Example of installation
1) YES: gate valve (may also be near pump in the case of long piping)
2) With positive head: tilt of piping towards pump
3) YES: line strainer if particles are present
4) NO: air pockets: the circuit must be short and straight
5) YES: pipe fixing parts
6) Suction line as short and direct as possible
7) YES: check valve (especially for long vertical or horizontal pipes; compulsory with parallel
pumps)
8) YES: adjusting gate valve on outlet
9) Bends placed after valves and instruments
10) YES: attachment for gauge or safety pressure switch
11) NO: elbow joints (and other parts) on the pump (discharge and suction lines)
12) With negative suction lift: tilt of piping towards suction tank
13) YES: check valve (with negative suction lift)
14) YES: strainer if particles are present
15) Suction head varies according to flow in order to prevent windage
16) Suction head
17) Immersion depth
18) YES: expansion joint (indispensable with long pipes or hot liquids) and/or anti-vibration facility during
discharge and suction; anchored near to pump
19) YES: pipe discharge (completely sealed), discharge valve shut during normal operations
20) YES: overcoming obstacles at lower depths
21) Fix the pump by the fixing holes provided: the supports must be level
