Tsurumi KTZ-series 22 kW Debut!!

Apr, 2021

-- New model of Tsurumi's flagship KTZ-series --

Since its foundation in Japan in 1924, Tsurumi Manufacturing Co., Ltd. has been engaged in the manufacture, supply and sales of various pumps including submersible pumps as key products, environmental devices and related equipment.

This time, two 22 kW models have been added to Tsurumi's flagship KTZ-series of submersible pumps which support a product lineup of models ranging from 1.5 to 15 kW.
The new models are available in two types: KTZ422 (4-inch) and KTZ622 (6-inch). These pumps provide a maximum head of 72.5 m and maximum capacity of 4 m3/min. Built with a cast iron body and high-chromium cast iron impeller, these pumps are advantageous in terms of durability and wear resistance. As the discharge design of these pumps, a top discharge side flow structure is used, which enables the slim body to be installed in a confined space and also ensures extended operation at a low water level.
Owing to these features, the KTZ-series qualify as heavy-duty, highly-reliable and continuous duty pumps that are suitable for harsh work environments such as mining, quarrying, construction and tunnel work sites.
Also, the Tsurumi's original multi-directional hose coupling structure enables flexible on-site setup for either vertical or inclined discharge with just a wrench.

Like all general submersible pumps from Tsurumi, these pumps are equipped with an anti-wicking cable, motor protector, dual inside mechanical seals with silicon carbide faces, and Oil Lifter as standard equipment.
Furthermore, as found on 7.5 kW and higher motor output models of the KTZ-series, the 22 kW models have seal pressure relief ports in the pump unit, which prevent pump pressure from being applied to mechanical seals.
In addition, the semi-open impeller mounted on the KTZ-series is stronger against wear compared to closed impeller, which reduces the performance degradation rate. This results in easier maintenance as frequent gap adjustment is not required. Also to compensate higher thrust load that acts on the bearings of a pump with closed impeller, Tsurumi adopts a double bearing and an impeller design that reduces the thrust load for KTZ 22 kW models.
These features are the results of original technologies and unmatched know-how that Tsurumi has cultivated over years of manufacturing pumps for construction purposes, so we firmly believe that you can assuredly use our pumps.

In addition to these pumps, Tsurumi offers a variety of pumps with excellent reliability and durability that can withstand harsh work conditions. To place an order, please contact us.
