Handling Contaminated Air: The Vuototecnica VTLP Vacuum Pump
Posted by Jonathan Plumb on
The Vuototecnica VTLP series is a specialized line of rotary vane vacuum pumps engineered explicitly for harsh environments where intake air contains water condensation, solvent vapours, or chemical by-products. Unlike traditional oil-bath systems where contaminants degrade the recirculating fluid, the VTLP utilizes a highly efficient disposable lubrication system. [1, 2, 3]
Mechanical Design & Cooling
The architectural layout balances standardisation with high technical endurance:
- Independent Modular Units: The pump and the electric motor are decoupled units fixed onto a dedicated support frame. Power is transferred via an elastic transmission joint, allowing operators to utilize standard-sized electric motors rather than proprietary alternatives. [1]
- Cantilevered Rotor Design: The rotor is cantilevered-fitted directly on the motor shaft, entirely supported by independent bearings housed within the dual pump flanges. [1]
- Forced Surface Cooling: To manage operational heat, the external surface features pronounced cooling fins. Heat is continuously dissipated by a radial fan positioned between the motor and pump units. [1]
The Once-Through Disposable Lubrication Cycle
Standard vacuum pumps fail when vapours mix with the internal oil, causing emulsification, loss of lubrication, and eventual mechanical seizure. The VTLP solves this by isolating the lubrication loop: [1]

[Exhaust Stream to Factory] <── [Separator Filter] <── [Oil Recovery Tank / Exhaust]
- Fluid Storage & Monitoring: Fresh oil is housed in a transparent container featuring a magnetic level switch to prevent dry operation. [1]
- Precision Drip Feeding: Fluid is drawn into the system through adjustable drip oilers located precisely at the support bearings and suction inlets. [1, 2]
- Total Exhaust & Separation: Instead of being put back into circulation, the contaminated oil is immediately swept out of the chamber alongside the compressed exhaust air into an oil recovery tank. [1]
- Filtration & Safety: The recovery tank features an internal separator filter that suppresses acoustic noise and captures oil mists. An integrated safety valve provides automatic drainage of the exhaust oil if manual maintenance intervals are missed. [1]
Performance Specifications
The VTLP line spans minor to high-capacity industrial flow requirements:
| Model Range | Suction Flow Rate (m³/h) | Final Pressure | Electrical Configuration |
|---|---|---|---|
| VTLP 5 - 10 | 5 to 10 m³/h | High Vacuum | Single-phase or Three-phase |
| VTLP 10/F - 15/F | 10 to 15 m³/h | High Vacuum | Standard Flanged |
| VTLP 25 - 35 | 25 to 35 m³/h | High Vacuum | Three-phase standard |
| VTLP 75 - 105 / G1 | 75 to 126 m³/h | 50 mbar abs | Three-phase only |
Engineers integrating this series into process lines are strongly recommended to install a non-return check valve and an inlet filter on the suction port to prevent process backflow during shutdown. [1]
Are you designing a vacuum system for a specific application (e.g., chemical processing, thermoforming, packaging), or do you need help selecting the correct flow rate (m³/h) and motor configuration for an existing system?
