Feature: 1. ACCURATE AND EFFECTIVE: Adopt reciprocating dynamic sealing technology, this dosing pump has higher accuracy. Unique cylinder block and piston motion area design ensures more uniform and effective mixing of liquid and medicine. 2. APPLICATION: Suitable for animal health, food safety and hygiene, irrigation, metal processing, nutrient delivery systems, printing, car wash, water treatment, dilute solutions or other industries that require a certain proportion of dilution. 3. EASY TO USE: Clear scale, automatic proportional dosing, accurate measurement can be changed at any time to change the dosage and fertilizer varieties, without changing the irrigation system or control scheme, easy to operate. 4. WATER POWERED: Water powered fertilizer injector, no electricity is needed. It uses volumetric proportioning, ensuring that the chemical mixture remains the same regardless of variations in pressure and flow. The water flow rate will be reduced when going through the fertilizer injector. 5. EFFICIENT AUTOMATION: This pump utilizes an automatic proportional pump, eliminating the need for manual mixing and distribution, thus significantly enhancing production efficiency. Specification: Item Type: Fertilizer Injector Product Material: Plastic Product Specification: R2504 (0.4?4percent ) Ratio Range: 0.4percent ?4percent (1:25?1:250) Working Pressure: 0.2?5kg S/cm3 Inlet and Outlet: 25MM/25MM Product Use: Livestock breeding proportion pump doser, industrial disinfection, agricultural irrigation.
