5.10 FEED PUMP (OPTION)
A feed pump can be used with high-viscosity products or longer feed lines.
Dimensioning of the feed pump
The IceBreaker piston pumps pump the working product to the product output
with up and down strokes but only draw in new product on the up stroke. The feed
pump therefore has to pump twice the volumetric flow.
Main pump protection
The maximum product pressure at the pump inlet of the IceBreaker pump may not
be exceeded.

Protection of feed pump
If the maximum pressure of the feed pump is lower than the maximum pressure
of the main pump, this could be exceeded if the main pump malfunctions. The
feed pump and connection line must therefore be protected from excessive
overpressure. An overpressure valve must then be installed between the feed pump
and main pump.
Observe the flow direction during installation.
