CONSTRUCTION:
SIHI liquid ring vacuum pumps are displacement pumps of
uncomplicated and robust construction with the following particular
features:
Non-polluting due to nearly isothermal compression
oil-free, as no lubrication in the working chamber
handling of nearly all gases and vapours
small quantities of entrained liquid can be handled
easy maintenance and reliable operation
low noise and nearly free from vibration
wide choice of material, therefore applicable nearly
everywhere
shaft not contact with the medium
protection against cavitation as standard
incorporated dirt drain
incorporated central drain
no metallic contact of the rotating parts
The SIHI liquid ring vacuum pumps LEM/LEL are single-stage
ones.
APPLICATION:
Handling and exhausting of dry and humid gases; entrained liquid
can be handled during normal duty. The pumps are applied in all
fields where a pressure of 33 to 900 mbar must be created by
robust vacuum pumps.
NOTE:
During operation the pump must continuously be supplied with
service liquid, normally water, in order to eliminate the heat
resulting from the gas compression and to replenish the liquid ring,
because part of the liquid is leaving the pump together with the
gas. This liquid can be separated from the gas in a liquid separator.
It is possible to reuse the service liquid. The pumps are equipped
with a device by which the contaminated service liquid can
continuously be drained during operation (dirt drain), if necessary.
The direction of rotation is clockwise, when looking from the drive
on the pump.
