Pump barrier bag made from industrialgrade polyester mesh that protects pond and fountain pumps from leaves, algae, and other organic debris. The mesh lets water flow while keeping solids out, reducing wear and clogging and extending pump life. Key benefits and features Material: Heavyduty polyester industrialgrade mesh resists tearing and holds up to regular pond use while blocking organic matter that can cause pump wear. Size and compatibility: Approx. 16.11 x 12.18 inches (41 x 31 cm). Designed to accommodate most pump sizes—please measure your pump to confirm fit before . Secure fit: Builtin drawstring keeps the pump enclosed and prevents the bag from slipping off during operation. Performance: Large surface area around the pump reduces the risk of clogging, improves water intake consistency, and enables longer intervals between cleanings. Easy to use and maintain: Simply insert the pump, tighten the drawstring, and position in the pond or reservoir. Rinse the bag as needed to remove trapped debris. Typical applications Garden ponds and water features: Prevents leaves and pond debris from blocking skimmers and impellers on submersible pumps. Fountain and waterfall pumps: Keeps intake areas clear so flow remains steady and pumps run efficiently. Pond filtration setups and small irrigation systems: Acts as a prefilter to reduce maintenance on mechanical filters and extend pump service life. Usage tips Verify the pump dimensions against the bag size before installation. Secure the drawstring so the bag does not shift during operation. Periodically remove and rinse the bag to maintain flow. Durable, practical protection for submersible pumps that helps reduce clogs and mechanical wear without impeding water flow.
