The Lister membrane pasture pump L 4 is specially designed for cattle and horses and is made of indestructible cast iron. Its extremely wear-resistant lifting mechanism with only two bearing points ensures a long service life. All castings are finished with a weatherproof primer and special paint, while connections and valves are corrosion-resistant. This pump works reliably even with larger suction distances and a suction depth of up to 8 meters. Compared to the L 3, the Lister membrane pasture pump L 4 is around 50% smoother. It offers a 3/4 inch external thread connection for hose and pipe and delivers approximately 0.4 liters per stroke. This robust and powerful pump is the ideal choice for water supply in pasture areas for cattle and horses.
