18.2 KSGR pump
18.2.1 Operating instructions
The KSGR series pump has been designed to
operate in environments with atmospheres that are
not potentially explosive and for using water rich
in particulate, therefore it is considered ideal for
systems with fluid recirculation.
The durability of the piston seals is directly in
relation to the percentage of the presence of solids
in the fluid as regards both their size and their
density.
For a long seal life we recommend a particulate
grain size of no more than 200 micron and 20% max.
in volume.
For more information and a general system layout,
see par. 9.7.

The maximum permissible water temperature is
40°C. However, the pump can be used with water up
to a temperature of 60°C, but only for short periods.
In this case, it is best to consult the Technical Office
or Customer Service Department.
18.2.3
The rated specifications stated in our catalog are the
maximum that can be obtained by the pump. Independently
of the power used, the maximum pressure and rpm indicated
on the specification label can never be exceeded unless
prior formal authorization is given by our Technical Office or
Customer Service Department.
18.2.4
The minimum permissible speed of the crankshaft for these
types of pumps is 100 rpm; any rpm other than as shown in
the performance table (see par. 18.2.5) must be expressly
and formally authorized by the Technical Office or Customer
Service Department.
