Application:
ZYV vacuum pumping system is composed of vacuum pump and Roots pump, widely used in vacuum smelting, welding, chemical, pharmaceutical and electric power system, particularly suitable for transformer vacuum working.
Features:
1. ZYV is quick start, big capacity of vacuum evacuating.
2. Roots pump automatically works by the controlling of relays or electrical-contact vacuum gauge.
3. ZYV equips an electrical control system and a cooling water system.
4. The vacuum pump can be Germany LEYBOLD, also the China brand vacuum pump .
