• HELIX vacuum pumps are tri-lobe worm screw profile blowers specifically designed for vacuum plants that must convey gas free from polluting
substances, oil or water: this is made possible due to the lack of sliding parts, and therefore oil lubrication within the compression chambers.
• HELIX blowers do not need any auxiliary cooling system, as they are provided with a built in air injection cooling system.
• The specific and accurate lobes profiles grant high volumetric efficiency and high flow rates combined with minimized dimensions and vacuum
rates that can reach 93%.
• Operating without oil (no oil emission into the atmosphere) and without wear-proof operation, reduced maintenance.
• Silencers are designed to be installed in correspondence with the discharge and injection line (depending on the choice of model) of lobe
vacuum pumps (without lubrication). All silencers are equipped with coupling flanges.
STANDARD EQUIPMENT
• Volumetric pump with synchronised phase helical gears.
• Tri-lobe worm screw profile rotors, dynamically balanced rotors
to reduce vibrations.
• Splash lubricated bearings and gears in the front and rear boxes.
Internal combined seals: Y-seals and labyrinth seals with
PTFE/cast iron rings with discharge into the atmosphere. Seals
and gaskets for high temperatures.
• Side air injection cooling system with clapet valve. This valve
opens only in the vacuum functioning mode.
• Overheating thermostat on the exhaust port.
• Removable lifting points.
• Inductive sensor.
AVAILABLE ON REQUEST
• Hydraulic motor.
• Pulley for the belt drive.
• Injection muffler (compulsory accessory) and vacuum pump
exhaust.
• Air flow change-over valve (4-way valve).
• Flushing-Kit.
• HELIX 1200 only: Injection manifold with vertical port.
