Oil-Sealed rotary screw pumps with variable speed drive (VSD) technology
Clean. Silent. Energy-efficient. Our GHS VSD+ cuts your energy costs by an average of 50% and increases production speed. The GHS VSD+ is a range of highly efficient, intelligent vacuum pumps with Variable Speed Drive (VSD).
Based on the well-known and durable plug-and-play design principles of our compressors, these vacuum pumps have been designed to perform optimally at operating pressures commonly found in industrial applications.
Efficient and reliable
The engine of any central vacuum system is the vacuum pump. Variable demand from your process often leads to frequent start-stops. These can in turn lead to mechanical and electrical motor problems such as overheating, fan breakage, oil degradation and vane delamination.
Traditionally, the way to overcome these problems is to use a wide pressure band to limit the number of stop-starts. Unfortunately this is not a cost-effective solution. A much better solution is to use a Variable Speed Drive (VSD). The vacuum pump with a VSD only delivers what is required.
The GHS VSD+ series vacuum pumps are ideal for a range of applications in plastics, glass, bottling, canning, wood, packaging, printing and paper, meat packaging and many more. The GHS 350-900 VSD+ is the ideal solution when a dedicated pump is required in the production area. The GHS 1300-5400 VSD+ can also be set up as a dedicated solution but is normally used in the utility room of
central vacuum system applications.
GHS VSD+ is available in Turbo version for fast cycling and dedicated configuration and as well in Humid version with a greater water handling capability. An energy recovery option can also be added on GHS 1300-5400VSD+, allowing you to recover up to 75% of the power input.
The GHS VSD+ series have shown a significantly better performance against traditional fixed speed technologies; in average, 50% energy savings.
