4.3- Hoses assembly
Important: Hoses are not included
Use only PVC suction ringed hoses or other hoses with similar quality.
4.3.1- Suction hose
a) Preliminary notes:
Use a commercially available hose, hose connector, and hose clamp.
The suction hose must be of reinforced, non-collapsible wall or wire braided hose to prevent
suction collapse.
The suction hose length should not be longer than necessary, as the pump performance is best when
the pump is not far above the water level.
Self-priming time is also proportional to the suction hose length.
Using a longer suction hose will increase the self-priming time.
The strainer is provided with the pump and should be attached to the end of the suction hose with
a clamp as shown (fig.6)
b) Assembly (Fig.6)
1. Insert the coupling into the suction hose.
2. Use the clamps and tape (not supplied) and tighten firmly.
Then screw the hose coupling to the pump suction inlet [11].
3. Insert strainer in suction hose.
4. Use the clamps and tape (not supplied) and tighten firmly
Remark: always install the strainer on the end of the suction
hose before pumping. The strainer will prevent debris from
entering the pump that can cause slogging or pump damage.
Fig.6
Note: Make sure the washer is properly fitted on the intake hose coupling.
If the washer of the suction hose is loosened, or the hose buckle is lost or damaged, the water will
not be pumped properly due to air leakage
4.3.2- Discharge hose
a) Preliminary notes:
Use a commercially available hose, hose connector, and hose
clamp. A short, large-diameter hose is most efficient.
A long or small-diameter hose increases fluid friction and
reduces pump output.
Tighten the hose band securely to prevent the hose from
disconnecting under high pressure
b) Assembly (Fig.7)
1. Insert the coupling into the discharge hose.
2. Use the clamp and tape (not supplied) and tighten firmly.
Then screw the hose coupling to the pump discharge port [12].
