3 Installation
It is essential to observe the following instructions step by step to ensure 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 form running up inadvertently.
Observe all safety regulations.
3.1 Installation
The SOGEVAC
®
s can be set up on any flat, horizontal surface. Under the
four feet, there are metric threaded holes (M16x1.4) for securing the pump.
The oil level cannot be read properly if the pump is tilted and lubrication may
be affected.
The pump’s ambient temperature should be between 12°C (55°F) and 40°C
(104°F). By modifying the pump or changing the oil type, the pump can be
run at a other ambient temperature. Please consult us.
To ensure adequate cooling of the pump, leave enough space at the air
intake and exhaust points, and for access and maintenance (see Fig. 1-2-3
for SV630 B/SV750 B)
Make sure to keep the air intake of the motor clean.
3.2 Connection to system
The standard pump is not suitable for installation in exploision hazard areas
ATEX. Please contact us, when you are planning such an application.
Intake Side
■
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 pipings should take care of pumped
gases. It is the same for its tightness.
The pump is equipped with an inlet flange 100 ISO K/DN 100 PN 10
(SV630 B / SV750 B) or DIN 160 roots adapter (SV630 BF). Using suitable
connecting elements (see § 1.4) the pump can be connected to the vacuum
system.
The cross-section of the intake line should be at least the same as the one
for the intake port. If the intake line is too narrow, it reduces the pumping
speed.
If the process gas contains dust, it is absolutely essential to install a dust
filter in addition to the dirt trap supplied (see §1.4).
