- Canning,
- meat processing plants
- Poultry farms,
- Oil industry,
- Medicine, pharmaceuticals, etc.
Purpose :
- The NVM-4 pump is designed to pump air from the vacuum chamber of packaging semiautomatic devices such as UPN (for banknotes).
The principle of action:
- The principle of operation of the NVM-4 membrane pump is based on the absorption of the pumped gas due to the periodic change in the volume of the working chamber between the membrane and the lid during the reciprocating motion of the thrust carried out using an eccentric disk planted onto the electric motor shaft.
- NVM-4 pump is well-free, environmentally friendly, practically does not require maintenance during the warranty period.
