Chemical Process Pump =
Series - STHZ
Discharge (mm) - 100
Impeller dia (mm) - 315

General Description

Model STHZ Centrifugal Pumps are of horizontal, single-stage, Singlesuction, volute casing design that corresponds with regard to sizes, capacities and main dimensions to DIN 24256 and ISO 2858 up to size 400. In addition a number of other sizes are available. The rear pull-out design enables the bearing pedestal including impeller and shaft seal to be removed with the Volute casing left in position. The removal of the driver can be avoided if a spacer coupling is used. The limits of the application depend on pump size and materials used. The direction of rotation of the pumps is always clockwise When viewed from drive-end.
