ELRO®Peristaltic Pumps Series M300 / T300

1.0 Introduction
ELRO®Peristaltic pumps M300/T300 are dimen-
sioned as pumps in accordance with chapter 1,
article 1, section (2), paragraph (j), point (ii) of the
pressure equipment directive and are therefore
no pressure equipment as dened by the EC
pressure equipment directive 2014/68/EEC.
The following instructions refer only to the peri-
staltic pumps M300 and T300.
Since the pumps will be used in
combination with other assem-
blies, such as combustion engines
and electric 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 opera-
tion.
These instructions contain information for in-
stallation, operation and maintenance of peri-
staltic pumps ELRO M300 and T300.
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 must have
read this manual, especially the
chapter ”Safety” before starting
work. This is too late once work
has started. This applies especial-
ly for persons who work on the
pump only occasionally, e.g. for
maintenance and cleaning work.
Each pump is subject to stringent inspections
and function tests before leaving the factory.
You should always bear in mind that a correct
function, a long lifetime and optimal opera-
tional reliability of the pump mainly depend
on
ncorrect installation
ncorrect commissioning
nand proper maintenance.
Enquiries concerning service, spare parts or
repairs should be addressed to the manufac-
turer or an authorized dealer.
Always provide the following information:
n Pump type
nSerial number of pump
This information is stamped on the identica-
tion plate on the base 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 (see page 37).
1.1 Warranty
The correct function of each ELRO peristaltic
pump is checked in the factory before ship-
ment. 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 aforemen-
tioned regulations and notes can only be
rectied at the cost of the customer.

1.3 Function
The priming properties of the peristaltic
pump are based on the vacuum backed
restoring force of its hose. Due to its special
design a vacuum is permanently generated
inside the hose on the suction side of the
pump. This vacuum always restores the
hose to its original size. This way the pump
achieves maximum pumping power.

1.2 Transport, storage
In order to avoid any problems you should
ncheck the delivered goods against the
delivery note for completeness and cor-
rectness,
nmake sure that for pumps with electric
motor, combustion engine, water tur-
bine, hydraulic motor or pneumatic mo-
tor the respective operating instructions
for the drive are available.
Be careful when unpacking the pump and
proceed as follows:
nExamine the packaging for transport
damage.
nTake the pump carefully out of the pack-
aging.
nExamine the pump for any visible dam-
age.
nRemove all plugs from the pump ports.
nMake sure that accessories, such as
seals and ushing lines, are free of
damage.
Consider the indicated weight
before attempting to lift the
pump. Use only lifting gear of
appropriate capacity.
Do not step or stand under sus-
pended loads.
Fasten the lifting gear so that the pump (or
pump with drive unit) can be safely lifted
(see example).

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 rotates inside the separating
part 3, which is tightly bolted to the housing.
This separates the suction area 4 from the
inside of the pump 5.
The abutment 2 (Fig. 3) is an elastomer part
and is installed in the pump section where
the hose is squeezed to maximum extend.
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 separating part (Pos. 3, Fig. 3) sepa-
rates the suction area from the inside of the
pump and protects the pumping hose. In
case of hose breakage it additionally pro-
tects the rotor (Pos. 1, Fig. 3) against dam-
age caused by abrasive or coarse particle
product. The separating part can be re-
placed by simply unscrewing two screws.
The pump is lled with 1-2 litres of glycerine
or silicone, which works as lubricant, barrier
and coolant.
The vacuum gauge (Fig. 3a), which is con-
nected with the suction room (Pos. 4, Fig. 4)
not only shows the current suction head of
the pump, but also serves as warning ele-
ment in case of possible defects. If the vac-
uum gauge does not indicate any vacuum
during operation, the pump most certainly
needs servicing.
Maintenance can be carried out without any
special tools.

As the rotor rotates further the suction area
becomes bigger. The fast rotation of the ro-
tor generates a permanent vacuum of down
to -1 bar (Fig. 6).

Since the hose chamber Pos. 6 remains
constant, the pressure area Pos. 7 is
decreased by rotation of the rotor, which
results in a volumetric pumping process
(Fig. 7).
2.0 Safety
2.1 General information
Make sure that the pump is installed in com-
pliance with all applicable national safety
regulations.
Always observe all applicable accident
prevention instructions and implementing
regulations.
Transfer of media of Explosion
Group IIA and IIB is only permit-
ted outdoors or in well ventilat-
ed rooms.
The following precautions must be applied
before performing maintenance work. If
the product to be pumped is a hazardous
or noxious substance, the system must be
neutralized and vented.
Danger of burning!
Depending on operating con-
ditions the pump may reach
temperatures too high to touch.
You should therefore switch o
the pump and let it cool down
before touching it.
nDisconnect main drive unit and pump
from the electric power supply (e.g. pull
out the mains plug).
nDepressurize the pump head.
nIt is not permitted to run the pump after
removing the pump cover. When clean-
ing the pump manually make sure that
all necessary precautions have been
applied.
All incorrectly installed, unprofessionally
operated or insuciently serviced machines
and pumps are potential safety hazards.
The non-observance of relevant safety
measures may cause injury to operating
personnel or damage to the pump.
