Feature:1. Dosing device proportional pump, adopts high‑quality PP material, which is durable and wear‑resistant.2. Anti‑corrosion pump body, precise proportional scale display and adjustable dosage operation design.3. Using flowing pressure water as the power, the water pressure loss is small and no other power settings are required.4. Hydraulic power in it is used as engine to drive piston and connecting rod in the proportional pump to directly inhale and dissolve the liquid additives in the water stream.5. This device moves up and down in a cylinder to press out water and at the same time suck additives in bottom container into water stream evenly through the pipe.Specification:Item Type: Chemical ProportionerMaterial: PPModel: P2510Additive Inlet Pipe Diameter: Approx. 12mm / 0.5inWater Inlet and Outlet Thread: G3/4inProportion Range: 3%-10% (1: 33-1: 10)Flow Range: 20L/H-2500L/HWorking Water Pressure: 0.2-6bar (Kg)Continuous Operation: >100TWorking Temperature: 1-45℃Uses: Agricultural irrigation, equipment maintenance, gardening flowers, animal husbandry, environmental protection water treatment, car wash foam, food processing, industrial hygiene, printing and other industries that require constant dilution.Weight: Approx. 1836g / 64.8ozSize: Approx. 42x17.5cm / 16.5x6.9inWorking Principle of Hydrodynamics:The additive suction part and the main body of proportional pump are combined by a piston movement rod connected to the water force. This piston movement rod equipped with a backflow stop rotates in a cylinder, while pressing the water out, the liquid additives in bottom container are evenly sucked into the water through the pipe.Package List
