Before operating the pump, ensure that it and all parts of the system to which it is

connected are clean and free from debris and that all valves in the suction and

discharge pipelines are fully opened. Ensure that all pipe work connecting to the

pump is fully supported and aligned with its relevant connections. Misalignment

and/or excess loads will cause severe pump damage. This could result in

unexpected mechanical contact in the pump head and has the potential to be a

source of ignition.

Ensure that pump rotation is correct for the desired direction of flow.

Do not install the pump into a system where it will run dry (i.e. without a supply of

pumped media) unless it is equipped with a flushed shaft seal arrangement complete

with a fully operational flushing system. Mechanical seals require a thin fluid film to

lubricate the seal faces. Dry running can cause excessive heat and seal failure.

Install pressure gauges/sensors next to the pump suction and discharge connections

to monitor pressures.

Caution must be taken when lifting the pump. Suitable lifting devices should be used

as appropriate. If pump is base plate mounted, the base plate must be used for all

lifting purposes, not any part of the pump. If slings are used for lifting, they must be

safely and securely attached. For weights of bare shaft pumps refer to pump

installation dimensions section.

DO NOT

attempt any maintenance or disassembly of the pump or pump unit without

first ensuring that:

The pump is fully isolated from the power source (electric, hydraulic,

pneumatic).

The pumping chamber and any shaft seal support system, front cover barrier

support system, and rotorcase port barrier support system are de-pressurised

and purged.

Any temperature control devices (jackets, heat-tracing, etc) are fully isolated,

that they are de-pressurised and purged, and components allowed to reach a

safe handling temperature.

DO NOT

loosen or undo the front cover, any connections to the pump, shaft seal

housings, barrier support systems, temperature control devices, or other

components, until sure that such action will not allow the unsafe escape of any

pressurised media.

Avoid any contact with hot parts of pumps and/or drives, which may cause injury.

Certain operating conditions, temperature control devices (jackets, heat-tracing, etc),

bad installation, or poor maintenance can all promote high temperatures on pumps

and/or drives.

When cleaning, either manually or by CIP method, the operator must ensure that a

suitable procedure is used in accordance with the system requirements. For CIP

cleaning requirements, refer to section 3.3.2. The exterior of the pump should be

cleaned periodically.

Surface temperature of pump is also dependent on the temperature of

pumped medium.
