Once I get to the moderate sludge in my duck pond it stops pumping. Otherwise it works great to empty the pond, but I was looking for something to get at least some of the goop from the bottom. ## Frequently Bought Together - Allegro Industries - 9404‐04 Sludge Dewatering Pump - Apache 98138049 2" x 50' Blue PVC Lay-Flat Discharge Hose with Poly Cam Lock Fittings --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/22033763-industries-9404-04-sludge-dewatering-pump](https://www.desertcart.ec/products/22033763-industries-9404-04-sludge-dewatering-pump) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-04-25*
