Electical connections
The installer is responsible for making the electrical connections to the main
power supply in compliance with the relevant regulations in force.
Note that international regulations demand that fixed installations
incorporate a device ensuring Omni polar disconnection from the main power
supply.
Make sure that the specifications on the pump rating plate and the rated line
values are the same (Fig.D).
Connect the pump to an effective earth circuit and then connect up the phases
following the diagram on the terminal block cover rating plate.
Check that three phase pumps stage clockwise when looking at the pump from the
motor fan side, swapping over two of the phase connections if they do not.
CONDITIONS OF PROPER USE
The pump may maintain normal and continuous operation in following conditions:
- Maximum Ambient Temperature : + 40 oC
- Maximum Water Temperature: + 60 oC
- Maximum Operating Pressure: 8 bar
- Maximum Altitude + 1000m
- The pump must be earthed safely.
- The pump must be set on a dry base.
- Do not operate the pump without water.
- The pump only use for pumping clean water or liquids similar to water without sands.
OVERVIEW OF PUMPS
A. AUTOMATIC SELF-PRIMING WATER PUMP:
These pumps are equipped with automatic functions. It means that when output
valve opens, the pump operates and vice versa.
B. SELF-PRIMING WATER PUMP:
These pumps have monolithic structure and self-priming function with high
hydraulic performance and a considerable pressure capacity.
C. CENTRIFUGAL WATER PUMP:
These pumps with large output flow, can provide table operation and low noise;
Most of pumps use for irrigation purpose.
D. PERIPHERAL WATER PUMP:
These pumps with feature of simple structure but with high head its efficiency
is low.
E. MULTILEVEL WATER PUMP:
These pumps with several impellers which to be able to develop high pressure
and highwater lift but with low power consumption.

- The manufacturer reserves the right to make minor changes to product design and technical specifications without prior notice unless these changes significantly affect the performance and safety of the products. The parts described / illustrated in the pages of the manual that you hold in your hands may also concern other models of the manufacturer’s product line with similar features and may not be included in the product you just acquired.
- To ensure the safety and reliability of the product and the warranty validity, all repair, inspection, repair or replacement work, including maintenance and special adjustments, must only be carried out by technicians of the authorized service department of the manufacturer.
- Always use the product with the supplied equipment. Operation of the product with non-provided equipment may cause malfunctions or even serious injury or death. The manufacturer and the importer shall not be liable for injuries and damages resulting from the use of non-conforming equipment.
INSTALLATION
The pumps must be installed in a dry well-ventilated place with an ambient
temperature of not more than 40oC (Fig.A). Fix the pump in place on a solid
flat surface using suitable bolts to avoid vibration. The pump must be
installed in a horizontal position to ensure that the bearings operate
correctly. The diameter of the intake pipe must not be smaller than that of
the intake month. If the intake height exceeds 4 meters, use a pipe with
larger diameter. The diameter of the delivery pipe must be chosen to suit the
flow rate and pressure required at the take off points. The intake pipe must
be slight angled up towards the intake mouth to avoid the formation of air
locks (Fig.B). Make sure that the intake pipe is completely airtight and
immersed in the water by at least half a meter to avoid the formation of
vortexes. Always fit a foot valve at the end of the intake pipe. It is
advisable to fit a non-return valve between the delivery mouth and flow rate
adjustment gate valve to avoid dangerous water hammering in the event of the
pump suddenly stopping. This measure is compulsory if the delivery water
column is over 20 meters.
The pipe muse always be fitted using the related brackets (Fig.C) to avoid
transmitting stress to the pump body. Take care not to damage any part by over
tightening the pipes when fitting them.
Fill the pump completely with clean water before switching it on. The water
should be poured in through the priming plug (Fig.F). When you have completed
the operation screw the plug back in again and start the pump. The pump should
be primed again whenever it has not been used for a long period of time or
when air has made its way into the system.
MAINTENANCE
**** NEVER CARRY OUT ANY WORK ON THE PUMP WITHOUT HAVING FIRST DISCONNECTED
IT FROM THE MAIN POWER SUPPLY. FAILURE TO TAKE THE FOLLOWING PRECAUTIONS COULD
DAMAGE YOUR PUMP AND INVALIDATE THE GUARANTEE.
Our pumps do not require any maintenance provide one takes the following
precautions:
When there is a risk of freezing empty the pump through the drain plug on the
bottom of the pump body. Make sure your prime it when subsequently starting it
again.
Check that the foot valve is clean at regular intervals.
If the pump is to remain unused a long period of time (e.g. in the water )
(Fig.G), it is advisable to empty it completely rinse it with clean water and
store it in a dry place.
If the shaft does not turn freely, release it using a screw driver inserting
it in the special slot (Fig.H). If this is nor sufficient to solve the problem
,remove the pump body, undoing the relevant mounting bolts, and clean it
thoroughly to remove any encrustation .
