Introduction of Vogelsang’s ASU
Vogelsang has introduced its new Automatic Supply Unit (ASU), a supply system designed to cut pump operating costs. The new ASU has been specially developed by Vogelsang’s engineering team in Germany to keep mechanical seals in rotary lobe pumps running for longer and increase the service life by 1.5 times, reducing the frequency of changing the seals by as much as 33%.
Innovative Design for Extended Pump Life
While conventional supply systems are essential to keep the lubricant in a mechanical seal at a constant level and maintain the pressure in its buffer chamber, they can consist of many parts that require additional installation space. Vogelsang’s new ASU is much smaller than previous designs, requiring much less installation space.
Jonathan Gutteridge, Managing Director of Vogelsang, said, “Pumps obviously play a vital role in so many industries, and plant operators will know how frustrating downtime is when pumps need repairs or maintenance work. Our team has created this new unit to significantly lower pump operating costs by extending the life of the mechanical seals, reducing the amount of new seals needed, and, subsequently, less stoppage for maintenance work. Its small dimensions mean our rotary lobe pumps can be installed in the smallest spaces. As with every piece of Vogelsang equipment, it has been designed to be easy to service and maintain.”
The patented system, similar to a drinks can, consists of a reciprocating piston pump that pumps the buffer medium into the chamber with every revolution. In this way, the chamber pressure is kept constant at either 2.0 or 4.3 bar.
