Wittig RFW Rotary Vane Compressor / Vacuum Pump Brochure

Reliable Rotary Vane Technology

The Wittig RFW uses proven rotary vane compression technology that delivers dependable airflow and vacuum performance.

Advantages of rotary vane design include:

• Minimal number of rotating components
• Reliable long-term operation
• Reduced maintenance requirements
• Consistent vacuum performance

This design has been used for decades in tanker vacuum systems because of its durability and operational stability.

Practically Pulsation-Free Airflow

One of the key advantages of Wittig rotary vane compressors is their ability to deliver nearly pulsation-free airflow.

This steady gas flow provides benefits for many vacuum tanker operations including:

• More stable vacuum performance
• Reduced vibration within the system
• Improved operating reliability

Consistent airflow is especially important in vacuum tankers handling liquids, sludge, and industrial waste materials.

Compact Design for Flexible Installation

The RFW series is designed with compact installation dimensions, allowing easier integration into vacuum tanker systems.

Installation advantages include:

• Compact pump footprint
• Flexible mounting configurations
• Ready-to-install machine design

The unit can be mounted either standing or suspended, allowing installers to configure equipment layouts based on available chassis space.

Water-Cooled Pump Design

The RFW series uses a forced-circulation water cooling system to regulate operating temperatures.

Water cooling components include:

• Cooling pump
• Heat exchanger
• Cooling fan
• Expansion tank

This cooling approach allows the pump to maintain stable temperatures during extended operation, improving reliability in demanding field environments.

Flexible Drive Configurations

The RFW pump can be driven using several different power configurations depending on the tanker design.

Available drive options include:

• Vehicle engine auxiliary drive
• V-belt drive systems
• Hydraulic motor drive
• Flexible coupling systems
• Diesel engine drive
• Electric motor drive

Machines can also be configured for clockwise or counterclockwise rotation, allowing flexible integration into different truck layouts.

Automatic Lubrication System

The RFW pump includes an automatic lubrication system that ensures reliable oil distribution during operation.

Key lubrication features include:

• Integrated oil pump driven directly by the rotor shaft
• Large oil reservoir for extended operating times
• Dual oil sight glasses visible from multiple mounting positions

Proper lubrication helps protect internal components and maintain pump performance.

Accessories and System Components

A range of accessories are available to optimize vacuum system performance.

Common accessories include:

• Suction filters to protect the pump from debris
• Discharge silencers to reduce operating noise
• Vacuum relief valves to regulate operating vacuum
• Non-return valves to prevent airflow reversal
• Pressure and vacuum gauges for system monitoring
• Hydraulic motor drive systems
• Four-way changeover valves

These components help ensure safe and reliable vacuum tanker operation.
