Vertical Centrifugal Pumps Bearing-Free Sealless Stainless Steel from Sethco

Bearing Free, Sealless 316 Stainless Steel Vertical Centrifugal Pumps
Designed for Corrosive Liquid Applications

Vertical Centrifugal Pumps, Bearing-Free, Sealless, Stainless Steel, SethcoThe “ZSX series” stainless steel vertical centrifugal pumps are completely corrosion resistant and are recommended for transferring, recirculating and agitating a wide range of chemical, laboratory and industrial process applications.
Like our popular “ZDX” series, these stainless steel models incorporate a unique opposing twin-impeller design. The design feature provides high volume circulation and eliminates leakage up the pump column. No bearings or seals permit dry running without damage.

The pumps are engineered to provide flows up to 100 GPM (378 LPM) and pressures up to 68 TDH (20 M). All wetted parts are precision manufactured from 316 stainless steel.

Features

  • Bearing free, sealless design permits the pump to run dry without damage.
  • Mounts inside or outside of tank.
  • Corrosion resistant 316 stainless steel construction.
  • Transfers corrosive liquids to 100 GPM (378 LPM).
  • Pressure to 58 feet TDH (20M).
