5.2.7 SCOPE OF DELIVERY
Pump can be delivered as a complete pump set including electrical
motor, flexible coupling, coupling guard and baseplate. It can be also
delivered without one of those parts. A CE integration certificate is then
supplied.
This instructions and operating manual is part of the pump supply and
should be delivered attached to the pump. If not, ask SALMSON
Customer department to get it.
ATEX pumps may be delivered with specific instrumentation. Refer
to pump technical datasheet or to acknowledgment of order to
know exhaustive scope of supply.

6 DESCRIPTION AND WORKING PRINCIPLE
6.1 PRODUCT INFORMATION
NESE pump is a single stage PN40 volute casing pump designed for
M
horizontal installation. Dimensions meet ISO2858 requirements.
The back pull‐out design of the bearing assembly permits dismantling of
790
the impeller while suction and discharge lines are fastened to casing
950 flanges.
If a coupling spacer is used the motor won't have to be moved rearward
1040
during maintenance operation.
1110
This pump is designed to handle overheated water up to 230°C.
A silicon carbide bearing located behind the impeller reduces the
1190
overhang. Mechanical seal is located close to the ball bearing assembly.
1300
Two lamination areas separate mechanical seal chamber from
1610
overheated water. Thanks to this specific design the fluid temperature is
limited to 100°C at mechanical seal and allows a standard sealing
without external cooling. A fourpoints contact ball bearing that carries
M
heavy axial loads is integrated in the bearing assembly.

6.2 FUNCTION
1110
NESE pump is a centrifugal pump with axial inlet and radial outlet.
Depending on required discharge pressure the pump speed can be
1190
1450 or 2900 RPM.
1300
An impeller turns inside the pump casing (direction of rotation is
1610
clockwise seen from drive end). The rotation movement is
transmitted to the fluid that is driven to the vanes and then pumped
1850
to the discharge flange where it leaves the pump. In the flow
passage of the pump casing the kinetic energy of the fluid is
converted into pressure energy.
NESE pumps are not self‐priming pumps. Suction line and pump
M
casing should be completely filled with liquid before pump start.
When necessary or when a maximum pumping efficiency is required
several possibilities are offered to adapt capacity/pressure.
890
Modification of the system hydraulic characteristics :
1110
A regulating valve is added at the discharge side of the pump. The
hydraulic loss can be adjusted and so the pump duty point.
1250
Modification of pump characteristics :
1400
Use of a frequency inverter gives the possibility to adjust pump
1560
speed. The pump hydraulic curve is modified to reach required duty
point but impeller diameter is unchanged.

Location will be chosen to ensure space reservation for maintenance
and inspection.
Check that there is ample overhead for lifting and that lifting devices are
available.
