Dry-Running Rotary Vane Vacuum Pumps and Compressors SECO DC 0025/0040 BUSCH Seco rotary vane pumps/compressors were developed specifically for paper handling in printing presses and post-press processing equipment. They provide a reliable vacuum supply to hold, move or transport paper. Blast air is also generated to separate individual sheets of paper from a stack.
Seco rotary vane pumps/compressors guarantee vacuum levels exactly matched to the requirements of printing presses and post-press processing machines, and may be adjusted for throughput speed and paper quality. The blast air may also be set to allow optimal transition of sheets through the machines. An internal secondary inlet allows the vacuum and blast air supplies to operate independently. The blast air is cooled by an integrated heat exchanger.
The defining characteristics of Seco rotary vane pumps/compressors are completely oil-free vacuum and blast air generation, high availability and outstanding reliability. These characteristics are ensured by highly resilient and selflubricating special graphite rotor vanes, robust construction and lifetime-lubricated bearings. The compact dimensions of Seco units allow them to be easily connected or installed almost anywhere. The energy-efficient motors are economical in operation.
Maintenance may be carried out by the user – apart from visual inspection and the replacement of vanes and filter elements at the recommended intervals, no servicing is required. The latest generation of rotor vanes has an operating lifetime up to three times longer than vanes constructed of conventional materials.
Seco Pumps use the proven rotary vane operating principle. As the rotor vanes are self-lubricating, no operating fluids are required and compression is completely dry. Integrated filter elements installed as standard equipment protect the pumps from contaminants. Regulating valves for Vacuum Pumps and Compressors SECO DC 0025/0040 BUSCH and blast air are also fitted as standard, allowing the pump to be adjusted to the requirements of printing presses and post-press processing machines. A high-output ventilator ensures efficient heat removal from the motor and pump casing.
