Equipment for Grain Treatment
SDK-7.3
It consists of a metering module mounted on the auger loader housing. The basic package includes a set of hoses for drawing liquid from the tank and returning excess liquid.
Advantages:
- can operate with all pesticides used in agriculture in the form of solutions, emulsions, and suspensions;
- installed on auger grain loaders of any model and manufacturer, allowing grain to be treated directly during loading into a vehicle or while filling a seeder;
- two spray assemblies and a common treatment chamber;
- electric diaphragm pump;
- two-stage filtration system;
- application rate is set using a low-flow regulator with a glycerin-filled pressure gauge;
- easy installation and convenient maintenance;
- supplied with a set of hollow-cone ceramic injector nozzles with different flow rates and a long service life.

Features of design:
- the recommended distance from the working-liquid entry point (nozzle) to the grain discharge point must be at least 2.5 m.
Modifications:
- SDK-7.3.220 - diaphragm electric pump 220 In;
- SDK-7.3.12 - diaphragm electric pump 12 In.
Additional options:
- 120 or 210 l working-solution tank;
- replaceable ceramic nozzles with different application rates.
