SIHI Liquid Ring Vacuum Pumps:
LEM Liquid Ring Pumps

Description
The LEM series, closed coupled, multi service, liquid ring vacuum pumps offer the ultimate in robust simplicity, and manufactured in North America. This series of pumps feature cavitation protection, single North American mechanical seal, single casing drain, continuous solids purge connection, ultimate vacuum approaching 29" Hg. (25 Torr), and minimum space requirements. LEM pumps are closed coupled to North American motors of NEMA design. Motors are supplied in compliance with ‘UL’ and ‘CSA’ requirements. These pumps require no base-plate for mounting, no coupling, coupling guard, or on-site alignment of pump and motor. Perfect for use in OEM equipment. LEM pumps are capable of handling many vapors, and gases using service liquids compatible with the metal parts and elastomers of the pumps and mechanical seal. Small quantities of liquid carryover and nonabrasive solids can also be handled. 		LEM Liquid Ring Pumps
