Liquid Ring Vacuum System
Ohio Medical partial recirculating, NFPA 99 compliant vacuum system consists of electric motor driven positive displacement non-pulsating liquid ring vacuum pumps, ASME vacuum receiver, electrical control system, and interconnection piping and wiring. The components are modularly assembled to accommodate most existing doorways and designed for serviceability. The packaged unit is factory tested prior to shipment and warranted for a period of 30 months from date of shipment or 24 months from date of start-up.
Vacuum Pump Module
Each Liquid Ring Vacuum Pump has a cast iron body, stainless steel impeller, and mechanical seals to be direct driven by a TEFC motor. Pump suction accessories include an inlet check valve, isolation valve and inlet flexible connector. Pump discharge accessories include a discharge air/water separator constructed of high density polyethylene that also serves as the partial recirculation reservoir tank. The recirculation reservoir has a two station, combination level sensor/sight glass to maintain proper liquid level. The pump discharge separator vents are manifolded, and a flexible connector is provided for job site installation to facilitate connection of vent piping to the exterior of the building.
Recirculation liquid control is interactive through a temperature sensor, with a range of 75°F to 90°F. Each recirculation liquid line will include a strainer and isolation/flow regulation valve.
The make-up water lines include a strainer, regulating valve, solenoid valve with manual priming valve and flexible connector.
