Medical Vacuum Plant

CMS Medical Vacuum Plant, offer a solution to the supply of medical vacuum. Package and modular layouts are standard, with options to configure the plant to suit the project or plant room. Multiple pump systems are available as standard.

Medical Vacuum Plant General Description

• The CMS Vacuum Plant consists of two or more vacuum pumps , receiver vessel(s), duplex bacterial filter assembly, control panels and associated pipe work and valves.
• Vacuum is produced by air-cooled, oil flooded rotary vane pumps, which evacuate a BS5169 vacuum / pressure vessel. Before air is drawn into the receiver it passes through a duplex bacterial filter assembly to remove bacteria which may have entered the piped distribution system via the terminal unit. The duplex arrangement allows the plant to remain in service while the filter element is replaced. A plant control system matches the system demand with pump selection which serves to reduce energy consumption and increase the life span of the pumps.
• The plant can operate with any set of duty pump(s) to supply the duty flow, with any bacterial filter assembly on duty, using the vessel(s) or bypassing the vessels, ensuring any component can be serviced, at any time, removing the need for a plant shutdown.

Vacuum Pumps

• The vacuum pumps are identical units driven by a directly mounted close coupled wide band 380V - 415V three phase 50/60 Hz electric motor although other specific voltages and frequencies can be provided on request.
• All pumps have a minimum capacity of 200 l/m per kW corrected to NTP when the pump has equilibrated at nominal operating temperature whilst maintaining a pipeline pressure of 450 mm Hg.

Vacuum Receiver Vessel(s)

• The vacuum vessel(s) are of welded steel construction to BS 5169 and are provided with inspection access panels and manual drain. The capacity of the vacuum receiver is calculated to have a minimum water capacity equal to the Average Continuous Demand rating of the plant in litres per minute at 450mm Hg. as per NHS document C11.

Control System

• The system controls the fully automatic stop/start, duty selection and plant / pump monitoring whilst incorporating manual by-pass facilities.
• Easy to understand panel display and functions with a logical layout.

Bacterial Filters

• Duplex bacterial filters are provided complete with manual isolating valves to enable the selection of duty and standby operation.
• Each filter assembly consists of a replaceable element and a sterilisable drain trap with isolating valve and differential pressure indicator to indicate when the element needs to be replaced. When passing the design flow rate the pressure drop from a clean filter is less than 25mm Hg.
