Vertical Flow Dry Screw Vacuum Pump

Description

Tuthill Vacuum & Blower Systems (TVBS) is now offering a vertical flow dry screw vacuum pump. Built in Springfield, Missouri, the KDS425 is now available for industrial or process applications.

The latest innovation in 100 years of KINNEY® brand vacuum pumps, the KDS425 offers a long list of features that provide excellent benefit to OEMs as well as end-users:

  •  Vertical cantilever design keeps process condensable from collecting in the pump process chamber
  • Process seal design with gas purge eliminates process chemical migration to atmosphere
  • High nickel content rotor construction is inherently corrosion resistant
  •  The absence of external seals ends leaky driveshaft mess
  • Variable pitch offers better efficiency compared to straight pitch designs
  • Dry running operation stops pump oil contamination
  • Thermostatic temperature control automatically adjusts for wide variations in heat load
  • Relatively high internal pump temperatures keep vapor loads from condensing in the pump
  • Standard NEMA or IEC frame motors are easily adapted for practically any application
  • Process components are easy to service and clean without disturbing the utility connections
  •  Optional Xylan/Nitrocoat coatings ensure pump longevity in corrosive environments
  • Rotors can be replaced without the need of replacing or moving the entire machine
  • The cogged belt drive provides quiet, no slip or stretch operation
  • The only dry screw vacuum pump made in America ensures prompt service and parts availability

“Based on the findings of an extensive Voice of the Customer process, we learned exactly what the market and segments within the markets really wanted in a dry vacuum pump,” said Dave Reader, lean product development manager at Tuthill. “Customers told us loud and clear there were definite advantages they liked about dry vacuum pumps versus wet vacuum, especially the benefits as to operations and environmental impacts. But there were drawbacks inherent to various dry pump configurations. The new KDS series is the result of combining customer feedback and 100 years of vacuum manufacturing and application experience,” Reader said.

The KDS425 offers industry leading performance near atmosphere, resulting in faster pump-down times and reduced batch times. The top down vertical flow design results in gravity aiding continued movement of particulates and condensate to the exhaust of the pump, isolating it from the rotor chamber. And, the KDS425 was designed for in-place service. In the event of process upset, the rotors are accessible with common hand tools and the machine does not have to be moved. No parts are necessary for cleaning the rotor chamber and when interval maintenance is needed, all can be performed without factory assistance.
