Product Description

Review the intended use, key features, and technical information supplied for this product.

Product Overview

The Tsurumi KTZ422 is a 4-inch (100mm discharge bore) heavy-duty submersible drainage pump from the KTZ flagship series, fitted with a 22kW, 2-pole, 3-phase motor and a high-chrome cast iron semi-open impeller engineered to resist abrasion from sediment and solid particles. The pump body is built from durable cast iron and paired with a dual silicon-carbide-faced mechanical seal and Tsurumi's exclusive oil lifter lubrication system, allowing it to keep running reliably even after long periods at low water levels in abrasive, sediment-heavy site conditions. The KTZ422 is suited to construction sites, tunnelling works, mines and quarries that require high-volume, high-head heavy-duty dewatering.

Key Features

High-chrome cast iron semi-open impeller for outstanding wear resistance and extended service life under heavy-duty dewatering
Dual silicon-carbide-faced mechanical seals offering roughly 5x the corrosion, wear and heat resistance of tungsten carbide
Original oil-lifter design keeps seal faces lubricated and cooled even when oil drops to one-third of its normal level
Seal pressure relief port protects the mechanical seal and discharges abrasive wear particles
Anti-wicking cable core prevents capillary water ingress and condensation inside the motor housing
Multi-directional hose connection lets operators switch between vertical and inclined discharge with just a wrench

Applications

Construction dewatering
Pumping accumulated water from large excavations and building sites

Tunnelling works
Continuous groundwater ingress removal in tunnels and underground works

Mining / quarrying
Heavy-duty dewatering of sediment-laden water at mines and quarries

Municipal / emergency drainage
Flood response and temporary drainage on large-scale projects
