KTZE Series Dewatering Pump (Auto Type)

The KTZ series is Tsurumi’s flagship line of submersible pumps. Made with a cast iron body and high chromium iron impeller, the pumps can withstand the most demanding conditions found in construction, aggregate and mining applications. 

Versatility is increased as each model has the capability of being easily converted between high head and high volume performance with a simple change of impeller, suction plate and hose coupling. Dual silicon carbide mechanical seals are isolated in the oil chamber to protect the seal faces against abrasion and corrosion.

In addition, the seals are enclosed in Tsurumi’s patented Oil Lifter to ensure reliable lubrication and cooling. This design exceeds the standard configuration of competitors and offers a longer mechanical seal life for a more reliable pump. 

Pumps with a 7.5 or 11 kW motor incorporate seal pressure relief ports, therefore mechanical seals are exposed only to the pressure developed by the sump submergence level. This virtually eliminates the premature wear and failure of mechanical seals in higher pressure applications. 

The KTZE is an automatic pump without cumbersome floats. An innovative electrode type relay unit built into the pump automatically starts and stops the pump to eliminate dry-running. This mechanism greatly reduces power consumption and extends operating life!
