Gardner Denver oil-sealed screw vacuum pump – Elmo Riestchle S-VT series.
Today, many factories have shifted to using… central vacuum pump system to supply vacuum to the entire production line, replacing the previous model of using multiple small pumps at individual machine locations.
This solution helps to reduce initial investment costs, optimize maintenance and operating costs, simplify system management with saves installation space, while ensuring high stability throughout the entire production process.
Gardner Denver SVT Series – A New Standard in Performance and Reliability
In 2020, Gardner Denver introduced a screw vacuum pump SVT Series – an optimal solution for centralized vacuum systems requiring high performance and continuous operation.
With more 70 years of experience in industrial vacuum technology, Gardner Denver has developed a new generation of Elmo Rietschle S-Series SVT1500, SVT2000, and SVT4000, integrating a variable frequency drive (VFD) for load-based speed control..
Oil-lubricated screw technology with proven oil lubrication, combined with a new-generation screw design, helping to improve overall performance with increase operational durability.
In particular, the intelligent variable frequency drive design allows energy savings of 50% or more. compared to traditional fixed-speed vacuum pump systems, while reducing the load on the electrical system and optimizing long-term operating costs.
Next-Generation Gardner Denver – Elmo Rietschle SVT Vacuum Pumps
The SVT Series vacuum pumps are developed based on more than 70 years of Gardner Denver’s experience in industrial vacuum technology. The new-generation design delivers outstanding performance, stable operation, and maximum energy efficiency for centralized vacuum systems
High-efficiency compression element design
High quality compressor from reputable manufacturer Ingersoll Rand.
A larger air-end diameter and lower rotational speed help improve efficiency, reduce wear, and enhance reliability
A wide flow range from 20–100% allows optimized performance at all load levels, reducing unnecessary energy consumption
Intelligent oil tank system
Three-stage oil–air separation ensures superior oil separation efficiency.
High oil retention capacity, minimizing oil consumption during operation.
Simple design, easy maintenance and replacement of parts.
Stable direct drive
The high-performance IE3 motor, cooled by a fixed-speed fan, ensures optimal cooling even when operating at low speeds.
The compressor head and motor are rigidly coupled, precisely aligned, and mounted on a three-point anti-vibration support, which reduces vibration and increases equipment lifespan.
Dual-zone heat separation design
Two independent temperature control zones.
A dedicated cooling zone for the drive motor
A high-temperature zone for the oil system prevents moisture condensation while extending the service life of the oil, filters, and compression element bearings
Integrated intelligent variable frequency drive (VFD) control
The integrated variable frequency drive with PID control maintains a stable vacuum level according to actual demand
Automatically reduces power when approaching atmospheric pressure, maximizing energy savings
Intuitive HMI touchscreen display
The operating interface is simple and easy to use.
Supports multiple display modes and communication options for connecting to a central monitoring system.
High performance input filter
The large inlet filter size helps reduce pressure loss.
Long filter lifespan, suitable even in dusty environments.
Integrated differential pressure switch, HMI alerts when filter cleaning or replacement is needed.
A full range of suction-side accessories is available, including cyclone filters, mist separators, and liquid filters
High quality soundproof cover
Superior noise reduction.
Optimized ventilation system for smooth and quiet operation
Compact design that saves installation space
