1.0 General
ELRO®Peristaltic pumps GUP 3-1.5 as well
as GP20/10Ex are dimensioned as pumps
in accordance with chapter 1, article 1, sec-
tion (2), paragraph (j), point (ii) of the pres-
sure equipment directive and are therefore
no pressure equipment as dened by the
EC pressure equipment directive 2014/68/
EEC.
The following instructions refer to the pump
for hazardous materials GUP 3-1,5 acc. to
DIN 14427 and GP 20/10Ex.

Caution!
Since the pumps will be used
in combination with other
assemblies, such as motors,
you must also strictly observe
and comply with the operating
and maintenance instructions
for these components as well as
the corresponding notes on safe
and reliable operation.
These on-hand instructions contain
information for installation, operation and
maintenance of ELRO pumps for hazardous
materials.

Pumps for hazardous materials GUP 3-1,5
and GP 20/10Ex
You should therefore thoroughly read these
instructions before use and always follow the
information contained therein.
All personnel involved in
activities on pump or equipment
associated with the pump
must have read this manual,
especially the chapter ”Safety”
before starting work. This is
too late once work has started.
This applies especially for
persons who work on the
pump only occasionally, e.g. for
maintenance and cleaning work.
You should always bear in mind that a
correct function, a long lifetime and optimal
operational reliability of the pump mainly
depend on
n correct installation
n correct commissioning
n and proper maintenance.
Enquiries concerning service, spare parts
or repairs should be addressed to the
manufacturer or an authorized dealer.
Always provide the following information:
n Type
n Serial number of pump
This information is stamped on the
identication plate on the outside of the
pump.
When returning pumps or pump
parts to the manufacturer or an
authorized dealer for repair or
overhaul, the delivery must be
accompanied by a certicate
stating that the pump is free of
product or other aggressive or
hazardous substances.
1.1 Warranty
The correct function of each ELRO pump
for hazardous materials is checked in the
factory before shipment. The manufacturer
assumes warranty for his product as
specied in the eective terms of sales
and delivery. Faults resulting from the non-
compliance with the regulations and notes
described hereunder can only be rectied at
the cost of the customer.
1.2 Transport
In order to avoid any problems you should
n check the delivered goods against the
delivery note for completeness and
correctness,
n check whether the corresponding
manual for the electric drive has been
included.
Be careful when unpacking the pump and
proceed as follows:
n Examine the packaging for transport
damage.
n Take the pump carefully out of the
packaging.
n Examine the pump for any visible
damage.
Consider the indicated weight
before attempting to lift the
pump. Use only lifting gear of
appropriate capacity.
Do not step or stand under
suspended loads.

Attach the lifting tackle so that the pump
for hazardous materials can be safely lifted
(Fig. 2).
Either fold out the carrier handles and carry
the pump by these handles
or
attach carrier belts or ropes to the eyelets
on the carrier frame and lift the pump with a
hook.
In order to avoid slipping of the
sling the rope (belt) must be
crossed over at the hook.
Fig. 2 Transport of the pump with lifting gear
The priming properties of the peristaltic
pump are based on the vacuum backed
restoring forces of its hose. Due to its paten-
ted design a vacuum is permanently gene-
rated inside the hose on the suction side of
the pump. This vacuum always restores the
hose to its original size.
The abutment 2 (Fig. 3) is an elastomer part
and is installed in the pump section where
the hose is squeezed to maximum extend.
This "soft contact base" of the hose pro-
longs its lifetime considerably.
At the same time this abutment protects the
pump housing against damage caused by
solid particles in case of a hose breakage.
In case of wear the abutment can be easily
replaced.

The sliding tube of the rotor enlarges the
volume of the suction area (4). At the same
time the pressure area (7) is decreased and
the air is forced out through a channel in the
pump cover.
The rotor (1, Fig. 5) rotates inside the
separating part (3, Fig. 5), which is tightly
bolted to the housing. This separates the
suction area (4, Fig. 5) from the inside of the
pump (5, Fig. 5).
The separating part 3 (Fig. 3 and 5)
separates the suction area (4, Abb. 4)
from the inside of the pump (5, Fig. 4) and
protects the pumping hose. In case of hose
breakage it additionally protects the rotor (1,
Fig. 4) against damage caused by abrasive
or coarse particle product. The separating
part can be replaced by simply unscrewing
two screws.
The pump is lled with 1 litre of sliding uid
(glycerine or silicone), which works as
lubricant, barrier and coolant.
The vacuum gauge connected with the
suction area (4, Fig. 4) not only shows the
present suction lift of the pump, but has the
additional function of a warning instrument
for possible defects. If the vacuum gauge
does not indicate a vacuum during
operation, the pump needs to be serviced
urgently.
This maintenance can be carried out without
any special tools.
