NAVAC NRD16 PFPE 3PH - Dual Storage Oil Sealed Rotary Vane Vacuum Pump

The NRD16 series vacuum pump is a high speed, motor direct drive dual-stage oil sealed rotary vane pump. It is a basic model used to obtain vacuum and be used to pump inactive gas within the scope of low vacuum and a small amount of non-condensable gas.

This pump is suited for coating, refrigeration, freeze drying, sterilization, instruments analysis, leak detection equipment, heat treatment metallurgy, etc. It can be used as a backing pump for roots pumps as well. It has a reasonable structure design for long failure-free operation. It features high reliability, high flow rate, low ultimate pressure, and low noise level. The pump has no oil spray, no leak, and is easy to maintain.

Oil Included
High quality mineral oil provided standard with the pump. All models can also be prepped for PFPE.

Principle of Gas Ballast

The controllable gas (generally dry air at room temperature) is admitted into the pump chamber. It is mixed with pumped vapor during the gas compression process.

This increases the percentage of non-condensable gas such that the partial pressure of the vapor being pumped is below its saturated vapor pressure when the exhaust valve opens. The vapor is then discharged from the pump without liquefaction. The more vapor contained in the pumped gas, the more dry air is required.

NAVAC NRD16 Parts:

1. Two-shift adjustable gas ballast valve satisfies the different requirements of condensable gas to be exhausted.
2. Dual automatic anti-sucking back design protects vacuum system from oil pollution when pump stops running and needs to be easily restarted.
3. Forced oil circulation system ensures stable running of the pump.
4. Integrated cylinder structure and pin connection convenient and accurate for maintenance and inspection.
