e-SH SERIES
GENERAL INTRODUCTION
The new and improved Lowara e-SH Series is a high performance stainless steel centrifugal end-suction electro-
pump with single stage, axial flanged suction port, radial flanged discharge, and horizontal shaft.
The e-SH is fully made in AISI 316 stainless steel which makes it suitable for handling water as well as non-
aggressive or moderately aggressive fluids.
The pumps are equipped with intercheangeable mechanical seals, IE3 efficiency motors, and have a back pull-out
design (impeller, bracket and motor can be extracted without disconnecting the pump body from the piping).
The e-SH series pumps are available in the following constructions:
