2" Twist-On Pipe Strainer - SHURFLO 1434.1019 234-2926 1/2" FPT X 1/2" Barb Straight Swivel , Gray --- ## 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.ec/products/36904972-shurflo-2088-343-135-automatic-demand-diaphragm-pump-12vdc-45](https://www.desertcart.ec/products/36904972-shurflo-2088-343-135-automatic-demand-diaphragm-pump-12vdc-45) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-08-27*
