The industries:
- LVZ and alcohol plants,
- Canning,
- meat processing plants
- Poultry farms,
- Oil industry,
- Medicine, pharmaceuticals, etc.
Purpose :
- The NV-4 pump is designed to create a vacuum in a working chamber with a volume of not more than 6 DM. sq. In various vacuum and vacuum and final machines.
The principle of action:
- The principle of operation of the vacuum NV-4 pump is based on mechanical absorption and pushing air due to periodic changes in the volume of the working chamber.
- Equipped air sequentially passes through a working block and an oil tank, passing through the filter, it is cleaned of oil vapor.
