6. In the case of oil lubrication, check the filling level of the bearing box.
7. In the event of cooled sealing boxes, check the proper circulation of the cooling liquid
8. Check that all the guards for the moving parts have been properly fitted.
For the first start up, after making all the checks, this should be done with the drive valve closed, to
reduce the consumption of the pump as far as possible. When the running speed has been reached, the
valve should slowly be opened, observing at the same time the variation in consumption, until this opens
completely. In normal operation the consumption, measured in amperes, should not be over what is
stated on the motor plate.
9.2.- Stopping the pump
To stop the pump, the delivery valve should be returned to the original position as before the start up.
When installation has a anti-water hammer device there is no need to close the delivery valve for
stopping the pump.
Check that motor deceleration is normal and after it has completely stopped close the auxiliary circuits.
When the equipment is to be idle for long periods, the pump and piping should be completely drained, to
prevent the risks of frost during the winter and any possible rusting of the mechanical items that might be
caused through trapped liquid.
10.- HANDLING AND CONTROLS
Centrifugal pumps performance is simple and safe and does not require any exhaustive checking, though
to guarantee proper operation it is important to take the following points into account both the first time
this is started up and after a long period running:
1. Operation should be silent and vibration-free. After the first 200 hours' use, check proper
alignment of the pump-drive set as described in 8.3.- Alignment of the set.
2. Check that the flow and service pressure match what is determined in the work fields (see the
relevant technical documentation from Bombas Ideal S.A.).
3. For equipment with electrical motors, check that the input current (consumption in amperes) is not
over the values stated in the motor characteristics plate.
4. The heat produced by friction between the packing and the shaft (in the case of pumps supplied
with packing) is removed by cooling with the same liquid as is pumped through, for which purpose
a slight drip should be ensured. If the dripping is too high and cannot be reduced by tightening the
stuffing box, the packing will have to be replaced as described in the Maintenance section.
5. For externally cooled stuffing box should be checked that the cooling liquid is doing its job. Bear
in mind that the difference between input and output temperatures should range between
10/15ºC.
10.1.- Lubrication
The pumps with grease-lubricated bearings are supplied pre-greased from the factory. Nevertheless,
when these have been stored for long periods they should be slightly greased.
Below there is a table showing the regularity for greasing the different types of support.
