Description:
The KTZ-series is Tsurumi’s flagship line of submersible pumps. Made with a cast iron body and high chromium cast 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 cover 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 original 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 to 22kW 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-series 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.
The KTD-series is a submersible heavy-duty slurry pump utilizing the KTZ-series as the base. It is designed to have more motor shaft power allowance than the KTZ to handle muddy water with higher specific gravities. An agitator suspends solids to assist in pumping sediments in combination with a dedicated strainer. This pump is suitable for transferring or draining bentonite slurry.
Available as optional specifications are an original “seawater-resistant pump” developed over many years by Tsurumi to enable seawater intake/drainage for long periods of time.
The cast iron body with high-chromium cast iron impeller enables it to withstand demanding conditions found in construction,aggregate and mining applications. The top discharge, side flow design assures efficient motor cooling even when it operates with its motor exposed to air.
Applications:
·Drainage sand water during construction and civil engineering operations.
·Deep well pre-drainage
Horizontal or vertical single-stage submersible pumps can be used as modular pump units. They can be equipped with various types of next-generation impellers, and can be installed in a wet or dry manner. They can be used statically or in combination with energy-saving motors in a mobile way. Explosion-proof models are also provided.
