STARTING
Before operating the pump, check that electrical and mechanical parts of the system have been correctly installed.
Make sure all safety devices are operative.
Make sure the pump’s direction of rotation is correct (section 11.1)
Check the seal and bearing oil level by means of the oil level sight glasses on the support (fig. 7a)
The seal is an oil-immersed model (Mobil Delvac SAE 15W-40.), and should be replaced after 5,000 hours of operation, or once a year.
12.1 Filling the pump casing
Fill the pump casing completely with the liquid to be pumped through the relevant hole on
the top of the casing (fig. 8).
With the pump stopped, the casing does not empty, meaning you do not need to fill it.
12.2 Priming
Warning: if the pump does not prime, do not operate it for more than 3 minutes to avoid overheating the liquid. If the pump does
not prime, refer to section 14.1
Engine-driven pumps should be brought up to running speed gradually.
Never
change the accelerator lever limit stop: at speeds higher
than those for which the engine is set, the pump absorbs more power than the engine can supply.
Never
exceed the maximum speed given on the pump nameplate.
When the pump has primed:
-
Make sure the current absorbed by the motor does not exceed the motor rated value, shown on the nameplate.
-
If the pump does not seem to be operating normally, it is imperative to stop the pump and determine the causes (see section 14).
Topping up oil
Top up oil using cap (1) for the seal and cap (2) for
bearings.
Pour in oil until it is half way up oil level sight glass (6)
for the seal and oil level sight glass (3) for bearings.
Draining oil
Drain oil using plug (5) for the seal and plug (4) for
bearings.
