3 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 standard pump is not suitable for installation in explosion hazard areas
ATEX. Please contact us, if you are planning such an application. Before
installing the pump you must reliably disconnect it from the electrical power
supply and prevent the pump fr
o m running up inadvertently.
Observe all safety regulations.
3.1 Setting up
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 risk to run
dry and oil level switch may not react correctly.
The Sogevac
®
pump can pump gases and vapo u rs, provided that the gas
ballast valve is installed and open and the pump has reached its operating
temperature.
Pump in o peration is hot and some surfaces could reach a temperature higher
than 80°C (176°F). There is a risk of burn by touching. Take note of warning
labels on the pump.
Observe the safety regulations.
Inlet connection
See safety instructions page 3.
The pump has an internally-threaded intake flange. Using suitable connecting
elements (see § 1.3), 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 when 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 canalisations should take care of
pumped gases. It is the same for its tightness.
■
The inlet pipe should be installed with a rising slope towards the pump to
avoid condensates flowing into the pump.
If the process gas contains dust, it is absolutely essential to install a dust
filter in addition to the dust trap supplied (see § 1.3).
