Where motor mounted options are to be installed follow manufactures recommended
guidelines. However, when installing a pump complete with base and drive the following
guidelines must be observed:
•
The preferred drive arrangement for any rotary lobe pump is in-line direct coupled.
•
Flexible couplings must always be incorporated and correctly aligned within the limits
recommended by the coupling manufacturer. To check coupling alignment rotate the
shaft by at least one full revolution and ensure that the shaft rotates smoothly.
Couplings of a non-flexible design must never be used.
•
Couplings must always be enclosed in a suitable guard to prevent contact with
rotating parts that could result in personal injury. Guards should be of suitable
material, and of sufficiently rigid design to prevent contact with rotating parts under
normal operating conditions.
•
When installing pump sets in flammable or explosive environments, or for handling
flammable or explosive materials, special consideration must be given not only to the
safety aspects of the drive unit enclosure but also to the materials used for both the
coupling and the guard to eliminate the risk of explosion.
•
Baseplates must be secured to a flat level surface such that distortion and
misalignment are avoided.
Once baseplates are fastened in position the drive
alignment must be re-checked.
•
When using electric motor drives, ensure that the electrical supply is compatible with
the drive and controls and that the method of wiring is correct for the type of starting
required by the motor i.e. Direct On Line, or other similar method. Ensure all
components are correctly grounded.

Installations with CIP Systems
The Acculobe is has been designed to be cleaned effectively by the CIP procedures
recommended for in place cleaning of process equipment. It is recommended that a
differential pressure of 2 to 3 bar (30 to 45 psi) be developed across the pump head
during cleaning in order to develop the necessary fluid velocities required for
thorough cleaning.
