Exhaust connection (Pressure side)
The exhaust connection (pressure port) also consists of a hose nozzle DN 8.
a)
Exhaust line for vacuum applications:
Thick-walled rubber vacuum hose 8 x 5 mm hose nozzle DN 8.
PVC fabric hose and hose clamp 8 x 3 mm clamping range 8 - 16 mm.
b)
Exhaust line (compressed-air line) with compressor application:
PVC fabric hose and hose clamp 8 x 3 mm clamping range 8 - 16 mm.

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
