The AZO vacuum pumps of the V...MM series offer high quality performance, durability and reliability. The two oppositely-rotating pistons have a shape that enables the sucker air to be compressed inside the pump. The vacuum head contains a pressure check valve that enables termination of air flow. The vacuum pump is driven by a motor, with a gear that offers precision and synchronization of two pistons. These pumps can be used for various systems and applications, due to multiple features and accessories that enable easy implementation. Their design is robust, highly wear-resistant, directly increasing the overall cost-effectiveness.
