Features 1Dosing device proportional pump, adopts highquality PP material, which is durable and wearresistant. 2Anticorrosion pump body, precise proportional scale display and adjustable dosage operation design. 3Using flowing pressure water as the power, the water pressure loss is small and no other power settings are required. 4Hydraulic 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. 5This 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. 6The up and down movement is repeated to achieve the effect of uniformly and continuously adding additives to the flowing water. Specifications Item Type: Chemical Proportioner Material: PP Model: P2510 Additive Inlet Pipe Diameter: Approx. 12mm / 0.5in Water Inlet and Outlet Thread: G3/4in Proportion Range: 3%-10% (1: 33-1: 10) Flow Range: 20L/H-2500L/H Working Water Pressure: 0.2-6bar (Kg) Continuous Operation: >100T Working 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 / 64.8oz Size: Approx. 42x17.5cm / 16.5x6.9in Working 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 flow 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 flow through the pipe.
