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.

DESCRIPTION AND WORKING PRINCIPLE
6.1 PRODUCT INFORMATION
NOLH pump is a single stage PN16 volute casing pump designed for
horizontal installation. Hydraulic characteristics and dimensions meet
EN733 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 clear or slightly turbid fluids with non
particle content.
Foreign matter can occasionally pass through the pump but their size
should be limited to 3mm (depending on pump size) but pump lifetime
will be shortened.
6.2 FUNCTION
NOLH pump is a centrifugal pump with axial inlet and radial outlet.
Depending on required discharge pressure the pump speed is 1450 or
2900 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.
NOLH pumps are not self‐priming pumps. 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.
