Tsurumi KTZ Heavy Duty Submersible Drainage Pump

The Tsurumi KTZ Series Submersible Drainage Pump is an industry-standard workhorse designed to withstand high head demands and abrasive liquids across heavy construction sites, aggregate quarries, and civil engineering projects.

Constructed with a cast iron pump body and a 420 stainless steel shaft, the KTZ range offers exceptional resistance against mechanical stress and wear. Its versatile top-discharge design enables continuous cooling even when operating at low water levels, while the discharge connection can be reconfigured vertically or at an angle to prevent hose kinking.

Key Features & Benefits

• Heavy-Duty Construction: Cast iron casing combined with high-chromium iron impellers provides extreme resistance against abrasive sand, gravel, and slurry.
• 420 Stainless Steel Shaft: Built with a high-tensile 420 stainless steel shaft to withstand intense torsional load and prevent fatigue failure.
• Heavy-Duty Cable Options: Supplied standard with 20 metres of H07RN-F rubber power cable. Individually Screened Cable (IDS) is available on request for mining and quarrying safety compliance.
• Field-Changeable Discharge Outlet: Discharge port can be oriented vertically or angled to suit tight sumps and keep layflat hoses free of kinks.
• Top-Discharge Flow-Through Cooling: Pumped liquid flows directly around the motor frame, allowing continuous operation at low water levels without motor overheating.
• Patented Oil Lifter: Ensures double mechanical seal faces remain continuously lubricated, extending operational lifespan under tough site conditions.
• Anti-Wicking Cable Entry: Prevents water from creeping into the motor housing if the power cable becomes cut or damaged on site.

Applications

• Heavy site dewatering for deep foundations, retention ponds, and civil trenches
• Quarrying, aggregate washing, and gravel pit drainage (IDS cable option available)
• Tunnel excavation, mining shafts, and underground infrastructure projects
• High-head dewatering and emergency flood relief pumping

Note: The Tsurumi KTZ series operates on 400V three-phase power. All standard models include 20m H07RN-F cable. If your site requires IDS (individually screened) cable or high-head configuration advice, please contact our technical sales team before ordering.
