Multi Stage High Vacuum Roots Pump Skid

A Multi-Stage High Vacuum Roots Pump Skid is a fully integrated vacuum pumping package combining multiple Roots pump stages with an optimized backing pump, vacuum isolation valves, process piping, instrumentation, electrical systems, and automated control functions on a single base frame.
The complete pumping system is customized according to the required working vacuum, continuous gas load, process gas composition, vapor content, operating temperature, and duty cycle.

Optimized Pumping Capacity: Multiple Roots stages provide high pumping speeds directly within your target operating pressure range, overcoming the throughput limitations of single-stage units under heavy gas loads.
Turnkey Integration: Complete integration of pumps, piping, sensors, valves, and electrical controls eliminates the hassle and liability of sourcing and assembling individual components on site.
Process-Specific Engineering: Metallurgy, seal types, filtration, and backing technology are selected based on whether your gas stream is dry, wet, corrosive, or dusty.
Automated Operational Control: Integrated PLC management controls system startup sequences, pressure-dependent stage activation, over-temperature protection, and safety interlocks.
Plug-and-Play Installation: Delivered fully wired and mounted on a heavy-duty structural steel frame, reducing field work to connecting power, cooling utilities, and process piping flanges.

Establish Working Vacuum under Load: Design criteria must be based on the required operating pressure during active gas release, not the ultimate limit of an empty, dry chamber.
Calculate Effective Speed: Account for flow resistance across interconnecting pipework, valves, and elbows. The pumping speed at the chamber flange is always lower than the pump's nominal speed.
Match the Backing Pump Capacity: The backing pump must handle the full throughput of the Roots stages without causing intermediate pressure buildup that could overload the system.
Mitigate Process Gas Risks:

• Wet or Condensable Vapors: Require temperature management, gas ballast, or knock-out separators.
• Corrosive Elements: Require stainless steel materials, special coatings, or inert lubricants (e.g., PFPE).
• Particulate Loads: Require upstream inlet filtration to protect precise internal pump clearances.

Vacuum Drying: Efficient moisture and solvent removal in chemical, pharmaceutical, and electrical transformer manufacturing.
Vacuum Distillation & Evaporation: Supporting low-temperature separation and solvent recovery processes.
Vacuum Degassing: Extraction of entrained gases from polymers, resins, molten metals, and oils.
Vacuum Coating (PVD/CVD): Providing rapid chamber evacuation and continuous low-pressure environments.
Vacuum Heat Treatment & Metallurgy: Furnace evacuation, vacuum brazing, and sintering operations.

Every skid undergoes rigorous testing prior to dispatch:
Dimensional & Layout Audit: Verification of flange orientation, piping alignment, and maintenance accessibility against approved 3D CAD models.
Helium Mass Spectrometer Leak Testing: Integrity verification across all vacuum welds, joints, and valve seats.
Electrical & Safety Interlock Verification: Point-to-point wiring checks, grounding continuity, and automated shutdown testing.
Full-Load Functional Test: Operational run to verify vibration levels, temperature stability, motor loads, and ultimate achievable vacuum.

To receive an accurate technical proposal, please supply the following process parameters where available:

• Target working vacuum (mbar, Pa, or Torr)
• Required pumping speed (m³/h or CFM) or chamber volume with target pump-down time
• Process gas composition (corrosive, flammable, or inert components)
• Vapor load and type (water or solvent mass flow rate in kg/h)
• Operating temperature at the inlet connection
• Duty cycle (continuous 24/7 or batch pump-down)
• Preferred electrical supply and flange standard
• Site certification requirements (CE, ATEX, UL, ISO 9001)
