Feature: 1 No matter what occurs to the flow rate and move rate, the dosage of the solution is usually strictly proportional to the amount of water entering the kit 2 This proportional pump is made of high-quality PVC material, which is durable, corrosion-resistant and wear-resistant 3 The proportional injection device is installed in the water supply pipeline, and the flexibility can be obtained without the electric driving water pressure 4 The water pressure loss is small, and the precise proportion surroundings is not affected by the water flow 5 This product is appropriate for wastewater irrigation, package maintenance, horticultural flowers, farm animals breeding, environmental protection and water treatment, commercial hygiene, car cleaning, food processing, printing industry or other industries that should be diluted Specification: Condition: 100% Brand New Item Type: Fertilizer Injector working precept The suction additive section and the key physique of the proportional pump are connected to a piston for water stream dynamicsThe piston rod, which is supplied with anti backflow, is mixed together in a cylindrical bodyRotate and press out who, whereas passing the liquid additive within the bottom container during the tubeThe course is lightly drawn into the water circulate Model: Z3-4 (0%-4%) Material: PVC Proportion Range: 0%-4% (1:25-1:250) Flow Range: 20L/H-2500L/H Working Water Pressure: zero Inlet And Outlet Diameter: 32mm/25mm Continuous Work: >100 Days Water Flow Temperature: 4-30 ° C (39 ° F - 104 ° F) Pipeline Pressure: zero Pa (2 Pascal) (Water stress loss can get zero Pa at low circulation and 1 Pa at high flow) Water Loss: 0 Pa - 1 Pa Inlet and Outlet Thread: G3/4in Weight: Approx 1853g / sixty five Inlet and Outlet Diameter: Approx 32mm / 1, Approx 25mm / 1 Length: Approx 47cm / 18 Maximum Diameter: Approx 13cm / five Bottom Black Bar Length: Approx 20cm / 7 Model: Z3-4 (0%-2%) Material: PVC Proportion Range: 0%-2% (1:50-1:500) Flow Range: 20L/H-2500L/H Working Water Pressure: zero Inlet And Outlet Diameter: 25mm/32mm Continuous Work: >100 Days Water Flow Temperature: 4-30 ° C (39 ° F - 104 ° F) Pipeline Pressure: zero Pa (2 Pascal) (Water pressure loss can get 0 Pa at low move and 1 Pa at excessive flow) Water Loss: zero Pa - 1 Pa Inlet and Outlet Thread: G3/4in Weight: Approx 1853g / sixty five Inlet and Outlet Diameter: Approx 32mm / 1, Approx 25mm / 1 Length: Approx 47cm / 18 Maximum Diameter: Approx 13cm / five Bottom Black Bar Length: Approx 20cm / 7
