Bơm chân không Liquid ring vacuum pumps LEM 90, LEM 125, LEM 150, LEL 90, LEL 125, LEL 150


Bơm chân không (Liquid Ring Vacuum Pumps) Sihi LEMA / LELA là dạng bơm chân không 1 cánh dùng vòng nước để làm kín, có cấu tạo không phức tạp và kết cấu vững chắc. 

LEMA / LELA có áp suất làm việc từ 33 đến 1013 mbar, thể tích hút 32 đến 170 m3/h

LEMA / LELA là dòng bơm nhỏ gọn có 6 kích cỡ LEM 90, LEM 125, LEM 150, LEL 90, LEL 125 và LEL 150

CONSTRUCTION
Flowserve 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 Flowserve 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 (see catalogue part accessories).
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.
