SAFETY RULES AND ACCIDENT PREVENTION

When working near the pumping unit, dress appropriately, avoiding baggy clothes with
loose items (ties, scarves, etc.), which could get caught in moving parts. Use overalls
made according to safety regulations, gloves, insulating shoes, safety glasses, safety
earmuffs and hard hat (fig.1). Internal combustion engines are fitted with mufflers, but the
sound emission level is still high enough to make use of ear protection (PPE) by all
operators compulsory.

Do not carry out maintenance on the engine while it is running.
Keep hands away from moving parts (e.g. belts, couplings, etc.).
Keep hands away from parts of the engine that get hot.
Do not climb on top of the pumping unit to perform work of any kind.

5

IN CASE OF EMERGENCY

Disconnect mains power (for motor pumps).
Shut off the engine (for engine-driven pumps).
Notify the person responsible for running the plant.

6

HANDLING AND TRANSPORT

6.1

Method of transport

The unit must be transported horizontally and safely

6.2

Installation

During installation and maintenance, all components used
must be handled securely using suitable slings. Handling
must be carried out by specialized personnel to avoid damage
to the pump and injury of personnel.
The lifting points of the various components should be used
to lift the pumping unit only. 
The lifting points of a few sample base plates are highlighted
with a heavy black mark in figure 2.

Maximum lifting speed: Vmax 

0,5 m/s

Do not linger or pass under the pump while it is
lifted! (fig. 3)

7

STORAGE

Store the pump under cover wherever possible. If the pump
must be stored in the open, cover it with a tarpaulin, lubricate
bearings to prevent rust (fig. 4).
Prevent moisture from building up around the pump.

7.1

Do not leave liquid in the pump casing. Drain by
unscrewing the drain plug (16) in (fig. 5). During winter
months and in cold weather, the liquid could freeze and
damage the pump. If the liquid is hazardous, take all
necessary precautions to avoid damage and injury.
At regular intervals, turn the shaft to prevent encrustation
inside the pump.

ASSEMBLY AND COUPLING

If the pump is supplied in the bare shaft version (pedestal pump), it must be coupled to the
engine, taking account of the following:

-

the coupling must be suitable for the power to be transmitted.

-

the coupling must be aligned properly (see sect. 10).

-

the coupling guard must comply with applicable safety standards.

-

rated power of the engine.

-

power absorbed by the pump (see engine's rating plate).

-

engine speed (see engine's rating plate).

-

pump speed.

9

INSTALLATION

The base plate of the engine- or electrically-driven pump unit must be anchored on a levelled concrete slab into which anchor bolts have
been embedded following the layout supplied with each unit, or available on request. The slab must be heavy duty to absorb any vibration
and rigid enough to maintain the alignment of the pump to the motor or engine

9.1

Assembly

When anchoring the base plate to the slab, we recommend you check levelness with the aid of a level placed on top of the pump delivery
port flange.
If adjustments are required, always adapt the surface of the slab to the base plate, and 

never

the base plate to the slab.
