Discription
The Oil-Lubricated Rotary Vane Vacuum System provides superior performance with minimal maintenance. The packaged system contains all necessary controls and components to meet or exceed NFPA 99 recommended guidelines. Systems are available in simplex and all multiplex arrangements. The factory packaged vacuum system consists of rotary vane vacuum pumps, pre-wired control panel, receiver, and interconnecting wiring and piping, requiring only two plumbing connections (intake and exhaust) and one major electrical connection. Medical Vacuum Systems are available in the following configurations:
|
• |
Task mounted. |
|
• |
Base mounted. |
|
• |
Stack mounted for limited space installations. |
| • |
Modular system with individual components for limited access installations. |
The vacuum pumps are continuous duty, rotary vane, oil-sealed, air cooled, direct driven units capable of continuous operation over a working range of 18" to 29" Hg. Each pump has single shaft seals and is equipped with an automatic gas ballast valve to prevent condensation of water vapor, extending the life of the oil and the system. The pump includes an integral, multi-stage oil-removal system featuring a built-in exhaust demister that removes and reclaims 99.9% of the exhausted oil. Additionally, each pump includes an exhaust back pressure gauge to indicate the need for filter maintenance and an oil sight-glass for monitoring oil level. Lubrication is provided by the integral, fully recirculating oil supply. The pump inlet is protected by means of a wire mesh screen. An internal anti-suckback valve is included to prevent oil from entering the vacuum piping network. Pump vanes, because of their construction, will provide superior heat transfer and long life. The pumps are dynamically balanced and virtually vibration free.
Each pump is driven by a direct flanged three-phase, standard TEFC motor via a pin and bush coupling. All models operate between 58-83 dBa, depending on size. Pumps require standard automotive grade SAE-30 non-detergent oil for lubrication. Synthetic oil is available as an option.
The UL listed electrical control panel is mounted in a NEMA 12 control cabinet. The standard control panel includes the following components:
|
• |
Integral circuit breaker disconnects with door interlock, across the line motor starters with three phase overload protection. |
|
• |
A programmable logic controller to cycle lead pump with each use. |
|
• |
Hand-Off-Automatic selector switch for each pump. |
| • |
Lag pump in use indicator light with horn and connection for remote annunciation. |
| • |
Hour meters to monitor factory recommended service intervals. |
| • |
Pump running lights to indicate pump in operation. |
Each system includes an ASME coded receiver rated for full vacuum service.
The system receiver includes a 2-1/2" vacuum gauge, manual drain
and 3-valve bypass. Additionally, each system includes properly sized
inlet and exhaust flex connectors, and vibration isolation pads for field
installation. The system also includes factory installed 5 micron pump
inlet filters to promote longer life. As options, the system may
be supplied with an exhaust silencer and/or bacterial filters for field
installation.
