• Before starting the pump check the tightness of the screws of the pump bodies and manifolds.
• The pump positioning is horizontal, the fluid delivery manifold must always be positioned in the
upper part (see arrows on the pump casing).
• Fastening may be on the floor or on the ceiling.
• Position the pump the closest possible to the extraction point.
Use the installation applications indicated in the following diagram
1. YES: use flexible pipes reinforced with rigid spiral to connect the hydraulic circuit of the pump.
Rigid piping may cause strong vibrations and manifolds breaking. Do not use pipes with nominal
diameter smaller than the diameter of the pump connections. For negative installations and/or viscous
fluids use pipes with greater diameter related to the nominal diameter of the pump.
2. YES: pulse damper
3. YES: gate valve for delivery adjustment
4. YES: intake for gauge or protection pressure switch
5. YES: pipe anchoring
6. YES: shut-off valve
7. NO: air pockets; the circuit must be linear and short
8. YES: discharge duct around the base
9. YES: wide and rigid filtering separator in case of open tanks
10. YES: wide and rigid filtering separator in case of open tanks
11. The length of the horizontal S as short as possible,
12. Slope of the pipe to the pump
13. The flow velocity of the fluid max. 3.5 m / s
