2 Description of product
2.1 General description of the pump
Pumps of this type are multi-stage rotary pumps.
Series TH/STH use closed impellers in order to
minimizing power consumption and to optimize
hydraulic pump efficiencies. In addition, the
TH/STH series offers high pressures at short im-
mersion depths.
The pump shaft and the motor shaft are connected
by a coupling. The pump shaft is sealed by a rotat-
ing mechanical seal. The pump is protected again
impurity by a filter. Pump and motor form a compact
and space-saving unit.
Vertically mounted pumps are equipped with a
mounting flange. The pump end immerses into the
tank and the motor extends vertically above the
tank.
2.2 Intended use
The immersion pumps of the series TH/STH have
been especially developed to supply internally
cooled tools with coolant fluid within the limiting
application in accordance with table 1.
Limit of Application (Table 1)
ATTENTION
The pumps are to be operated within their design
limits. Applications outside of these limits are not
approved. The manufacturer is not responsible for
any damages resulting from use of the pumps in
such applications.
