Busch has significantly extended its series of dry-running Mink claw vacuum pumps. To achieve this, vacuum modules were designed that achieve suction capacity of up to 900 cubic metres per hour and more through the combination of several Mink claw vacuum pumps. These Mink MP vacuum modules were designed for operations which require high suction volumes, dry compression and high availability. Thanks to their modular construction, Mink vacuum systems can be excellently adapted to changing process conditions by altering the number or size of the Mink claw vacuum pumps in operation. Mink claw vacuum modules work extremely economically thanks to their non-contact compression principle. Because the moving parts in the compression chamber do not come into contact with one another, the vacuum pump operates 100% wear-free. Operating fluids such as oil or water for cooling or lubrication are not needed in the compression chamber. For the operator, this means almost no maintenance and no replacement of wear parts, resulting in no costs for downtime, maintenance work or replacement parts. The costs for operating fluids are significantly reduced, as a gearbox oil change is only required every 20,000 operating hours, which - even in three-shift continuous operation - is only reached after more than two years. Thanks to the non-contact and dry compression principle, a high level of efficiency can be achieved using significantly less energy than comparable suction volumes achieved by other mechanical vacuum pumps. It is possible to operate the pump using frequency-controlled motors, which further reduces energy costs. Mink claw vacuum pumps are IE2 motors. The extension of the Mink series now facilitates suction volumes of 60 to 900 cubic metres per hour (50 Hz) or up to 1,080 cubic metres per hour (60 Hz) as standard. Even higher suction volumes can be achieved on request through the parallel connection of further vacuum modules.
