All warnings in the manual are summarized on thispage.

Pay special attention to the instructions below so thatsevere personal injury and/or damage to the pumpare avoided.

Safety

Always read the technical data thoroughly (seepage 22).

Always use a lifting crane when handling the pump.

Always have the pump electrically connected byauthorized personnel (see the motor instructions).

Pump without impeller screw:- Always remove the impeller before checking

the direction of rotation.- Never start the pump if the impeller is fitted

and the pump casing is removed.Pump with impeller screw:- Never start in the wrong direction of rotation

with liquid in the pump.

Never touch the pump or the pipelines whenpumping hot liquids or when sterilizing.

Never run the pump with both the suction sideand the pressure side blocked.

Always handle lye and acid with great care.


Always disconnect the power supply whenservicing the pump.

- Never service the pump when it is hot.- Never service the pump with pump and pipe-

lines under pressure.

1. Unpacking/Delivery

Remove possible packing materials from the inletand the outlet.

InstallationThe instruction manual is part of the delivery.Read the instructions carefully.The standard delivery does not include the testcertificate. This can be supplied on request.

The large pump sizes are very heavy.Alfa Laval Flow Inc. therefore recommends the useof a lifting crane when handling the pump.

Avoid damaging the inlet and the outlet.

Remove packingmaterials!

Avoid damaging the connections for flushingliquid, if supplied.

Always use a lifting crane when handlingthe pump (see technical data).

CAUTION!Alfa Laval Flow Inc. cannot be held responsiblefor incorrect unpacking.

Check the delivery for:1. Complete pump.2. Delivery note.3. Motor instructions.4. Test certificate, IF ORDERED!I

The large pump sizes are very heavy.Alfa Laval Flow Inc. therefore recommends theuse of a lifting crane when handling the pump.

Read the instructions carefully and pay specialattention to the warnings!Always check the pump before operation.- See pre-use check on page 6.

Ensure that there is sufficient clearance aroundthe pump (minimum 2 ft).

2. Installation

1. Ensure that the pipelines are routed correctly.2. Ensure that the connections are tight.

Installation

Always use a lifting crane when handlingthe pump (see technical data).

Always have the pump electricallyconnected by authorized personnel (seethe motor instructions).

CAUTION!We cannot be held responsible for incorrectinstallation.

Always read the technical data thoroughly(see page 22). 77

Pmax = 14.5 psi (water) Control:Reduce the capacity and the power consumptionby means of:- Throttling the pressure side of the pump.- Reducing the impeller diameter.- Reducing the speed of the motor.

Throttling!

Problem Cause/result Remedy

Overloaded motor - Pumping of viscous liquids- Larger motor or smaller

- Pumping of liquids with high impellerdensity

- Low outlet pressure - Higher counter pressure(counter pressure) (throttling)

- Lamination of precipitates - Frequent cleaningfrom the liquid

Cavitation:

- Damage - Low inlet pressure - Increase the inlet pressure

- Pressure reduction - High liquid temperature - Reduce the liquid temperature(sometimes to zero)

- Reduce the pressure drop- Increasing of the noise level before the pump

- Reduce speed

Leaking shaft seal Replace:- Dry run All wearing parts (See page 10)

(See page 7)If necessary:

- Incorrect rubber grade - Select a different rubber grade

- Abrasive particles in the - Select stationary and rotatingliquid seal ring in Silicon Carbide/

Silicon Carbide

Leaking seals Incorrect rubber grade Replace with seals of a differentrubber grade

Pay attention to possible faults. Read the instructions carefully.
