Detailed Description

Design & Structure Feature

- High efficiency, lower noise when driving with less afilure rate in wide range of usages.

- Vertical split casing allows easy maintenance.

- Flange is complied with KS, ANSI FF, RF type.

- Impeller is dynamically and hydraulically well balanced.

- (Option) Fan type impeller mounting is possible.

- Grease-lubricated ball bearing is used; Oil type is also available.

- Bearing housing is mounted in the flange and can be pinned to it for precise realignment.

- The short distance between bearings on the shaft gives low warpage.

- Stuffing box is a non-cooled type, Packing type is basic and mechanical seal type is optional.
