Ensure the hose is installed as indicated in Figure 10
Hose and Flange Assembly.
1. Insert the clamp ring over the hose with the large
diameter towards the pump and ensure that the
hose is protruding 5 to 10 mm past the clamp
ring.
2. Fit the O-Ring to the port flange.
3. Apply some lubricant compatible with the pumped
media to the port flange.
4. Make sure the O-Ring is in place in the face
groove and push the port flange into the hose to
-
gether.
5. Install the 4 bolts.
6. Tighten the bolts in a 1–3–4–2 sequence until the
flange is evenly fitted. All 4 bolts should be fitted
to each flange to avoid compromising the perfor
-
mance of the pump.
7. Ensure that the hose can be seen only through
the drain port on the port flange.

8. Run the pump forward and stop when the hose is
protruding 40 mm from the pump housing flange
face. (Figure 10a)
