CONSTRUCTION TYPE
SIHI liquid ring vacuum pumps are displacement pumps of uncomplicated and robust construction with the following particular features:
non-polluting due to nearly isothermal compressionoil-free, as no lubrication in the working chamberhandling of nearly all gases and vapoursable to handle water carry overeasy maintenance and reliable operationlow noise and nearly free from vibrationwide choice of material, therefore applicable nearly everywhereshaft not contact with the mediumprotection against cavitation as standardincorporated dirt drainincorporated central drainno metallic contact of the rotating parts
The SIHI liquid ring vacuum pumps LEME are single-stage ones.
APPLICATION
Handling and exhausting of dry and humid gases. The pumps are applied in all fields where a pressure of 100 to 900 mbar must be created by robust vacuum pumps.
The LEME is specially designed to handle additional water that is exhaust through the suction inlet.
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.
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.
