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
NOEH pump is a single stage PN16 or PN20 volute casing pump designed
for horizontal installation. Dimensions meet ISO2858 requirements. Its
mechanical design is according to ISO5199.
The back pull ‐ out design of the ball bearing assembly permits
dismantling of the impeller while suction and discharge lines are
fastened to casing flanges.
If a coupling spacer is used the motor won’t have to be moved rearward
during maintenance operation.
This pump is designed to handle overheated water up to 180°C thanks to
a specific shaft sealing arrangement and auxiliary system.
The bearing bracket is equipped with angular contact oil lubricated ball
bearings on drive side to handle most demanding applications.
6.2 FUNCTION
NOEH pump is a centrifugal pump with axial inlet and radial outlet.
Pump speed is 1450 RPM.
An impeller turns inside the pump casing (direction of rotation is
clockwise seen from drive end). The rotation movement is transmitted
to the fluid that is driven to the vanes and then pumped 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.
NOEH pumps are not self ‐ priming. Suction line and pump 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.
Modification of the system hydraulic characteristics :
A regulating valve is added at the discharge side of the pump. The
hydraulic loss can be adjusted and so the pump duty point.
Modification of pump characteristics :
Use of a frequency inverter gives the possibility to adjust pump speed.
The pump hydraulic curve is modified to reach required duty point but
impeller diameter is unchanged.
7 INSTALLATION AND ELECTRICAL
CONNECTION
7.1 LOCATION
Equipments that will be used in a ATEX zone should be
certified accordingly and should fully comply with applicable
regulations.
The choice of the pump location should permit a proper cooling of the
motor and should respect following limits :
