General Information
3.1. DESCRIPTION
HYGINOX SEN is a range of close-coupled centrifugal pumps with hygienic design, suitable for use in the dairy, beverage, and food processing industry in general.
This single-stage horizontal pump has a circular body with axial suction and tangential discharge. The main pump components are: body, impeller, cover, lantern and a shaft which is rigidly coupled to the motor shaft.
The pump is driven by a NEMA Premium Efficiency C face motor.
3.2. APPLICATION
As a general rule, the most common application of HYGINOX SEN pumps in their standard version is in the food processing industry, mainly to transfer liquids.
For each type of the pump, the hydraulic performance is given by the choice of impeller diameters and speeds. The characteristic curves also show the power and NPSH requirements. The intended use of the pump is defined by its characteristic curve and operating limits provided in the Technical Specifications section.
Misuse of the pump or its use beyond the operating limits may be dangerous or cause permanent damage to the equipment.

Installation
4.1. RECEPTION OF THE PUMP
INOXPA will not be liable for any deterioration of the material due to transport or unpacking. Visually check that the packaging has not been damaged.
The following documentation is included with the pump:
• Shipping documents
• Instructions and Servicing manual for the pump.
• Instructions and Servicing manual for the motor (*).
• (*) If the pump has been supplied with a motor from INOXPA.
Unpack the pump and check the following:
• The suction and discharge connections on the pump, removing any remaining packaging material.
• Check that the pump and motor have not suffered any damage.
• If not in good material condition and/or if not all the parts are included, the shipping carrier should submit a report as soon as possible.
Identification of the pump
Each pump has a nameplate with the basic data required to identify the model.

4.Installation 2021/11
4.2. HANDLING AND STORAGE
HYGINOX SEN pumps are too heavy to be handled and stored manually.
Lift the pump as indicated below:
ATTENTION!
Always remove the motor shroud before hoisting.
4.3. LOCATION
Place the pump in a position that allows enough space around it to provide access to the pump as well as to the motor. (See the Technical Specifications for dimensions and weights).
Place the pump on a flat and level surface.
Install the pump so as to allow proper ventilation.
If the pump is installed outdoors, it must be sheltered under a roof. Its location must allow for easy access during any inspection or maintenance tasks.
4.4. PIPES
• As a general rule, install the suction and discharge pipes in straight sections, with the minimum possible number of bends and fittings in order to reduce as much as possible any pressure losses that may be caused by friction.
• Make sure that the pump’s ports are properly aligned with the pipework and have a diameter similar to that of the pump connections.
• Place the pump as close as possible to the suction tank, if possible below the fluid level, or even below the tank, in order to achieve the largest possible static head for suction.
• Install support brackets for the pipes as close as possible to the pump's suction and discharge ports.
Shut-off valves
The pump may be isolated for maintenance. To accomplish this, shut-off valves must be installed and connected to the pump's suction and discharge connections.
These valves must ALWAYS be open during operation of the pump.
10 4.Installation 2021/11
4.5. ELECTRICAL INSTALLATION
The connection of the electrical motors must be performed by qualified personnel.
Take the necessary precautions to prevent damage to cables and connections.
Electrical equipment, terminals and components of the control systems may still bear electrical current when they are disconnected. Contact with them may be dangerous for operators or cause irreversible damage to equipment.
Prior to handling the pump, make sure that the electrical panel is disconnected.
• Connect the motor in accordance with the instructions supplied by the motor manufacturer.
• Check the direction of rotation.
ATTENTION!
See indicator label on the pump.
Seen from the rear of the motor.
Start and stop the pump motor momentarily. Make sure, looking at the pump from behind, that the motor fan rotates in a clockwise direction.
ALWAYS check the direction of rotation of the motor with liquid inside the pump.

5.1. STARTING THE PUMP
Carefully read Chapter 8.
50H use of the equipment.
Technical Specifications
. INOXPA cannot be held responsible for the improper
NEVER touch the pump or the pipes if hot liquids are being pumped.
Checks before starting up the pump
• Fully open the shut-off valves on the suction and discharge pipes.
• If liquid does not flow into the pump, fill it with the liquid to be pumped.
The pump must NEVER rotate without a liquid inside it.
• Check that the direction of rotation of the motor is correct.
Checks to be carried out when starting up the pump
• Check that the pump is not making any strange noises.
• Check if the absolute inlet pressure is sufficient to prevent cavitation in the pump. Check the curve to determine the minimum pressure required above the vapour pressure (NPSHr).
• Control the discharge pressure.
• Check that there are no leaks through the sealed areas.
Do not use a shut-off valve to regulate the flow in the suction pipe. All shut-off valves must be fully open during operation.
Control the motor consumption to prevent an electrical overload.
12
Reduce the flow rate and the electrical power consumed by the motor:
• by regulating the pump's discharge flow.
• by decreasing the motor speed.
When the sound pressure level in the operating area exceeds 80 dB(A), appropriate personal protective equipment must be used.

Maintenance
7.1. GENERAL CONSIDERATIONS
This pump, just like any other machine, requires maintenance. The instructions in this manual cover the identification and replacement of spare parts. The instructions are aimed at maintenance personnel and those responsible for the supply of spare parts.
Carefully read Chapter 8.
5 1H
Technical Specifications
.
All replaced material should be duly disposed of/recycled according to the directives in force in each area.
ALWAYS disconnect the pump before beginning any maintenance work.
Check the mechanical seal
Periodically check that there are no leaks around the shaft. If leakage is detected through the mechanical seal, replace it following the instructions in the section Assembly and Disassembly.
7.2. STORAGE
Before storing the pump it should be completely drained. Prevent as far as possible exposing the parts to excessively humid environments.
7.3. CLEANING
The use of aggressive cleaning products such as caustic soda and nitric acid may burn the skin.
Wear rubber gloves during all cleaning procedures.
Always wear protective goggles.
CIP (Clean-in-Place) cleaning
If the pump is installed in a system with a CIP process, its disassembly will not be required.
If an automatic cleaning process is not available, disassemble the pump as indicated in the section
Disassembly
.
52H
Assembly and
Cleaning solutions for CIP processes.
Only use clear water (chlorine-free) to mix with the cleaning agents: a) Alkaline solution: 1% by weight of caustic soda (NaOH) at 70ºC (150ºF)
1 kg NaOH + 100 litres of water = cleaning solution or
2.2 litres of 33% NaOH + 100 litres of water = cleaning solution b) Acid solution: 0.5% by weight of nitric acid (HNO

+ 100 litres of water = cleaning solution
14 7.Maintenance 2021/11
Check the concentration of the cleaning solutions; incorrect concentrations may lead to deterioration of the pump seals.
To remove any traces of cleaning products, ALWAYS perform a final rinse with clean water at the end of the cleaning process.
SIP (Sterilization-in-Place) cleaning
Sterilization with steam is applied to all equipment including the pump.
Do NOT use the equipment during the steam sterilization process.
The parts/materials will not be damaged if the indications specified in this manual are observed.
Make sure that no cold liquid enters the system until the temperature of the pump is lower than 60°C
(140°F).
The pump generates an important pressure loss through the sterilization process. We recommend the use of a branch circuit with a discharge valve to ensure that steam / superheated water sterilizes the integrity of the circuit.
Maximum conditions during the SIP process with steam or overheated water a) Max. temperature: 140°C / 284°F
