Installation and Operation
6.1 Installation
It is essential to observe the following instructions step by step to ensure a safe start-up.
Start-up may only be conducted by trained specialists. The pump can be set up on any flat,
horizontal surface. Under the four feet, there are metric threaded holes for securing the
pump. The oil level cannot be read properly if the pump is tilted. Pump risks running dry.
The ambient temperature should be between 12
°
C (55
°
F) and 40
°
C (104
°
F) depending
on oil type. To ensure adequate cooling of the pump, leave enough space at the air intake
and exhaust points, so as for access and maintenance. Make sure to keep the air intake of
motor clear.
6.2 Inlet side
The pump has an internally-threaded intake flange. Using suitable connecting elements
the pump can be connected to the vacuum system. The cross-section of the intake line
should be at least the same as the intake port. If the intake line is too narrow, it reduces the
pumping speed. We recommend applying either LOCTITE or TEFLON tape to the screwed
unions so that they are vacuum-tight (especially if gases are dangerous).
Pump should be connected to inlet line without any tension. Use flex lines or pipe
unions in your inlet and exhaust lines so that they can be easily removed for pump
maintenance.
The maximum pressure at the inlet may not exceed atmospheric pressure (about 1013
mbar). Never operate the pump in the presence of over pressures at its intake. Type of
materials used for mounting of canalizations should take care of pumped gases. It is the
same for its tightness.
If the process gas contains dust or particles, it is absolutely essential to install a dust
filter in addition to the dust trap. We recommend to install the dust filter horizontally or the
elbow. This ensures that when removing the filter, no particle falls into the intake port.
When pumping vapors, we recommend installing condensate traps or condensers on
the intake side
By pumping of dangerous gases, inlet line must be tight.
No particles or liquids may enter in the pump.
