The cast iron construction of Tsurumi’s KRS series extends pump life by preventing premature wear and failure from the abrasive materials found in mining, aggregate, and construction applications. Available in a variety of discharge sizes and horsepower, the KRS pumps are engineered to withstand even the most rigorous situations.
KRS series offers longer wear life on parts due to the slower impeller tip speed provided by 4-pole, 1800 RPM / 6-pole, 1200 RPM motors. Reducing impeller speed by half will extend your parts wear life by at least 2 to 3 times.
To prevent premature wear and failure from abrasive materials, Tsurumi’s dual inside mechanical seals are completely isolated in an oil chamber with an extra lip seal to protect mechanical seals from the abrasives.
KRS series exemplifies Tsurumi’s design for multi-purpose pumps to fit a wide variety of applications due to their simple construction, superb durability, and high efficiency.
