High Pressure Industrial Blowers Model 7000 Heavy Duty Bi-directional Rotation 17 Series - Horizontal Air Flow 46 Series - Vertical Air Flow 57 Series - Horizontal Flow, Single Envelope Gas Service 81 Series - Vertical Flow, Single Envelope Gas Service 64 Series - Horizontal Flow, Double Envelope Gas Service 67 Series - Vertical Flow, Double Envelope Gas Service Model 7000 PD PLUS heavy duty industrial blowers are designed for high performance applications, up to 18 PSIG pressure boost or 17” Hg dry vacuum (24” Hg water injected). 17/46 Series This series has wide application in pneumatic conveying, wastewater treatment, and the general process industry where high pressure, high volume air is required. Seal areas are vented to atmosphere to relieve process pressure against the internal lip seals, and to provide oilfree air. 57/81 Series (Single Envelope Gas Service) This series is utilized in such applications as closed loop pneumatic conveying, fuel or process gas handling, or elevated pressure applications up to 100 PSIG discharge. Vent openings are tapped and plugged to prevent gas leakage. These fittings can also accept an inert gas purge for positive containment of the process gas. 64/67 Series (Double Envelope Gas Service) This series is built to laboratory standards where virtually complete sealing is required. In addition to the features shown on the 57/81 series, the drive shaft is mechanically sealed and the oil sumps are plugged to provide an even higher degree of leakage protection. Flexibility by Design Detachable mounting feet allow field conversion from horizontal to vertical flow, or vice versa without additional components. Maximum Efficiency Model 7000 PD PLUS models include extended tip rotor profile for increased displacement and operating efficiency versus any other blower in its class. Extra Capacity Oil Sumps Oversized end covers for the largest oil capacity of any blower in its class. End covers also include external ribbing for applications where cooling water is not available. Oil drain plugs are O-ring sealed for protection against leakage. Model Size Nominal Min. RPM @ Max. Disch. Press. Nominal Max. RPM @ Max. Disch. Press. Material Specifications: Housing: Cast iron End Plates: Cast iron End Covers: Cast iron Rotors: Ductile iron Shafts: Ductile iron cast integrally with rotor Bearings: Rotors - Double row ball Drive shaft - Cylindrical roller Drive Shaft: SAE 4140 forged alloy steel Gears: Heat treated alloy steel, helical cut Seals: 17/46 series - Lip and labyrinth type on rotor shafts; lip seal on the drive shaft 57/81 series - Mechanical and labyrinth type on rotor shafts; lip seal on the drive shaft 64/67 series - Same as 57/81 series plus mechanical sealing on the drive shaft Lubrication: Oil splash system, both ends For elevated pressure applications, 57/81 series and 64/67 series are available with high pressure sealing and testing to allow discharge pressures as high as 100 PSIG (18 PSI nominal maximum pressure boost) * * Blowers operating with a discharge pressure above 20 PSIG require mechanical rotor shaft sealing; above 25 PSIG requires hydrostatic testing and special high pressure seal leakage testing. Optional Cooling Coils: 7000 PD PLUS models can include cooling coils to provide cooling of lubricating oil with less than 1 GPM cooling water for high performance applications where external lubrication is not desired or practical. Optional Lubrication Systems: All 7000 PD PLUS models are available with integral pressure lubrication to provide positive bearing lubrication and filtration of lubricant for extreme applications. When optional lubrication systems are specified, the series numbers change as follows: Standard Splash Lube Optional Integral Pressure Lube All PD Plus blowers are factory tested to meet ISO 9001 registered quality Rotors are dynamically balanced to meet ISO1940 Grade 6.3 specifications.
