Feature:1. Proportional pumps are powered by flowing pressure water with little loss of water pressure and no other power facilities.2. Using the hydraulic power of proportional pump as engine, the piston and connecting rod in proportional pump are driven, and liquid additives are directly inhaled to dissolve in water.3. Proportional pump can adjust the proportion of additives in water according to the actual situation to achieve the best effect of additives.4. Professional manufacturing, exquisite workmanship, stable performance, low power consumption, long service life.5. The installation and use method is simple, and it can be applied to fertilizer irrigation, horticultural flowers, livestock breeding and other industries.Specification:Condition: 100% Brand NewItem Type: Fertilizer InjectorMaterial: PPInterface: G3/4inProportion Range: 1-5% (1:20-1:100)Flow Range: 12L/h-3000L/hWorking Water Pressure: 0.3-4barContinuous Work: >100TWater Temperature: 45 ° CInlet and Outlet: 25mm / G3/4inInlet and Outlet Diameter: Approx. 32mm / 1.3in, Approx. 25mm / 1.0inWeight: Approx. 1460g / 51.5ozProportional Pump Size: Approx. 35x16cm / 13.8x6.3in Adjust the proportion of use:Proportional pump can adjust the proportion of additives in water according to the actual situation to achieve the best effect of additives. The specific methods are as follows:1. Loosen the screw and remove the U-shaped adjusting lock from the upper part of the proportional pump.2. Predict the proportion of liquid additives and water according to the scale ratio on the proportional pump.Counterclockwise adjustment is to increase the proportion of liquid additives.Clockwise adjustment is to re
