(viii) When installing a pump complete with baseplate, motor and drive the
following guidelines must be observed:
a)
The preferred drive arrangement for any rotary lobe pump is in-line direct
coupled. If an alternative is required please contact Viking Pump or your
Viking Pump distributor.
b)
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.
c)
Couplings must always be enclosed in a suitable guard to prevent contact with
rotating parts which could result in personal injury. Guards should be of
suitable material ,(see d) and of sufficiently rigid design to prevent contact
with rotating parts under normal operating conditions.
d)
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.
e)
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, (see b).
f)
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.
3.3.2 Installations with CIP Systems.
The
Duralobe ® has been designed to be effectively cleaned by the CIP
procedures recommended for in place cleaning of process equipment. It is
recommended that a differential pressure of 30 to 45 psi be developed across
the pump head during cleaning in order to develop the necessary fluid
velocities required for thorough cleaning.
3.4
Start Up Procedure.
- Check that all piping and associated equipment are clean and free from
debris and that all pipe connections are secure and leak free.
- For pumps installed with flushed product seals check that all auxiliary
services are in place and connected and provide sufficient flow and
pressure for flushing purposes, refer to section 4.3.7.
