INSTRUCTIONS ON INSTALLATION AND USE
8.1 TRANSPORT
-
cover the hydraulic connections
-
when lifting the unit do not exert force on the plastic fittings
-
lay the pump on its base or fixing plate during transport
-
if the road is particularly rough, protect the pump by means of adequate shock absorbing supports
-
bumps and shocks may damage important working parts vital for safety and functionality of the machine
8.2 INSTALLATION
- clean the plant before connecting the pump
- make sure that no foreign bodies are left in the pump. Remove safety caps on the hydraulic connections.
- follow the instructions indicated in the following diagram:
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 (3-5 mm mesh)
4) NO: air pockets: the circuit must be short and straight
5) YES: pipe fixing parts
6) Fluid speed suction: 2.5 m/s
7) YES: check valve (especially for long vertical or horizontal pipes; compulsory with parallel pumps).
8) YES: adjusting gate valve on outlet
9) speed of delivered fluid: 3.,5 m/s max. .
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 (3-5 mm mesh)
15) Suction head varies according to flow in order to prevent windage (min. 0.5 m, max. 15% of pump head)
16) Suction head, 3 m max.
17) Immersion depth: 0.3 m min.
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
22) YES: drainage channel around base
