Refer to diagrams in this manual for proper rotation and orientation in inlet and discharge. Tuthill Vacuum & Blower Systems model 3200, 4000, 5500 and 7000 Series C-Flange mechanical vacuum boosters are positive displacement type units, whose pumping capacity is determined by size, operating speed, and differential pressure conditions.
Consult your Tuthill Vacuum & Blower Systems sales professional if questions arise. DANGER As with any equipment with rotating elements, the booster will over time become a source of media leaks and a source of ignition.
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 Vacuum & Blower Systems sales representative for specific information. NOTE Special attention must be paid when a vacuum booster has a higher than standard ambient suction temperature.

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.
(See the Motor Drives section for more information.) Boosters from Tuthill Vacuum & Blower Systems 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.
Figure 3 - Illustrations of Soft Foot 5.2 SAFETY Tuthill Vacuum & Blower Systems 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.
5.3 LUBRICATION Every booster from Tuthill Vacuum & Blower Systems is factory tested, oil drained and shipped dry to its installation point. Both independent oil reservoirs must be filled to the proper level before operation. Oil reservoirs are under vacuum.
NOTE Refer to Table 1 for oil capacities. 5.3.1 FILLING PROCEDURE See Figure 4. Recommended lubricants are shown on page 42. 1. Remove fill plugs or breathers from both gear end and drive end plates. 2. SLOWLY pour oil through fill until oil appears in the oil sight glass. Bring oil level to center of sight glass. 3.
package. An indicator of the breakdown of a lubricant is the increase in the TAN (Total Acid Number), and a change in the base viscosity of ten percent. Several things are happening as the lubricant goes through the unit. First, it is absorbing frictional energy in the form of heat.
The partly water-cooled versions (92/93) have cooling INTERCONNECTING water to the seal adapter housing only. The cooling LINES coils and interconnecting water line are omitted and the interconnecting line leading from the seal adapter housing is led to the drain. The air-cooled configuration requires no cooling water.

Proper gap between coupling halves must be established according to coupling manufacturers instructions with the motor armature. This will minimize the change for end thrust on the booster shaft. All direct coupled base mounted units must be re-aligned and greased after field installation. 5.10 MOTOR AND ELECTRICAL CONNECTIONS WARNING The motor and connections shall be protected to assure that product and...
NOTE Be sure not to compress the rubber sleeves or the spider between the couplings or hub halfs. Compression could result in damage or failure. Consult manufacturer’s instructions for approximate gaps between coupling or hubs. 6. OPERATION 6.1 GENERAL DANGER The booster is not intended to be used with explosive products or in explosive environments.
6.2 START-UP CHECKLIST We recommend that these startup procedures be followed in sequence and checked off ( ) in the boxes provided in any of the following cases: • During initial installation • After maintenance work has been performed • After any shutdown period •...
WARNING Physical harm may occur if human body parts are in contact or exposed to the process vacuum. Assure that all connections are protected from human contact. WARNING If rated vacuum or pressure levels are exceeded, process fluids will migrate to other parts of the booster and system.
However, due to the wide variations in mineral content, pH, and chemical content of water that can be injected, Tuthill Vacuum & Blower Systems cannot be responsible for damage which may result should this build-up occur. Units should be inspected regularly to determine any problems.
6.8 RECOMMENDED SHUTDOWN PROCEDURE TO MINIMIZE RISK OF FREEZING OR CORROSION When high humidity or moisture is present in an air piping system, condensation of water can occur after the booster is shut down and the booster begins to cool. This creates an environment favorable to corrosion of the iron internal surfaces, or in cold weather, the formation of ice.
DANGER The booster and connecting piping shall be regularly inspected to assure that process gases are not vented such that a hazard is created. The booster shall also be regularly inspected to assure that the booster and the drive components do not create a source of ignition. CAUTION The electrical service must be isolated and de-energized prior to maintenance.
Personnel should have a good background of mechanical experience and be thoroughly familiar with the procedures outlined in this manual. Major repairs not covered in this book should be referred to the nearest Tuthill Vacuum & Blower Systems service representative.
7.5 LONG TERM STORAGE Any time the booster will be stored for an extended period of time, you should take make sure that it is protected from corrosion by following these steps: 1. Spray the interior (lobes, housing and end plates) with rust preventative. This should be repeated as conditions dictate and at least on a yearly basis.
