1.2 Short description
The high pressure filter (hereafter called
“Filter”) ensures in the supply line of an
application layer that no undesired particles
or impurities will arise in the subsequent
process flow. The filter is mounted between
the outlet of a high pressure pump and a
high pressure hose.

4 Assembly
4.1 Requirements for the
Installation point.
It should be possible to disconnect every
power supply to the filter and secure it
against reconnection.
The air supply must be adjustable.
Lines, seals and screw connections must
be designed for the requirements of the
filter.
The filter must be accessible for mainte-
nance work.
Provide pressure release device to avoid
excess pressure.
4.2 Installation position
Install the filter vertically. The filter sump can
face up or down.
Filter sump upwards
Fig. 2: Installation on top (example)
1 Material inlet
The filter is used as compressor. Air presses
up in the filter and keeps the fill level con-
stant. Prevent pressure drops in the con-
nected product and minimize pulsations. Up
to four application devices can be connected
to the connections (2), (3).
If the filter sump is installed above, a
pressure relief valve must be
attached to a connection (2), (3).
Assembly
01/2020 Filter HP - MFT00003EN 7/36
Filter sump downwards
Fig. 3: Installation at bottom (example)
1 Material inlet
The filter can be used for circulation. Air
presses directly through the material outlet
(2) into the high pressure hose. Material run-
ning through the lateral material outlets (2),
(3), (4) is filtered. Material running through
the lower material outlet (5) circulates and is
not filtered. A pressure gage can be con-
nected to the filter on top (2) or on the side
(4).
If the filter sump is installed below, a
pressure relief valve must be con-
nected on the side (4) of the filter.

5 Commissioning
5.1 Safety Instructions
WARNING!
Danger due to missing filter insert
The spring stabilizes the filter insert. If the
filter insert is assembled without spring,
the filter insert can break. This can cause
sparking, which could lead to an explo-
sion. Death or serious injury can result.
– Ensure at the time of assembly that the
spring is inserted in the filter.
– Only put mounted filters into operation.
WARNING!
Danger due to electrostatic charge
If loose parts remain in the filter, sparks
can ignite the explosive atmosphere.
Serious injuries or death can result.
– Ensure before commissioning that
there are no loose parts in the filter.
