Maximum oil temperature
for air cooling water cooling
Normal operation up to 80 °C 40 °C ± 3 °C, with the thermostatic valve
set in the factory
Warning range over 80 °C over 60 °C
Fault for ATEX operation
Fault for none-
ATEX operation over 90 °C over 70 °C
In the case of ATEX operation the normal operation operating conditions
must not be exceeded. The SP-Guard must be wired and integrated within
the system controller so that the pump is shut down as soon as the warning
range is reached.
If the temperature of the oil deviates during normal loads and ambient con-
ditions from the process dependent standard values, the oil cooler should
be checked to see if it has accumulated any dirt.
3.6 Connecting the Cooling Water
(for water cooled pumps only)
Operation without cooling water will damage the pump.
Operate the pump only with the fan cover in place. The SP 630 F can suf-
fer severe damage in the case of restricted cooling.
In the case of several pumps, each pump must be connected separately
to the cooling water. A “series connection” of several pumps is not permis-
sible as otherwise due to the control action of the thermostatic valves this
may cause an interruption to the cooling water flow.
The pump is supplied without cooling water in the heat exchanger.
Unlock the quick locks at the fan covers (see fig. 4.2 or 4.3) and open the fan
cover
The thermostatic valve (fig. 5.2) is set to 40 °C oil temperature as factory
default.
Do not confuse water supply and return.
For the cooling water connections use only flexible hoses of sufficient pres-
sure and temperature resistance.
Connect cooling water supply line and cooling water return.
Only at an oil temperature of approximately 40° C will the thermostat open
and the cooling water flow. At 20° C this takes approximately 10 minutes.
Cooling water throughput may vary between 0 and 12 litres per minute
depending on the temperature of the cooling water.
