Section 4: Installation
4.1 Uncrating, lifting, and moving
instructions:
After the pump is received, it is important to ensure
compliance with the listed items on the packing slip.
If there is any visible damage, such as dents or
scratches, immediate notification should be made to
the freight carrier and NES Company Inc. It is
important to note that NES does not take
responsibility for damage that occurs during transit
and such damage will not be covered under warranty.
Follow the instructions below when uncrating the
pump.
1. Gently remove the crate lid and packaging material.
2. Dispose of the packaging material properly to avoid
any personnel injuries caused by sharp nails or pointed
objects.
3. Obtain information on the total weight, maximum
outside dimensions, and location of lifting points. If
this information is not available, contact NES
Company Inc.
4. When lifting and moving the pump or pump
assembly, ensure it remains horizontal to the ground.
5. Avoid exerting pressure on the seal water piping,
valves, and other delicate components in the system
with the lifting ropes.
4.2 Piping requirements:
Please confirm that the piping matches the system
drawings provided by NES Company Inc. Also, check
that the pipe sizes and configuration match the
connection sizes on the pump/system. At the
discharge, ensure that there is no back pressure on the
pump

piping and inlet piping. If possible, link the pump
drain connection to the main discharge drain line and
install a gate valve. Ensure the valve remains closed
during Operation and open it when the pump is
turned off to facilitate the flow of seal water out of the
pump.
4.3 Electrical requirements:
Always refer to the motor nameplate to confirm the
motor horsepower and voltage, ensuring it matches
the electrical power source. Consult the relevant data
sheet for the wiring specifications of process valves and
actuators installed in the system.
Section 5: Operations
5.1 Preparation for Initial Start-Up
When commissioning the machine, especially after a
drain or when it is dry, the following steps should be
followed:
5.1.1 Initial Technical Status:
1. Please ensure all lines for pumped gases/vapors are
correctly connected.
2. Close all shut-off fittings and avoid installing shut-
off or non-return fittings on the discharge side.
3. It is necessary to drain the preservative liquid from
the machine and its disposal according to applicable
regulations.
5.1.2 Operating liquid:
Appropriate volume of the operating liquid must be
poured and adjusted as specified in Section 5.3. This is
followed by opening the shut-off valve for the
operating Liquid. Depending on the size of the
machine, this can be done approximately 5 to 15
a
minutes before the start-up. The machine's working
