Medical Vacuum Systems
Medical Vacuum Systems
Central medical vacuum plant for hospitals and healthcare facilities requiring dependable capacity, automatic pump control, system monitoring and standby protection.
Vacuum Pumps UK supplies DVP CPA Triplex H medical vacuum systems for use as the central source of vacuum within hospital and healthcare medical gas pipeline installations.
Each system combines three oil-lubricated rotary-vane vacuum pumps with a vertical receiver tank, individual pump protection, isolation equipment, pressure monitoring and intelligent electrical control.
The three-pump arrangement provides controlled capacity according to demand while supporting duty sharing, standby operation and individual pump isolation for maintenance.
What Is a Central Medical Vacuum System?
A central medical vacuum system creates and maintains vacuum for distribution through a healthcare facility’s dedicated medical vacuum pipeline.
Rather than relying on individual vacuum pumps at each point of use, the complete facility is supplied from a managed plant containing multiple pumps, a receiver tank, protective filtration, control equipment, monitoring devices and isolation valves.
The controller continuously monitors system vacuum and automatically brings pumps into operation as demand changes. Vacuum is stored within the receiver, helping the system respond to short-term demand while maintaining a stable central supply.
Designed for Reliable Medical Vacuum Supply
The CPA Triplex H arrangement is designed around continuity, controlled operation, accessible maintenance and clear system monitoring.
Triple-Pump Configuration
Three vacuum pumps provide staged capacity and allow the control system to manage duty, assist and emergency operation according to system demand and the selected configuration.
Automatic Demand Control
Pumps are automatically started and stopped according to the vacuum level within the receiver, matching available capacity to the current requirements of the installation.
Emergency Pump Control
An emergency vacuum switch is electrically connected to the secondary control section to manage automatic operation of the emergency pump if an individual breakdown occurs.
Individual Pump Isolation
Each pump is provided with suction-side isolation, allowing an individual unit to be separated from the system for inspection or maintenance where the wider plant configuration permits.
Inlet Protection
Individual metal-bowl inlet filters help protect each vacuum pump from impurities that may be carried through the connected medical vacuum pipeline.
Central Monitoring
The receiver is equipped with an absolute pressure sensor and vacuum gauge, with additional alarm and control functions incorporated into the complete plant arrangement.
How the Medical Vacuum Plant Operates
1. Vacuum is generated: The rotary-vane pumps evacuate the vertical receiver and connected medical vacuum pipeline.
2. System pressure is monitored: The absolute pressure sensor continuously reports the receiver vacuum level to the control system.
3. Capacity is staged: Additional pumps are automatically brought online when demand increases and stopped when the required vacuum has recovered.
4. Pump duty is managed: The control arrangement shares operation across the available pumps while preserving the required emergency or standby function.
5. Vacuum is retained: Non-return valves help maintain vacuum within the receiver when individual pumps are stopped.
6. Maintenance is controlled: Individual suction valves allow pumps to be isolated while the remaining plant is managed according to the installed capacity and operating procedure.
DVP CPA Triplex H Medical Vacuum Systems
The DVP CPA Triplex H is based on DVP’s established three-pump central vacuum platform and has been developed specifically for medical vacuum applications according to the requirements of EN ISO 7396-1.
The system combines three oil-lubricated rotary-vane vacuum pumps with a compact vertical support and a welded, vacuum-tight painted-steel receiver tank.
Available system configurations provide nominal pumping capacities from 75 to 915 m³/h, with 300, 500 or 1,000-litre vertical receiver options according to model and required installation capacity.

Medical Vacuum Applications
CPA Triplex H systems are intended for use as central medical vacuum plant within hospital and healthcare medical gas pipeline installations.
• Acute hospital facilities
• Surgical departments
• Treatment and procedure areas
• Day surgery facilities
• Specialist clinical facilities
• Healthcare estates replacement projects
• Medical gas plant-room upgrades
• New medical vacuum installations
• Expansion of existing vacuum capacity
Selecting the Correct Medical Vacuum Plant
A medical vacuum plant should not be selected from nominal pump capacity alone. The required configuration must be assessed as part of the complete medical gas pipeline system and the facility’s operating requirements.
• Calculated medical vacuum demand
• Simultaneous usage requirements
• Required duty and emergency capacity
• Existing pipeline and plant condition
• Receiver volume
• Alarm and monitoring requirements
• Plant-room dimensions and access
• Ventilation and exhaust arrangements
• Maintenance and future expansion
Medical Gas Pipeline Design and Compliance
The DVP CPA Triplex H has been developed according to the requirements of EN ISO 7396-1 for medical vacuum applications.
The final medical vacuum installation must nevertheless be assessed as a complete medical gas pipeline system. Design, installation, validation, verification, commissioning and operational management should be undertaken by appropriately competent medical gas specialists in accordance with the applicable project standards and healthcare guidance.
Frequently Asked Questions
What is the DVP CPA Triplex H?
The CPA Triplex H is a three-pump central medical vacuum system combining oil-lubricated rotary-vane pumps, a vertical receiver, filtration, isolation equipment, monitoring devices and automatic electrical control.
What capacities are available?
Available CPA Triplex H configurations provide nominal pumping capacities from 75 to 915 m³/h, using different DVP rotary-vane pump and receiver combinations.
Why are three pumps used?
The three-pump arrangement allows the system to manage normal demand, additional capacity and emergency operation according to the selected design and programmed control sequence.
Can an individual pump be isolated for maintenance?
Each pump has an individual suction-side isolation valve. Whether maintenance can proceed while maintaining the required medical vacuum supply depends on the installed capacity, current demand and approved operating procedure.
Does the system monitor insufficient vacuum?
The system includes pressure monitoring and provision for an insufficient-vacuum alarm switch between the vacuum plant and the user installation.
Is the CPA Triplex H compliant with EN ISO 7396-1?
DVP states that the CPA Triplex H has been developed according to the requirements of EN ISO 7396-1. Compliance of the complete healthcare installation also depends on the wider pipeline design, installation, alarms, validation, verification, commissioning and management arrangements.
