Why Laboratory Diaphragm Pumping Stations are
Needed
2
In this new age of scientific instrumentation and
analysers, the need for fluidics management at an
increasingly accurate rate has eclipsed the
standardized pumping methods used in the past.
3
High-capacity diaphragm pumping stations in the
analytical laboratory are needed for the
efficient operation of many instruments and
analyser, as they depend more and more on
mechanical methods for fluid and gas movements
throughout the systems.
4
Different pumping methods exist, and each
presents its own set of problems encountered by
laboratory personnel. Finding a good match for
the needs of your laboratory does not have to
seem so daunting, as there are so many systems
from which to choose.
5
Finding the pumping system for the analysers and
other instrumentation of the laboratory can be
just a matter of how you operate fluidics or
liquid handling, or what type of analysis is
predominant in the laboratory.
6
One of the best methods for fluid management is
the diaphragm pump. The diaphragm pump is a
deceptively simple design. A diaphragm, or
membrane, is positioned in a pumping chamber,
usually form-fitted to achieve efficient gas or
fluid movement.
7
The membrane can be made of a thermoplastic,
rubber, such as latex, or a PTFE impregnated
plastic. The flexibility is not as important as
the materials ability to withstand against high
temperatures, caustic or acidic chemicals, or
acidic vapors.
8
The diaphragm must be able to run indefinitely
without concern of overheating or general wear
over short periods. The valve system must also
follow certain guidelines for safety and flow
control.
9
The valves must be made of materials that can
also withstand possible hazardous substances, and
not lose their functionality in the exposure to
excessive heat or cold. The valve timing must be
efficient and cause a steady flow of air, fluid,
or gas without interruption or surges.
10
Some diaphragm pumps are used for the negative
pressure, as in vacuum systems used in chemistry
or haematology analysers. Reservoirs are used to
maintain a constant vacuum after the pump has
reached the required pressure, so the pump is
only activated at times when the negative
pressure reaches undesirable levels.
11
The diaphragm pump must withstand on-and-off
operation at different times, and the motor must
be a quick-response electric with auto-shutdown
if overheating is reached. Diaphragm pumps come
in two styles Single head and double head. The
single head can have different capacities,
ranging up to 100 InHg, or 7.0 Bars.
12
This is excellent for the operation of several
instruments that require positive pressure in
their reservoirs. As far as vacuum, a capability
of 1000 Mbars should be available with an
excellent diaphragm pumping system.
13
A dual-head diaphragm pump can provide even more
pressure and ultimate vacuum to handle just about
any need. These larger, high-powered units have
two diaphragms functioning in tandem, so that the
flow rate through tubes is constant and
controlled.
14
With gauges and relief valves, there can be no
doubt about the performance of these versatile
and precision pumping systems. Diaphragm pumps
are the systems of choice for many research and
medical laboratories around the world.
