Item Type: Fertilizer Injector Model: P2521 Material: PP Product Color: As Pictures Shown Product Size: 42x16.5cm / 16.5x6.5in Product Weight: Approx. 2131g / 75.1oz Water Inlet and Outlet Thread: G3/4 External Thread Proportion Range: 5-21% (1:4.8-1:20) Flow Range: 30-2500L/H Working Water Pressure: 0.25-5kg Continuous Operation: >100T Working Temperature: 45 Main application areas: 1. Horticulture industry: Fertilization, storage and bugs control of flowers, fruits, vegetables, etc. 2. Animal husbandry: A certain proportion of health medicine for chickens, ducks, cattle, pigs and other livestock and poultry. 3. Industrial fields: Water treatment, chemical industry, metal processing, fire fighting, etc. 4. Constant proportion dilution of special solvents such as deodorizing solvents, cooling solvents, and lubricating solvents. 5. Car washing industry, printing industry, hospital, wine industry and other industries. Application of Fertilizer Dosing Pump: 1. The variety and dosage of medicines can be changed at any time according to the needs of customers. 2. It is convenient and quick to add medicine in emergency. 3. The customer prepares the cleaning liquid by himself and adds the cleaning liquid in the channel to clean the drinking water and livestock and poultry water pipelines. 4. Solve the problems of precipitation and pollution in the water storage tank. 5. Automatic spray system, used to replace the water tank. 6. It can be used for sanitary cleaning of water pipes and sinks, water network cleaning, odor treatment, equipment, maintenance, conveyor belt cleaning, livestock and poultry drinking water treatment, acidification treatment at any time. Adjust the use ratio: 1. Predetermine the ratio of liquid additives and water according to the scale ratio on the proportional pump. 2. Counterclockwise adjustment is to increase the proportion of liquid additives. 3. Clockwise adjustment is to reduce the proportion of liquid additives. 4. The percentage of the proportional pump is calculated based on the final water output of the proportional pump being 100. Installation fixed: (standard installation and bypass installation) Standard installation: 1. Install the pump on a pipe with a threaded connection. Please carefully check the inlet and outlet arrows on the proportional pump. Make sure they are in the same direction as the water in the pipe. 2. Install a 100-120 mesh filter (not included) between the water valve and the inlet of the proportional pump. 3. The valve needs to be installed at the inlet and outlet respectively. To prevent the pump from working, the inlet valve should be closed before installation. 4. Fix the proportional pump on the wall or other facilities. 5. Install an additive container under the pump, put the tube into the container, check whether the tube is folded or bent, and make sure that the length of the tube is only a few millimeters above the bottom of the container. 6. Dosing can be done by opening the valves on both sides of the proportional pump. 7. There is a popping sound when the proportional pump starts to work. At this time, push the air release valve on the top of the proportional pump, and release the valve when a small amount of water flows out. Then ensure the normal operation of the pump. Bypass installation: When the pump does not need to be normally open, or the water pressure is higher than the technical index of the pump, a proportional pump should be installed on the bypass pipe. One advantage of this installation is that you can let water flow through when you don't turn on the pump. 1. Install the pump on a pipe with a threaded connection.
