When installing a pump complete with base plate, 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 the pump is installed in a flammable or

explosive environment, or is used 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) Base plates must be secured to a flat level

surface such that distortion and misalignment

are avoided. Once base plates 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 Classic+ pump range is designed to be effectively cleaned

by the CIP procedures recommended for in place cleaning of

process plant. 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.

Observing the following general guidelines should ensure the

best possible suction condition is created.
- Suction piping is at least the same diameter as the pump

connections.

- The length of suction piping is kept to the absolute

minimum.

- The minimum number of bends, tees and pipework

restrictions are used.

- Calculations to determine system NPSHa are carried out for

the worst condition see below.

Should advice on pump or system NPSH characteristics be

required contact the factory or their authorized distributor.
