About this item

• Feature: 1. Water Pressure Start: The fertilizer injector is installed directly on the water supply pipeline, and the water pressure is used as the power to work, without the need to power on or start the motor. 2. Main Features: Accurate automatic dosing ratio is not affected by water pressure fluctuations. The amount of solution injected is proportional to the amount of water flowing into the pipeline, and the external adjustment is flexible and convenient. 3. Multi Function: Complete quantitative dosing and mixing functions, continuous proportional injection, precise proportional tracking adjustment, and automatic uniform dilution. 4. PP Shell and Anti Corrosion Body: The outer shell is made of high quality pp, which is wear resistant and anti ultraviolet, and is not easy to age. The pump body adopts anti corrosion design to ensure the availability of solution and increase the service life. 5. Wide Range of Application: Integrated design, high accuracy, long service life, the liquid doser dispenser is suitable for many fields such as horticulture, animal husbandry and industry.

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. 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.

Package List: 1 x Fertilizer Injector3 x Accessory Circle1 x Tube With Filter 1 x Bracket1 x English Instruction Card1 x Wrench Note: 1. Make sure that the container for liquid additives is not empty when using the automatic proportional pump!2. Air release valve: When the proportional pump is started for the first time, the air release valve needs to be pressed for a few seconds to exhaust the air that already exists inside. During this process, a small amount of water may flow out. After expelling the air, close the valve quickly.3. When installing and using, make sure that the filter device is installed at the inlet of the proportional pump.4. If the working resistance becomes larger during use, lubricating oil (not included) should be added to the piston to increase the service life.5. After the proportional pump is used, clean water should be used to reduce corrosion and prolong the service life of the proportional pump.6. The accessories are in random colors.7. The filter is provided by the customer.Maintenance: After the proportional pump has been working for two years, the two sealing rings on the piston need to be replaced. Unscrew the upper cover of the proportional pump to take out the piston, and remove the two large and small seals on the piston with a vise ring. It is recommended to put the two seal rings together, soak them in 90 degree water for 2 minutes, and then install them on the piston by hand.
