Section 2 - Installation Instructions
2.1 Handling
Carefully unpack the pump. Bare pumps may be lifted with a sling placed around the bearing
housings or under the flanges.
Lift pump-motor assemblies by the baseplate only. Do not attach slings nor hooks to the motor
or the pump as this can cause misalignment. Do not attempt to run the pump until the
installation work is complete.
CAUTION: DO NOT RUN THE PUMP WITHOUT SERVICE LIQUID AND SHAFT
SEAL FLUID.
2.2 Preservation
Cast Iron and Steel pumps are protected internally with a preservative solution applied at the
factory before shipping. The solution should be flushed from the pump prior to use. An MSDS
form is included in the back of this manual (see Appendix A).
The preservative solution is petroleum based and must be disposed of
in accordance with all Local, State, and Federal regulations.
2.3 Mounting
Before operation, the pump package should be carefully set, leveled, and securely bolted in
place. It is recommended that shims and grout be used as necessary under all structural
members of the base.
Graham size 30000 through 50000 vacuum pump assemblies are available with an adapter for
mounting a “C-Face” motor. The pump and support bracket should be bolted to the floor, a
cement pad, or an existing framework.
Baseplates supplied with a pump and drive motor mounted at the factory should be leveled,
shimmed as required, and firmly anchored.
2.4 Installation
All piping to the pump should be adequately supported to eliminate any stress at the pump
connections. All piping joints should be tested for leaks prior to start-up. A temporary start-up
strainer in the process inlet piping may be used to keep large contaminates from entering the
pump at start-up.
