Atlas Copco’s Industrial Vacuum division is launching the DHS 065-200 VSD+ dry screw vacuum pump, offering lower lifecycle costs, higher productivity, less energy consumption and easy maintenance.

Built for rapid cycling and continuous operation applications, the DHS VSD+ is a clean, zero contamination dry vacuum pump that requires no water or oil cooling. Certified as oil-free in the category ‘Class Zero’ according to ISO standard 8573-1 the pump is free of oil emissions, including aerosol oil content in the outlet air stream. The reduced number of parts within the pump combined with the variable pitch screw design help increase efficiency and reduce maintenance.

Alexander Frerichs, Product Manager Dry Pumps, comments: “The new screw profile of the DHS 065-200 VSD+ offers best-in-class performance in its category. We set out to build a pump that would create a safer, cleaner and smarter industrial environment. The robust design, clean operations and remote monitoring and control capabilities makes it the perfect pump for industrial applications”.

Due to the completely dry operation of the DHS 065 - 200 VSD+, no oil migrates in the pump environment. It helps to create a cleaner and safer working environment. Alexander Frerichs says: “This is a great advantage especially in applications such as vacuum drying and cleaning, paper converting, sensitive and regulations-driven electronics manufacturing and food packaging industries, because there are no reactions with other process media or deposits inside the vacuum pump.”

Housed in a noise-reducing canopy ensures a noticeably quiet, vibration-free operation with a low-pitch sound level, the pump is equipped and controlled with the MK5 Elektonikon. This integrates the pump to plant management systems. Users get status updates on running and stopped hours, warning, and fault and shutdown indications. Combined with Atlas Copco’s SMARTLINK, the pump offers unrivalled remote monitoring capabilities.

Reduced maintenance is an integral feature of the DHS VSD+ series. The grease-lubricated bearings and the belt are the only parts which require replacement. The belt itself can be changed without external service support within 30 minutes. The robust canopy retains the integrity of the internal parts and can be removed easily. This reduces installation complexity and associated costs. Truly a clean, clever and compact vacuum pump.
