When you’re operating a hydraulic submersible dredge pump equipped with side cutters, you aren’t just moving water—you are managing a high-velocity stream of abrasive rock, gravel, and silt. At TUSSU® PUMP, we know that in these demanding environments, the “grind” is literal.
Your pump’s internal components are under constant attack. That is why our Back Wear Liners are engineered not just as parts, but as a critical, sacrificial defense system designed to keep your operations running without unplanned downtime.
The First Line of Defense: TUSSU® Back Wear Liners
Positioned strategically on the non-suction side of the impeller and casing, the back wear liner acts as the indispensable armor for your slurry dredge pump. For hydraulic cutter pumps facing the toughest muck and sediment, these liners absorb the punishing impact and scour that would otherwise destroy your core pump housing.
Why TUSSU® Liners are the Industry Standard:
- High-Chrome Toughness: Cast from ultra-durable High Chrome (Cr27) alloy, these liners are heat-treated to withstand the most aggressive abrasive slurries.
-
Specialized Rubber Options: For applications involving fine, high-velocity sand or acidic environments, we offer Rubber Wear Liners that provide superior “bounce-back” resistance against erosion.
-
Extended Service Life: By shielding the volute and the mechanical seal area, our liners prevent the rapid degradation of your most expensive submersible dredge pump components.
Optimized for Pumps with Side Cutters
Running a hydraulic dredge pump with side cutters adds a layer of complexity. The cutters stir up compacted solids, creating a high-density slurry that enters the pump at extreme pressure.
Without a high-performance TUSSU® back wear liner, this turbulence causes “recirculation wear” behind the impeller. Our liners are designed to control this flow, protecting the pump investment and ensuring that your hydraulic submersible dredge pump maintains its flow rate even as the project gets tougher.
Total Support for Your Dredge Pump Fleet
TUSSU® PUMP doesn’t just sell parts; we provide dredge pump protection strategies. Whether you are working in mining, tailing ponds, or coastal dredging, we supply the full range of accessories to keep your fleet in the water:
-
Hydraulic Side Cutters: High-torque agitation for compacted material.
-
High-Efficiency Impellers: Perfectly balanced for our back and front liners.
-
Agitators & Cutting Heads: Designed for maximum solids concentration.
-
Replacement Kits: Everything you need for a field-overhaul of your submersible dredge pumps.
Stop the Damage Before It Starts
In the dredging world, the cost of a part is nothing compared to the cost of a pulled pump and a stalled crew. TUSSU® heavy-duty liners deliver the reliability you need to finish the job on time.
If your hydraulic cutter pumps are eating through standard parts, it’s time to upgrade to a sacrificial defense system that actually lasts.
