5.2.3 DIRECTION OF ROTATION
Serious damage can result if the pump is started or run in the
wrong direction of rotation.
Ensure that the direction of rotation is correct before first start‐up or if
maintenance work has been carried out on the electric power supply.
Direction of rotation must correspond to the arrow attached or
engraved in the pump.
Check direction of rotation when motor is apart (coupling spacer
dismantled or motor not coupled to pump). If not feasible due to pump
design (pump fitted with rigid coupling) it is necessary to check that
pump shaft turns freely after the test and before final pump start.
To check direction of rotation start motor briefly and check direction of
rotation just before rotation stops. If direction of rotation must be
modified then reverse two phases in motor junction box.
It is possible to change two phases in the control cabinet on motor
starter connections. If this solution is preferred then it will be
necessary to modify the identification of the cables in the electrical
drawings too.
5.2.4 NOISE LEVEL
Noise level of a complete pump set depends on motor type and speed,
on quality and wear of flexible coupling (if concerned), on fluid velocity,
piping design, ... Values given hereafter are only indicative and based on
fan cooled electric motors average noise levels.
The test must be performed on the supplied pump if the noise
level must be certified.
If noise level is higher than 85dBA, personel working in pump area
should wear hearing protections.

5.2.5 CONNECTIONS
 Suction flange axis is horizontal and the face is vertical.
 Discharge flange axis is vertical and the face is horizontal.
5.2.6 PERMISSIBLE FORCES AND MOMENTS
No other stress than the one due to fastening of pipe and pump
flanges together should apply. No stress must be applied to pump
casing by the pipe work. A pre‐stress may exceptionally be applied to
flanges to compensate a pipe expansion. But in any case the resulting
forces should not exceed values given hereafter :
Applied forces and moments should not be maximum at the same
time.
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
S pump is a single stage self priming pump. Several variants of
construction are available : close‐coupled (without shaft coupling),
Biblock or with ball bearings assembly fitted with elastic coupling.
Close‐coupled pumps use a long shaft electric motor. Biblock pumps
accept flanged normalized IEC motor. Other pumps sets use IEC B3
motors. Diesel or gasoline engines can be used for mobile or fixed
installations.
S pumps include an open impeller, wear plate(s) (rear and front wear
plates according to pump size), single mechanical seal and non‐return
valve integrated in the suction flange assembly.
Zinc anodes or internal coating with Ceram C0 can be supplied as an
option for specific applications.
