5.2.3 DIRECTION OFROTATION
Serious damage can result if the pump is started or run in the
wrongdirectionofrotation.
Ensurethatthedirection of rotation is correctbeforefirst start‐up or if
maintenanceworkhasbeencarriedoutontheelectricpowersupply.
Direction of rotation must correspond to the arrow attached or
engravedinthepu
mp.
Check direction of rotation when motor is apart (coupling spacer
dismantledormotornotcoupledtopump).Ifnotfeasibleduetopump
design (pump fitted with rigid coupling) it is necessary to check that
pumpshaftturnsfreelyafterthetestandbeforefinalpumpstart.
Toch
eckdirectionofrotationstart motorbriefly and checkdirection of
rotation just before rotation stops. If direction of rotation must be
modifiedthenreversetwophasesinmotorjunctionbox.

6 DESCRIPTIONANDWORKINGPRINCIPLE
6.1 PRODUCTINFORMATION
S pump is a single stage self priming pump. Several variants of
construction are available: close‐coupled (without shaft coupling),
Biblockorwithballbearingsassemblyfittedwithelasticcoupling.
Close‐coupled pumps use a long shaft electric motor. Biblock pumps
accept flanged normalized IEC motor. Other pumps sets use IEC B3
mot
ors. 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
valveintegratedinthesuctionflangeassembly.
Zinc anodes or internal coating with Ce
ram C0 can be supplied as an
optionforspecificapplications.
