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.
The iron construction of KRS series extends the life of the pump. 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.
