APPLICATIONS These pumps are used extensively in industry and laboratories for production of medium and high vacuum. They are used as backing pumps in series with roots blowers, diffusion pumps etc. These pumps find applications in vacuum coating, molecular distillation, vacuum metallurgy, freeze drying, vacuum impregnation, air conditioning and refrigeration, vacuum lifting devices, packaging ma

APPLICATIONS • Pharmaceutical, Chemical & Industrial Machines. • Filling, Transferring, Holding. • Conveying, packing, Filtering.

FEATURES • Exhaust valve is designed to eliminate "rapping" noise. • Unique construction of the pump totally eliminates the sucking of air through the shaft seal. • Pumps can also be operated with SAE-30 motor oil instead of vacuum oil • Water Cooling Arrangement can be provided if required at extra cost.

OUTSTANDING FEATURES: • Silent and considerably vibration free running • Needs no silencer. • Mechanical shaft seals on either end of shaft • Maximum vacuum using water as sealant at 300 Centigrade and at sea level conditions : Single stage models will be 700 mm Hg. Double stage models will be 720 mm Hg. • Negligible maintenance and easy overhauling procedures. • Modification

Specially treated steel vanes ensures silent running and negligible wear on stator and rotor slots. Unique lubrication system positively feeds minimum quantity of oil to all important points. Oil from the exhaust is baffled, collected and returned back to oil chamber. Incoming air passes through fine filter in case in suction box before entering pump Regulation of vacuum and pressure can be done
