Pump Types
Oil Filled Rotary VaneVane :These pumps use oil to seal around the vanes to achieve vacuum to 0.5 Torr or 29.9 "Hg. Single pump capacities range from 1 to 460 cfm or 630 cubic meters per hour. Most common pumps for vacuum to 29.9 "Hg.
Laboratory Pumps: We have a two-stage oil rotary pump for vacuum to 15 microns or 0.015 torr. These pumps are quiet and efficient with flows of 1.5, 3, and 5 cfm. Complete with exhaust filter, switch, overload protection, and various inlet options.
Oil Free Rotary Vane: These pumps contain no oil in the pumping chamber and can achieve a maximum vacuum of 27.5 "Hg. They use a special composite vane to ensure close contact with the cylinder wall. Low maintenance with good vacuum.
Oil Free Piston: These pumps are smaller in capacity and use a special teflon PFTE ring with a reciprocating piston to generate a maximum vacuum of 29.13 "Hg depending on the model. These pumps have a flow of 2 to 8 cfm. Their compact size and weight make them ideal for many applications.
Liquid Ring Self-Contained: This patented liquid ring technology is used in many food applications where there is the possibility of water carry over into the pump. Vacuum to 28"Hg can be obtained. Able to tolerate highly moist air and water carry over.
Regenerative Blowers: These oil free blowers are very good for large flow and vacuum to about 200 inches H2O or about 14"Hg. Flow decrecaes as the pressure increases. High flow for maximum air velocity to suspend solids.
