Clogging-Proof Hydraulics

The AVANT™ hydraulic components have been designed to maximize efficiency, eliminate clogging, and provide for large free passage of solids.

All models with open channel impeller feature an axial adjustment system allowing the impeller clearance to be restored. This feature maintains performance even as components wear over time.

One of the biggest problems, today, in wastewater, is clogging of impellers due to fibrous and stringy materials.

The solution to this type of clogging is the AVANT™ open channel impeller pump, adopting this new and innovative Anti-Clogging System (ACS). The ACS uses the centrifugal force of the impeller to pull out the stringy material via a spiral groove cut into the diffuser plate. This combination eliminates the fibrous material clogging of the impeller.

Anti-Clogging System

More Reliability with Molib-Tech

The Molib-Tech coating, adopted by Tsurumi, is specially formulated to prevent and reduce wear due to erosion or cavitation on pump impellers, suction flanges, and housings.

The Molib-Tech coating used by Tsurumi was specifically developed to:

  • Increase component wear resistance
  • Improve durability
  • Keep performance consistent over time, even in extreme duty conditions
