Operation
CAUTION !
Observe the basic safety instructions when using the WOB-L
®
Piston Pump,
chapter 2
.
5.3.1
Start-up
Make sure that when you start the pump, which may arise in the connection lines con-
densates, cannot penetrate into the pump.
►Action: additional suction side condensate separator
Always try to avoid aspiration of foreign body particles!
►Action: suction side inline filter
The WOB-L
®
Piston pump is switched on the power switch.
It is recommended to let the pump run for a few minutes before use. The warm-up im-
proves the eligibility of the pump.
5.3.2
Decommissioning
If vacuum applications with special steam load, the pump needs to run after the process
with an open vacuum port about 2 minutes and rinsed with atmospheric air.
This measure is used to cleaning the pump chamber and minimizes the corrosive attack
wetted material pump parts.
The WOB-L
®
Piston pump is switched off using the power switch.
5.4
Storage
The pumps are to be stored in a low-dust, interior room within the temperature range from
+ 5 to + 40 °C and at a relative air humidity < 90%.
Leave the protective elements on the suction and pressure ports. Another equally good pro-
tection may be used.
