Single Stage Liquid Ring Vacuum Pumps

Single Stage Liquid Ring Vacuum Pumps

AVA series pumps are designed and manufactured for use in the most critical applications, their main feature is that they are suitable for suction of contaminated gas mixtures, corrosive gases and vapors, explosive gases and vapors of any nature, up to the usual final vacuum, providing ultimate vacuum up to 180 mbar. They are manufactured to the highest quality standards.

Impeller design is located between the bearings and gas flows are collected from both ends of the pump through a common inlet and outlet manifold. The pumps are available with a free shaft end, so they can be connected to any electric motor through a flexible coupling. AVA pumps are often used as a compressor with discharge pressures of up to 2 bar. Thanks to their design, they are also available with ATEX certification. Design of the AVA pump range is very robust and simple to ensure the highest reliability.

Basic housing structure is made of cast iron with a bronze impeller. Other versions can be supplied on request, such as cast iron casing with SS316 stainless steel impeller or an all-stainless steel pump design. AVA pumps are used in all industrial vacuum applications due to their versatility and performance requirements. They are widely used in chemical, pharmaceutical, food, textile, woodworking and plastic industries for gas and steam extraction, vacuum infiltration, packaging, pneumatic conveying, soil recovery.
