HIGH FLOW HAND PUMP: Manual Pump uses 2M thick transparent PVC pipe. Resistant to oil, high temperature and corrosion, the large diameter hose allows the pump to pump liquid faster, with a pumping speed of 10L/min. Note: The liquid you want to pump must be higher than the incoming bucket. The connection end should be placed in the liquid. EASY TO USE: Simply squeeze the pump 2-3 times to extract the liquid. The built-in check valve can effectively prevent liquid from flowing back. Note: The arrows marked on both ends of the pump body make it easy to identify the direction of water flow. MULTIFUNCTIONAL PUMP: Lightweight and portable hand pump, very suitable for various vehicles and equipment without anti-theft nets, such as lawn mowers, brush cutters, hedge trimmers and low pressure fuel supply systems. WIDE USE : Perfect and safe transportation of fuel, oil, gasoline, diesel, water or non-corrosive liquids for ships, vehicles, lawn mowers, tractors, motorcycles, water beds, aquariums and other liquid siphons. PACKAGE CONTAINS: You will get 1 x hand pump, 1 x 2M hose, 2 x clamps and 1 x control valve. The control valve is used to adjust the size and change the water flow, and it also serves as a link.
