1.1 Intended use
Richter pumps of the series MNK-S, MNK-SB and
SCK-S are plastic-lined centrifugal pumps for the con-
veyance of aggressive, toxic, pure and inflammable
liquids.
The Richter "self-priming" pump housing can be oper-
ated in conjunction with the drive or slide-in unit of
an MNK, MNK-B and SCK.
As the drive side is identical to that of normal-priming
pumps, components of such pumps are not described
in this manual; reference is made to the appropriate
operating manuals.
However, it should be noted that the mechanical seal
pump SCK of self-priming design must not be oper-
ated with a single mechanical seal as this does not
provide optimum sealing owing to the vacuum pro-
duced in the pump housing. In this case the well-
known quenched or liquid-sealed double mechanical
seals are to be used.
This operating manual only describes the special
features of the self-priming design of the MNK-S,
MNK-SB and SCK-S. In the event of overlaps, the
statements made in this operating manual take
priority over the operating manuals of the normal-
priming pumps.
The medium must not contain any solids as they
collect in the pump housing. If solids are, neverthe-
less, conveyed, the pump housing must be regularly
checked for the aggregation of solids and cleaned
from time to time.
The exact operating conditions, insofar as they are
specified by the customer, and the machine selected
for them are documented in the enclosed data sheet
including the performance features such as consump-
tion values, weights, materials and emissions.
If the pump is to be used for operating data other than
those intended, the customer must carefully examine
whether the design of the pump, accessories and ma-
terials are suitable for the new application.
in order to ensure the priming capability of the self-
priming pump for operating data other than the design
operating data, it is recommended to consult Richter.
The observance of the physical limits speci-
fied in the respective installation and operating
manual is important for perfect functioning and
safe operation, especially with regard to explosion
protection to prevent potential sources of ignition.
In connection with explosion protection, potential
sources of ignition (overheating, electrostatic and in-
duced charges, mechanical and electric sparks) may
result from inadmissible modes of operation; their
occurrence can only be prevented by adhering to the
intended use and observing the notes on safety rele-
vant to explosion protection in the installation and
operating manual.
