Vacuum Pumps

The medical vacuum pumps are continuous duty, rotary vane, aircooled, equipped with non-asbestos vanes, having a minimum life of 40,000 hours. The 26″ Hg medical liquid ring vacuum pump systems are provided with a full recirculated oil supply. The oil separation consists of four stages of oil and smoke eliminators, capable of removing 99.9+% of oil and smoke particles from the exhaust. Each vacuum pump is driven by a 3 phase, 60 cycle, TEFC NEMA C-face, motor.

Each vacuum pump is supplied with an inlet check valve, inlet isolation valve, built-in anti-suck-back valve, inlet filter screen, oil sight gauge, oil drain valve, exhaust pressure gauge, vacuum switch, high discharge temperature switch, inlet and discharge flexible connectors and a shut-off cock for gauge and vacuum switches.

Receiver

The close coupled medical liquid vacuum pump system includes a vacuum receiver of ASME construction rated for 200 PSI MWP. The tank includes a vacuum gauge, valved by-pass and manual tank drain.

Control Panel – Basic

The UL listed control panel is supplied in a NEMA 12 enclosure and includes short circuit, single phase and thermal overload protection. Externally operable circuit breakers with a door interlock, control circuit transformers with fused primary and secondary coils, HOA switches, magnetic starters with 3 leg overload protection and reset switches are standard.

The programmable logic controller provides automatic alternation and lead-lag control with the option to select either one of the pumps as a permanent lead for periods of pump maintenance. It includes minimum run timers to prevent short cycle operation. Human machine interface (HMI) display includes pump run indication, accumulated run time and alarm conditions.

Local “Backup in use” audible and visual alarms are provided per NFPA 99. The audible alarm can be acknowledged with the “Silence” button. The visual alarm will stay on until manually reset. All controls and alarms will function even if one of the pumps is shut down for maintenance or repairs. The panel includes a set of dry contacts for connection to the master alarm.

Field adjustable control switches are pre-set to operate the lead vacuum pump between 20″ Hg and 25″ Hg. The lag vacuum pump will automatically start at 18″ Hg if the lead vacuum pump fails to operate.
