Rotating parts
Do not tamper with the protection of the rotating parts, do not touch or approach rotating
parts in movement.

Cleaning and disinfection
Cleaning and disinfection of the pump system is of greatest importance when the pump is
used in a food process installation. Use of a pump system that is NOT cleaned or disinfected
can cause contamination of the product.

Example of installation
1)
YES: Gate valve (may also be near pump in 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 fastening
6)
Suction line as short and direct as possible
7)
YES: attachment for gauge or safety pressure switch
8)
YES: adjusting gate valve on outlet
9)
Bends placed after valves and instruments not closer to the pump inlet than five times the piping diameter
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: overcoming obstacles at lower depths
20)
Fix the pump by the fixing holes provided: the supports must be level
21)
YES: drainage channel around base
