2. Safety
The manufacturer does not accept any liability
for damage resulting from disregard of this
documentation.
2.1 Intended use
Only use the pump to handle compatible uids as
recommended by the manufacturer
(g 10.1 Technical specications).
Adhere to the operating limits.
Consult the manufacturer regarding any other use
of the pump.
Pumps delivered without a motor must be tted
with a motor in accordance with the provisions of
EC Machine Directive 2006/42/EC.
Prevention of obvious misuse (examples)
Note the operating limits of the pump with regard to
temperature, pressure, ow rate and motor speed
(g 10.1 Technical specications).
Do not operate the pump while the inlet/outlet valve
is closed.
Only install the pump as recommended in this manual.
For example, the following are not allowed:
– Installing the pump without proper support.
– Installation in the immediate vicinity of extreme hot
or cold sources.
2.2 General safety instructions

out any work.
2.2.1 Product safety
These operating instructions contain fundamental
information which must be complied with during
installation, operation and maintenance. Therefore
this operating manual must be read and
understood both by the installing personnel and
the responsible trained personnel / operators prior
to installation and commissioning, and it must
always be kept easily accessible within the
operating premises of the machine.
Not only must the general safety instructions laid
down in this chapter on “Safety” be complied with,
but also the safety instructions outlined under
specic headings.
Operate the pump only if the pumping unit and all
associated systems are in good functional
condition.
Only use the pumping system as intended, fully
aware of safety and risk factors involved,
and in adherence to the instructions in this manual.
Keep this manual and all other applicable documents
complete, legible and accessible to personnel at all
times.
Refrain from any procedure or action that would pose
a risk to personnel or third parties.
In the event of any safety-relevant faults, shut down the
pump immediately and have the malfunction
corrected by qualied personnel.
The installation of the pump, associated pipe work and
electrical ttings must comply with the requirements
of installation given in this manual and any local
national or regional health and safety regulations.
2.2.2 Obligation of the operating company
Safety-conscious operation
Ensure that the following safety aspects are observed
and monitored:
– Adherence to intended use
– Statutory or other safety and accident-prevention
regulations
– Safety regulations governing the handling of
hazardous substances if applicable
– Applicable standards and guidelines in the country
where the pump is operated
Make personal protective equipment available
pertinent to operation of the pump; as required.
Qualied personnel
Ensure that all personnel tasked with work on the pump
have read and understood this manual and all other
applicable documents, including the safety,
maintenance and repair information, prior to use or
installation of the pump.
Organize responsibilties, areas of competence and
the supervision of personnel.
Have all work carried out by specialist technicians
only.
Ensure that trainee personnel are under the
supervision of specialist technicians, at all times, when
working on the pumping system.
Safety equipment
Provide the following safety equipment and verify its
functionality:
– For hot, cold and moving parts: safety guarding
should be provided by the operating company.
– For potential build up of electrostatic charge:
ensure appropriate grounding if and when
required.

2.3.3 Sharp edges
Pump parts, such as the shims, can be sharp
– Use protective gloves when carrying out any
work on the pump
3. Layout and function
Peristaltic hose pump, Verderex Dura, is simple by
design in its construction and operation. The medium
to be pumped does not come into contact with any
moving parts and is totally contained within a robust,
heavy-duty hose, which consists of an inner layer, two
– six reinforcement layers and an outer layer. A rotor
passes along the length of the hose, compressing it.
This motion forces the contents of the hose directly in
front of the rotor to move forward along the length of
the hose in a ‘positive displacement’, peristaltic
movement. In the wake of the rotor’s compressing
action, the natural elasticity of the polymer reinforced
rubber forces the hose to open and regain its round
prole, creating suction pressure, which recharges the
pump.
3.1 Design details
Verderex Dura is a twin lobe, single rotor,
peristaltic pump with quick-t tapered port ange
design which clamps and seals in one easy movement
to speed hose replacement.

Warranty
The warranty is voided if the customer fails to follow
any and all instructions, warnings and cautions in this
document. Verder has made every effort to illustrate
and describe the product(s) in this document. Such
illustrations and descriptions are, however, for the sole

terms and conditions.
2.2.3 Obligation of personnel
It is imperative that the instructions contained in this
manual are complied with by the operating personnel
at all times.
Pump and associated components:
– Do not lean or step on them or use as climbing
aid
– Do not use them to support boards, ramps
or beams
– Do not use them as a xing point for winches
or supports
– Do not de-ice using gas burners or similar tools
Do not remove the safety guarding for hot, cold or
moving parts during operation.
Reinstall the safety equipment on the pump as
required by regulations after any repair / maintenance
work on the pump.
2.3 Specic hazards
2.3.1 Hazardous pumped liquids
Follow the statutory safety regulations when handling
hazardous pumped liquids (e.g. hot, ammable,
poisonous or potentially harmful).
Use appropriate personal protective equipment when
carrying out any work on the pump.
2.3.2 Lubricants
Ensure that the lubricant and pumped liquid are
compatible with each other. This is a precautionary
measure in case of accidental hose burst whereby
the pumped liquid comes in contact with the
lubricant.
(Refer datasheet for lubricant to ensure
compatibility)
