ELC Series Liquid Ring Vacuum Pump

Product description
Parameters

ELC Series Liquid Ring Vacuum Pump (In Close coupled design) are displacement pumps of uncomplicated and robust construction with the following particular features:
① nearly isothermal compression;

②oil-free, as no lubrication in the working chamber therefore non-polluting;

③Capable of handling of nearly all gases and vapours;

④ small quantities of entrained liquid can be handled;

⑤easy maintenance and reliable operation;

⑥low noise and nearly free from vibration;

⑦wide choice of materials, therefore applicable nearly everywhere;

⑧shaft not in contact with the medium;

⑨protection against cavitation as standard;

⑩incorporated dirt drain,no metallic contact of the rotating parts。
