4.1.2.
Ball cup valves
This option is a perfect solution when there is risk of damage
to the valve seats from the product. If such situation is to occur
there is no need to replace the whole manifolds or housings,
just the valve cup what drastically reduces the spare parts cost.
Just like the flap valve it is made of AISI 316L stainless steel and
is mounted between the housing and manifold with clamps. In
the same way the manifolds (pos.131 and 132), pump housing
(pos.11) and pump stand (pos. 17) has to be changed in
comparison to a standard sanitary pump.

4.2.
Heating jacket
The heating jacket is a great option when the pumped product
tends to solidify at lower temperatures e.g. chocolate or paraffin.
When the pump has finished its duty and is left for some time
without operation the product can solidify inside. This is when
the heating jacket comes in. Before next pump start-up heating
medium like water or steam is into the heating system for a
defined period of time to melt the product inside the pump.
Only then can the pump be started again with no risk of damage.
Recommendations:
➢
When using steam as the heating agent the flow must be
from top to bottom (due to steam condensation). In case
of hot water or other liquid it is the other way around.
➢
Do not exceed
2 bar
pressure in the heating jacket.
