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.
