    1. INTRODUCTION CONGRATULATIONS on your purchase of a new Mechanical Vacuum Booster from Tuthill Springfield. Please examine the booster for shipping damage, and if any damage is found, report it immediately to the carrier. If the booster is to be installed at a later date make sure it is stored in a clean, dry location and rotated regularly.

    Refer to diagrams in this manual for proper rotation and orientation in inlet and discharge. Tuthill Springfield model 9000 mechanical vacuum boosters are positive displacement type units, whose pumping capacity is determined by size, operating speed, and differential pressure conditions. Vacuum boosters employ rotors rotating in opposite directions within a housing closed at the ends by end plates.

  • Page 7: Installation

    NOTE Specially ordered blowers with nonstandard construction, or with rotor end clearances greater than shown within the Assembly Clearances table, will not have the operating limits specified here. Contact your Tuthill Springfield sales representative for specific information. NOTE Special attention must be paid when a vacuum booster has a higher than standard ambient suction temperature.
  • Page 8 WARNING The bare shaft booster can generate excessive noise. Methods to reduce the noise levels by installing inlet and outlet silencers will be required. Even with inlet and outlet silencers, hearing protection will be required. WARNING Customers are warned to provide adequate protection, warning and safety equipment necessary to protect personnel against hazards in the installation and operation of this equipment in the system or facility.

  • Page 9: Location

    A booster may be driven by direct-coupling to the driver or by V-belt drive, to obtain other speeds within approved range. (See the Motor Drives section for more information.) Boosters from Tuthill Springfield are internally and externally treated after factory assembly and testing to protect against rusting in normal atmospheric conditions prior to installation. The maximum period of internal protection is considered to be up to 6 months under average conditions, provided closing plugs and seals are not removed.

  • Page 10: Soft Foot

    Repeat steps 4 and 5 on remaining feet. 5.2 SAFETY Tuthill Springfield recommends the use of relief valves to protect against excessive pressure or vacuum conditions. These valves should be tested at initial start-up to be sure they are properly adjusted to relieve at or below the maximum pressure differential rating of the booster.

  • Page 11: Lubrication

    5.3 LUBRICATION Every booster from Tuthill Springfield is factory tested; oil drained and shipped dry to its installation point. Both oil reservoirs must be filled to the proper level before operation. In addition to the splash lubrication, booster series incorporating pressure lubrication with a integral oil pump, pressure relief valve, filter and oil-to-coolant heat exchanger.

  • Page 12: Filling Procedure

    5.3.1 FILLING PROCEDURE See Figure 4. Recommended lubricants are shown on page 32. 1. Remove large hex head fill plug from back (non-drive) end cover. 2. SLOWLY pour oil through fill until oil appears in the oil sight glass. Bring oil level to center of sight glass. 3.

    PER 40 CAUTION Factory supplied filters are engineered to provide the proper restriction in the oil lubrication system. Using filters other than those available from Tuthill Springfield may result in lubrication problems and possibly unwarrantable damage to the booster. 5.3.6 OIL PRESSURE ADJUSTMENT...

  • Page 14: Oil Cooler

    5.3.7 OIL COOLER The supply line to the cooler can be connected to either hole. The fluid flowing through the heat exchanger should be sufficient to keep the oil temperature to the optimum operating range of 150-180 °F (65-80 °C). This temperature will insure proper lubrication of the bearings and seals.

  • Page 15: Motor Drives

    5.5 MOTOR DRIVES Two drive connections commonly used are direct drive and V-belt drive. 5.5.1 DIRECT COUPLED When installing the motor directly to the booster, align shafts to coupling in accordance with the coupling manufacturer’s instructions. Boosters shipped with motor directly coupled and mounted on a common base have been aligned prior to shipment and normally no further alignment is necessary.

    However, due to the wide variations in mineral content, pH, and chemical content of water that can be injected, Tuthill Springfield cannot be responsible for damage which may result should this build-up occur. Units should be inspected regularly to determine any problems.

  • Page 22: Maintenance

    7. MAINTENANCE 7.1 GENERAL Regular inspection of your vacuum booster and its installation, along with complete checks on operating conditions will pay dividends in added life and usefulness. Also, service the drive per manufacturer’s instructions and lubricate the coupling or check belt drive tension. By use of thermometers and gauges, make sure that booster operating temperature and pressure remain within allowed limits.
