3.1 114DV pumpheads
The 114DV pumphead has four rollers and accepts 1.6mm wall thickness tubing only. New tubing can be
easily loaded into the flip top design. The top closes with a “clamp and stretch” action to locate the tube in
thecorrectposition and with thecorrecttension.
114DV pumping conditions: pressure and viscosity
•
All pressure values in this operating instruction, from which performance life figures have been
calculated, relate to root mean square (RMS) pressure, giving a more relevant pressure value than
figures quoted in terms of peak pressure. The RMS pressure is similar to the value you would read
on a damped analogue gauge.
•
Ensure that on longer tube runs at least one metre of smooth bore, flexible tubing is connected to
the inlet and discharge port of the pumphead to help to minimise impulse losses and pulsation in
thepipeline. Thisisespecially importantwith viscousfluidsand when connecting to rigid pipework.
Safety information
There are moving parts inside the pumphead. Before opening the pumphead track, ensure
that the following safety directions are followed.
•
Ensure thatthepump isisolated from themainspower.
•
Ensure thatthere isno pressure in thepipeline.
•
If a tube failure hasoccurred, ensure that any fluid in the pumphead hasbeen allowed to drain to a
suitable vessel, container or drain.
•
Protective clothing and eyeprotection mustbeworn if hazardousfluidsarepumped.
Always isolate the pump from the mains power supply before opening the
guard or performing any positioning, removal or maintenance activity.
