Tsurumi has expanded its KTZ series with two 22 kW models, the KTZ422 (4 inch) and KTZ622 (6 inch) submersible pumps, supporting models with power from 1.5 to 15 kW.
The KTZ series is designed for harsh environments such as mining, quarry, construction and tunnels. The new models offer a maximum head of 71 m and a maximum capacity of 4 m3 / min. The cast iron body and high chrome cast iron impeller make them durable and wear-resistant. An upper upstream flow structure allows the compact body to be installed in confined spaces and ensures longer operation at low water levels.
The pumps come standard with a wick protection cable, a motor protector, two inner mechanical seals with silicon carbide faces and an oil lifter. The 22kW models also feature seal pressure relief ports in the pump unit that prevent pump pressure from being applied to mechanical seals.
The semi-open impeller mounted on the KTZ series is more wear-resistant than a closed impeller, and the double bearing and impeller design reduces the pressure load for KTZ 22 kW models.
