New spencer S30104 standard overhung vacuum blower:
SPENCER OVERHUNG VACUUM BLOWER
VALVE: VALON model Q2116 Ball Valve
EXHAUST Filter unit (Rt Angle, see photos)
This pump was purchased in 2003 at the cost of over $35,000 and never installed. Unit is still sitting in a lab that was never set up. Came off a fluidized bed system (the project was canceled before lab was finished). Would be an excellent unit to aide in air movement into a "Bag House" or for exhausting dirty air that would be uncovered during mining operations etc..
Item is set up in Hubbardston Mass. Not connected to power. Sorry no testing but it was removed unused and 100% operational. This blower has a nice protective Jacket wrapped all around the units main body as you can see from photos.
Multistage Fabricated Centrifugal Blowers
Spencer multistage fabricated blowers cover an extensive line of styles and models used for a wide range of air/gas services in industrial, commercial, institutional and municipal applications. The three basic designs are standard overhung SOH (impellers mounted on extended motor shaft), four-bearing overhung 4BOH (impellers mounted on shaft coupled to motor shaft) and four-bearing outboard 4BOB (impellers mounted on shaft supported at both ends by self-aligning ball bearings, coupled to motor shaft). SOH and 4BOH machined are noted for the trademarked sugar scoop profile of their housings. These are among Spencer s oldest products, so the sugar scoop profile is your visual assurance of genuine Spencer quality that has endured for more than a century.
These blowers are manufactured of heavy gauge, cold-rolled sheet steel with a tensile strength of 50,000 psi, welded and reinforced, creating an extremely rugged construction. The inlet, outlet and housing are built as an integral structure for greater strength. The fabricated construction allows easy substitution of other metals to counter very high temperatures, chemical or corrosive conditions. We routinely use Hastelloy , monel, various stainless steels, aluminum, Cor-Ten steel and many others that provide specialized abilities.
The rotating impeller assembly within the blower housing has ample clearance, 1/8" or more, for simple, low-maintenance operation. The entire rotor assembly is dynamically balanced to ensure mechanical operation below 1.5 mils total amplitude on the bearing housing at design speed. With housing diameters from 14" to 88", these blowers can handle volume to 25,000 ICFM, pressure to 20 PSIG and vacuum to 15" Hg.
