Close Coupled Centrifugal Pumps
with threaded ports
Features

4.93.322
Compact Design
The compact design allows for easy installtion even in confined spaces.
Robust
The mechanical structure of the hydraulic parts in contact with the pumped liquid are
dimensioned to guarantee the maximum resistence to mechanical stress.
A unique design
The lantern bracket design prevents contact with the pumps rotating parts, providing
protection to the end user whilst allowing for inspection of the mechanical seal.
Reliable
The bearing and shaft are designed to ensure the reduction of the stress, providing
high reliability under all operating conditions.

Features
3.94.044
Flexible
The option to choose between cast iron and bronze materias for the hydraulic
parts in contact with the pumped liquid allows NMD series pumps to be selected
for use with different types of liquids.
Robust
The mechanical structure of the hydraulic parts in contact with the pumped liquid
are dimensioned to guarantee the maximum resistence to mechanical stress.
