3 If pumped fluid is contaminated with solid particles:
a. Install temperature sensor on case surface
b
Adjust temperature monitoring device according to the manufacturer’s specifications and to
the maximum allowable temperature of the housing surface by its temperature class.
4 For pumps with separate relief valves:
a Install a pressure relief valve in the pressure line and adjust it accordingly
b. Provide a return line into the tank
3.2 Operation
3.2.1
Stay within the maximum permissible surface temperature
Pumped liquid
Stay within the maximum permissible temperature on the order data sheet
Housing surface
(Only relevant to category 2)
If the pumped liquid is contaminated with solid particles, monitor the temperature of the case surface
so that maximum permissible temperature of the housing surface does not go higher than permissible
by the temperature class on the nameplate.
3.2.2
Avoid Overheating
(Only relevant to category 2)
Overheating results from the impermissible operating conditions of:
a. Dry Running
b. Operating pump while the pressure side valve is closed.
c. Operating pump while inlet side valve is closed
d. Operating outside the pumps design parameters
Monitor motor power to detect the above problems with overheating.
3.2.3
Do not operate in an explosive atmosphere.
(Only relevant to category 2)
If an explosive atmosphere occurs, switch off pump
