18 SPECIAL VERSIONS
The KT pump is also available in the special version:
• KTR
The following information is helpful in deciding how to
choose and use this version.
Unless specified otherwise, observe the above instructions for
the standard KT pump.
18.1 KTR Pump
18.1.1 Operating instructions
The KTR 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.
