Dry Screw Vacuum Pumps

Product description

• Dry Vacuum Pumps by Economy Process Solutions have been designed with a more compact and efficient structure for industrial and process applications.
• They feature a patented continuously variable pitch screw design, which allows them to consume 30% less power than other dry vacuum pump designs on the market.
• The pumps generate a lower process gas discharge temperature, making them a highly effective and energy-efficient choice for a variety of applications.
• Dry Screw vacuum pumps are environmentally friendly pumps as there is no oil being used.
• These pumps can be operated via VFD, which helps to regulate the desired operating vacuum, and are also available with automation.
• The pumps are water cooled through the casing/jacket, which allows them to run in hot or cold conditions as required by the process application.
• The pumps have a simple, smooth rotor profile, which results in lower maintenance requirements.
• The gas/vapour transfer through the screw is straight, with a very short gas/vapour travel path length, which facilitates faster pump down time.
• The pumps have a one-piece, rugged jacketed body, without any partitions inside, for straight transfer of gas, liquids, and particles. This eliminates the problem of rotor jamming due to accumulation of slugs, liquids, and particles, which can occur in partition-type bodies.
• The pumps do not permit backflow of gas or slippages in gas transfer and compression.
• The pumps are Intrinsically Safe, with a leak-tight pumping mechanism and no sealing fluid for vacuum generation. This eliminates worker exposure to process gas and contaminated oil.
• The pumps do not have metal-to-metal contact between operating parts, and can handle wet acid vapours and high melting point media. Applications include chemical and pharmaceutical process plants, vapour recovery, vapour coating, extruders, distillation, and central vacuum systems.

Features

• Water cooled pumps, cooling through casing/jacket.
• Its designed to run hot or cold condition as required by the process application.
• Simple, Smooth Rotor Profile for lower maintenance Gas/vapour transfer through screw is straight, very short gas/vapour travel path length, which facilities the faster pump down time.
• One piece, rugged jacketed body, without any partitions inside, for straight transfer of gas, liquids& particle's. no problem of rotor jamming due to accumulation of slug, liquids & particles, in case of partition type body.
• Does not permit back flow of gas or slippages in gas transfer & compression.
• Intrinsically Safe : As the leak-tight pumping mechanism, and no sealing fluid for vacuum generation. There is no worker exposure to process gas and contaminated oil which is virtually eliminated.
• No metal to metal contact between operating parts. Handles wet acid vapours and high melting point media.
