touched without following a safety instruction
Explosion
This symbol indicates that there is a risk of explosion if the
pump is misused in a specific manner.
Potential hazard
This symbol identifies that an appropriate safety
instruction should be followed or a potential
hazard exists
3.2.1 Instructions for renewing safety symbols
If the safety labels on the product become accidently damaged, contact your local Watson-
Marlow representative for information on obtaining replacements.

WARNING
The WARNING signal word indicates a hazard. Risk of serious injury or death exists if the
hazard is not avoided. Equipment or property damage may also occur.
A safety symbol
indicates a hazard with
personal injury risk.
Hazard information—Information to explain:
•Hazard type or nature of hazard
•What could happen
•How to avoid hazard
CAUTION
The CAUTION signal word indicates a hazard. Risk of minor or moderate injury exists if the
hazard is not avoided. Equipment or property damage may also occur.
A safety symbol

3.4 Responsibility
A responsible person must use these instructions to:
•Ensure the product will be used within the scope of :
oIntended Use (see section 4.3)
oPumping of flammable liquids (see Section 3.5)
•Prior to a task, such as installation, operation or maintenance
oDo a risk assessment.
oDetermine suitable personal protective equipment (PPE) that must be worn.
Consider the following minimum PPE
Safety glasses
Safety boots
Gloves
•Train an operator to carry out a such as operating the product, cleaning or
maintenance, as required by the users organisation
•Approve water as a cleaning agent for use if required (see section 25)
The product must only be used by persons who have read and understood these instructions
prior to a relevant task.
3.5 Pumping of flammable liquids
The pump is prohibited from installation or operation in explosive atmospheres. If the pump is
to be used for the pumping of flammable liquids, a responsible person must carry out a risk
assessment to ensure an explosive atmosphere could not occur by any activity involving:
installation, operation, maintenance or decommissioning of the product.
The risk assessment should consider all risks, including:
•Leaks or spillage of the flammable liquid during:
oFirst time pumphead installation procedure
oInstallation of all components of the fluid path
oMaintenance replacement of the pumphead
oRemoval of the fluid path, or other decommissioning activity.
•Operating the pump to the point of pumphead tubing failure, resulting in:
oChemical incompatibility with pump materials of construction becoming
exposed to the flammable liquid
oFlow of flammable liquid through the pumphead safety overflow, into the
process safety overflow system
•Ignition and spread of fire due to a leak, spillage or other escape of the flammable
liquid into the process area.
The above list is not exhaustive. Its purpose is to provide additional guidance which a person
unfamiliar with the product, may not otherwise consider.

4Product overview
This section provides a product and specification overview.
4.1 Product introduction
The Qdos®range of peristaltic chemical metering and dosing pumps cut costs through higher
precision metering, with an accuracy of ±1 % and repeatability of ±0.5 % in dosing.
Qdos H‑FLO pump delivers the same outstanding accuracy and reliability as other Qdos pumps
but for higher flow rates, with a high chemical compatibility through a range of pumpheads.
The unique ReNu®pumphead achieves cost savings through minimal maintenance downtime.
ReNu technology is a tool‑free pumphead that fully contains fluid, which keeps your production
area clean and free from contamination risk. The patented design enables accurate and
repeatable flow for fluids of a wide range of viscosities.
4.2 General description
A Watson-Marlow qdos pump provides a flowrate of fluid through a fluid path, by the principle
of positive displacement from the pumphead. A general illustration is provided below:

4.3 Intended use
All model variants of the qdos range of pumps are designed for controlled fluid movement, in
ordinary safe locations, except those fluids or applications listed below:
Prohibited use:
•Environments that require explosion proof certification.
•With fluids not chemically compatible 1
•Installations, environmental or operating conditions which are beyond the
specifications provided in these instructions.
•Applications with are directly life sustaining
•Applications within a Nuclear Island
NOTE 1A procedure for checking chemical compatibility is provided in
section 28.
