Feature:

   1. No matter what happens to the flow rate and flow rate, the dosage of the solution is always strictly proportional to the amount of water entering the equipment. 

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 power can be obtained without the electric driving water pressure. 

4. The water pressure loss is small, and the precise proportion setting is not affected by the water flow. 

5. This product is suitable for wastewater irrigation, equipment maintenance, horticultural flowers, livestock breeding, environmental protection and water treatment, industrial hygiene, vehicle cleaning, food processing, printing industry or other industries that need to be diluted.

       Installation Requirements: 

     1. The water inlet and outlet of the proportional pump shall be consistent with the water inlet and outlet of the water pipe. 

2. The proportional pump must be installed with the proportional pump on top and the liquid suction pipe on the bottom. 

3. Fix the bracket of water pump to the wall or some fixed facilities 

4. Install the water pump firmly into the bracket to ensure that the small screw head on the water pump completely enters the hole on the bracket after the "click" sound.
