IDENTIFICATION CODES
Each pump is supplied with the serial and model abbreviation and the serial number on the rating plate,
which is riveted onto the support side. Check these data upon receiving the goods. Any discrepancy
between the order and the delivery must be communicated immediately.
In order to be able to trace data and information, the abbreviation, model and serial number of the
pump must be quoted in all correspondence.

GENERAL NOTES
"TRM" pumps are designed and built for the transfer of liquid chemical products having a specific weight,
viscosity, temperature and stability of state appropriate for use with centrifugal pumps in a fixed installation,
from a tank at a lower level to a tank or a pipe to a higher level. The characteristics of the liquid (pressure,
temperature, chemical reactivity, specific weight, viscosity, vapour tension) and the ambient atmosphere
must be compatible with the characteristics of the pump and are defined upon ordering.
The pump's performance (capacity, head, rpm) is defined upon ordering and specified on the identification
plate.
"TMR" and pumps are centrifugal, horizontal, single stage, coupled to a non-synchronous electric motor via a
magnetic coupling, with axial inlet and radial outlet for connection to the hydraulic system. They are foot-
mounted for floor fixing.
"TMR" pumps are not self priming.

The liquid to be pumped must be clean for the R
dimension and solid part hardness must be agreed during the offer).
Clockwise rotation seen from the motor side.
Make sure that the chemical and physical characteristics of the liquid have been carefully evaluated for pump
suitability.
Verify the compatibility with the phisical-chemical characteristics of the liquid.
The specific weight that can be pumped at 25 °C (liquid and environment) referred to max flow (50 e 60 Hz)
depend upon the type of construction:
normal contruction N (stamped on the rating plate)
heavy duty construction P (stamped on the rating plate)
The specific weight that can be pumped at 70°C is 10% less than that at 25°C.
The level of cinematic viscosity must not exceed 30 cSt so as not to significantly modify the pump's
performance. Higher values up to a maximum of 100 cSt are possible provided that the pump is equipped
with suitable impeller to be defined upon ordering.
