JILONG | Basic Double Action Hand Pump | 29P390

The Jilong Avenli Basic Double Action Hand Pump (Model 29P390) is a high-efficiency manual inflation system designed for larger-scale outdoor recreational gear. Standing at a robust 36 cm (approx. 14 inches) in height, this pump is optimized to provide more substantial air displacement compared to compact 30cm models, reducing the total number of pumping cycles required for large inflatables. It serves as a rugged, portable utility tool for camping, beach days, and backyard pool maintenance, requiring no electricity or batteries. Constructed from a heavy-duty, impact-resistant polypropylene hull, the internal piston assembly is designed to handle the increased stress of larger-volume filling. Like the smaller series, this model uses a dual-action piston system that forces air out on both the upward and downward strokes, effectively doubling the speed of inflation. The base features wide, textured stabilization foot supports that anchor the pump firmly to sand, dirt, or patio tiles, allowing for powerful leverage. The reinforced, non-kinking accordion hose provides the reach necessary to access deep-set valves on air beds and pool floats, ensuring a complete, tight seal for quick and efficient inflation.
