ED. 16.3/98 4. Estampinox Installation 4.1
4. Installation
GENERAL CONSIDERATIONS.
This manual provides basic instructions which should be taken into account when proceeding to install the pump. It is of utmost
importance that the shop foreman read this manual before assembly.
LOCATION.
Piping.
Place the pump as close as possible to the suction tank (refer to the chapter, "Pump Installation"), and if possible below the level of
the liquid or even lower in relation to the deposit so that the static manometric suction head is at its maximum. Place the suction and
discharge piping in straight runs with a minimum of elbows and fittings in order to reduce to the extent possible any loss of head
caused by friction. This improves the suction conditions, thereby affording maximum performance of the pump.
Accessibility.
Place the pump so that access can be had to the pump and to the drive units so as to make inspections and revisions. Leave
sufficient space around the pump for proper inspection, separation of the pump from other units and for maintenance operations. In
order to disassemble the pump you should leave sufficient space in front of and behind it. (Chapter 9 deals with the dimensions).
Place the pump near the drain on the floor.
It is very important to be able to gain access to the pump connecting device (including when it is operating).
Excessive temperatures.
Depending on the fluid to be pumped, high temperatures can be reached inside and around the pump.
Over 70 ºC the operator should take protective measures and place warning notices advising of the
danger which exists if the pump is touched. The type of protection selected should not isolate the pump
entirely. It should allow for optimum cooling of the motor.
STABILITY.
Foundation.
Prepare the foundation so that the pump is level and well supported. Its emplacement should be rigid, horizontal, flat and resistant
to vibrations, so as to avoid any warping (if the pump's alignment is maintained its operation is ensured during start-up).
HANDLING.
If the pump is supplied without a motor, the purchaser/user is responsible for the pump's start-up and
assembly.
ELECTRIC MOTORS.
Regulations.
Prior to connecting an electric motor to the power supply, check local regulations on electrical safety and also refer to the EN
60204-1 standard.
Let qualified personnel perform the connection of electrical motors. Take the necessary steps to prevent
faults in the connections and wiring.
Protection of the motor against overloads.
In order to protect the motor from overloads and short circuits, the use of thermal or magnetic relays is recommended. Adjust these
relays to maximum rated current values as indicated on the data plate of the motor.
Connection.
Consult the supplier's instructions prior to connecting the motor to the power net.
For single-phase motors, use motors with an increased starting torque.
Ensure a starting torque which is sufficiently high for motors controlled by a frequency changer, and which provide for adequate
cooling at low speeds. If necessary, install an independent fan.
The electrical equipment, the terminals and the control system components can continue to carry
current when disconnected. Any contact with them can endanger the safety of the operators or cause
irreparable damage to the material.

4. Estampinox Installation 4.2 ED. 16.3/98
DIRECTION OF ROTATION.
The direction of rotation is clockwise viewing the pump from the rear part of the motor.
Make sure that the pump rotates in the direction indicated on the plate. If the pump rotates in the
wrong direction its hydraulic performance will be lower.
Electrical diagram.
Figure 4.1: Electrical Connections
SUCTION AND DISCHARGE PIPES.
Pipes.
Use pipes with a diameter which is equal to or greater than that of the pump's connections. If the liquid to be pumped is viscous, the
loss of head from the suction and discharge pipes can increase considerably. Other pipe components such as valves, elbows, filters
and foot valves, can also cause a loss of head.
For this reason, the diameters and the length of pipes and other components should be selected so that the pump will operate within
the minimum pressure limits allowed for the suction (refer to NPSH graph), the maximum working pressure (refer to chapter 3,
"Field of Application"), and the rated motor power.
Suction pipe.
Liquids should be introduced into the pump from a higher level than that of the pump; the pipe should be inclined in its path to the
pump and devoid of air pockets.
If a filter is installed in the suction mouth, a constant check for loss of load in the suction pipe should be made. Also check to see
whether the suction pressure at the suction mouth of the pump is sufficiently high (see NPSH).
Check the tension of the suction pipe after its connection.

ED. 16.3/98 5. Estampinox Start-Up 5.1
5. Start-up
GENERAL CONSIDERATIONS.
The pump can be started up so long as the instructions given in chapter 4 ("Installation") have been followed.
Prior to start-up, the persons responsible for the operation must be duly informed of the pump’s
operation and the safety instructions. This instruction manual should be available to personnel at all
times.
Prior to start-up, check the pump for any possible failure. If a failure is found, the plant foreman should
be notified immediately.
Also consult the section "Dimensions" in chapter 9.
CLEANING.
Prior to start-up, check to see that the pipes and the pump are completely clean and devoid of weld
spatterings or other foreign particles.
Consult chapter 10 (cleaning and disinfection) on how to properly clean the pump and the methods and liquids which should be
used.
START-UP.
•Completely open the shut-off valves in the suction and discharge pipes.
•If the liquid does not flow into the pump, fill it with liquid when pumping.
The pump should never rotate when empty.
•Check to see if the pump can be started up safely.
•Start the pump.
•Check to see whether the absolute suction pressure is sufficient, so that vapour cannot be produced inside the pump. Refer to the
curve for the minimum pressure required above the vapour pressure (NPSH).
•Control the discharge pressure.
A shut-off valve should not be used in the suction pipe to regulate the flow rate. It must be completely
open during operation.

ED. 16.3/98 6. Estampinox Maintenance 6.1
6. Maintenance
GENERAL CONSIDERATIONS.
Inadequate, wrong or improper maintenance could result in the faulty operation of the pump, high repair
costs, and breakdown in the long run. For this reason the instructions given in this chapter should be
followed.
During maintenance operations which are performed on the pump, whether due to inspections, preventive
maintenance or the movement of the installation, the procedures indicated should always be followed.
Failure to comply with these instructions could endanger the operator and/or seriously damage the pump.
Maintenance work should only be done by qualified personnel. Wear appropriate clothing which provides
adequate protection against high temperatures and hazardous and/or corrosive fluids. Make sure that the
personnel read the entire instruction manual and, in particular, indicate to them the chapters which refer
to work which needs to be done.
INOXPA does not assume responsibility for accidents and damage which might occur as a result of any
failure to comply with the instructions indicated herein.
CONSERVATION.
Should the pump be taken out of service for a long period of time:
•First of all, empty the pump.
•Apply VG46 mineral oil to the internal parts.
•The pump should be worked on for a brief period of time once a week or the shaft rotated manually. This ensures the correct
circulation of the protective oil.
EXTERNAL CLEANING.
Attempt to keep the exterior of the pump clean at all times. Cover all parts which should not enter into contact with the cleaning
fluid.
Do not spray hot parts of the pump with water as some components could crack due to quick cooling and
the fluid inside the pump could spill out.
ELECTRICAL INSTALLATION.
Maintenance work on electrical installations can only be done by qualified personnel and only when the
power supply has been cut off. Carefully follow national safety regulations.
MAINTENANCE.
Periodically check suction and discharge pressures.
Inspect the motor in accordance with the manufacturer's instructions.
In general, a mechanical seal does not require maintenance; however, the seal should never be made to work when empty. Should a
leak occur, replace the seal.
