Cooling jacket
The machine can be equipped with cooling jacket.
Pipes and couplings are connected between the cool-
ing jacket and the fixing plate. Cooling water is acces-
sible at the fixing plate.
The fixing plate is provided with five threaded holes
ISO G-3/8 for inspection and change of oil, cooling
water and seal flushing.
For easy handling, the cooling water holes can be
equipped with hydraulic couplings or couplings with
hose clips.
After propeller and jet ring removal, the cooling jacket
is assembled by pushing it from the mixers’ propeller
side on the stator housing. To make it easy, soap
water can be used.
Recommended flow for the cooling water is shown in
the table below. Cooling water temperature 20°C
(68°F).

Cutting rings
Assembling of cutting rings
Center the rotatary cutting ring over the propeller hub.
Use the cutting ring as a jig and drill 4 or 8 holes Ø 4.9
mm, for the rivets.
Fix the cutting ring with the rivets.
If the machine will work with seal flushing, fit the tube
in the stationary cutting ring.
Assemble O-ring, stationary cutting ring and fix the
ring with the 4 screws.
Tightening torque 6—8 Nm.
