GENERAL INSTRUCTIONS

The goods must be examined on arrival to ascertain any damage caused during shipment.
Loss or damage must be notified immediately to the carriers and to the sender. Check that
the goods correspond exactly to the description on the shipping documents and report
any differences as soon as possible to the sender. Always quote the pump type and serial
number.
The pumps must be used only for applications for which the manufacturers have
specified:
- the construction materials
- the operating conditions (pressure, speed, temperature, etc.)
- the field of application
In case of doubt, contact Varisco S.p.A.: +39 049 82 94 111

SAFETY AND ACCIDENT PREVENTION INFORMATION

When working near the pump, dress appropriately, avoiding 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, ear plugs and helmet (fig.1).
Do not carry out maintenance on the engine while it is running.
Keep hands away from moving parts (e.g. belts, couplings, etc.).
Do not mount on the pump to carry out maintenance operations of any kind.
5

IN CASE OF EMERGENCY

Turn off the electrical supply (for electrically driven pumps).
Notify the person responsible for running the plant immediately.
6

HANDLING AND TRANSPORT

6.1 Method of transport
The unit must be safely moved and in horizontal way.

6.2 Installation

During installation and maintenance, all the components used
must be handled and transported securely by using suitable
slings. Handling must be carried out by specialised personnel
to avoid damage to the pump and to persons. The lifting points
of the various configurations must be used to lift the unit
only, which must be drained from water and disconnected
from the pipes. Figure 2 highlights in black the lifting points of
some typical base plates.

Maximum lifting speed: Vmax ≤ 0,5 m/s
Do not stand or pass under the pump while it is being
hoisted! (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 and grease the bearings to avoid rusting. (fig. 4).
Avoid the accumulation of moisture around the pump.
Drain the casing through the drain cover (fig. 5) and the rear plug mounted on some models.
During winter months and cold weather, the liquid could freeze and damage the pump
casing. If the liquid is hazardous, take all necessary precautions to avoid damage and
injury before emptying the pump casing. From time to time, turn the pump shaft to avoid
encrustation inside the pump.

ASSEMBLY

If the pump is supplied with bare shaft (pedestal version) it must be coupled to an electric
motor or internal combustion engine, taking account of the following:
- the coupling must be correctly sized for the power to be transmitted
- the coupling must be correctly aligned (see paragraph 10)
- the coupling guard must comply with applicable safety standards
- the rated power of the motor
- the power absorbed by the pump (see the motor name plate)
- the motor or engine speed (see the motor name plate)
- the pump speed
9 INSTALLATION
The base plates of electrically driven pumps must be anchored to a levelled concrete slab in which the foundation bolts have been buried
following the diagram supplied with the unit or available on request. The slab must be robust to absorb any vibrations and sufficiently
rigid to maintain the alignment of the pump to the motor.
9.1 Assembly
While the base plate is being anchored to the slab, check the flatness by placing a spirit level on the delivery flange of the pump.
If adjustments are necessary, the face of the slab must be adapted to the base plate, never the base plate to the slab.
The pump casing must be suitably supported when the pump is coupled to a gear box for agricultural use.
