1 Introduction
1.1 Instrument description
The 823 Membrane Pump Unit is a versatile membrane pump. It was
designed specifically for the production operation and laboratory environment and enables a wide range of applications. Particularly when used in
a Metrohm automation system with Sample Processor and various analysis
instruments, it is of indisputable service in processing large sample series
in the complete titration area and in various measuring applications or
other analytical tasks.
The 823 Membrane Pump Unit uses the membrane pump principle (see
Chapter 2.1, page 6) and is suitable for pumping all types of liquid
media.
Note
1 Introduction
The 823 Membrane Pump Unit is not suitable for pumping liquids with
solids content.
The flow rate of at least 450 mL/min opens up a wide range of applications.
1.1.1 Model versions
The 823 Membrane Pump Unit is available in the following three versions:
2.823.0010
2.823.0020 823 Membrane Pump
2.823.0030 823 Membrane Pump
Each version includes different accessories according to its use (see Chap-
ter 9, page 23).

1.2 About the documentation
1.1.2 Connectors
The 823 Membrane Pump Unit needs 16 - 24 V DC voltage.
Power is supplied to the pump via the direct connection to a Sample Processor (e.g. 814 or 815) or to the 731 Relay Box (connection via adapter
cable 6.2160.010).
1.1.3 Intended use
The 823 Membrane Pump Unit is designed for usage in automated systems in analytical laboratories.
This instrument is suitable for pumping chemicals and flammable samples.
Use of the 823 Membrane Pump Unit therefore requires the user to have
basic knowledge and experience in handling toxic and caustic substances.
Knowledge with respect to the application of the fire prevention measures
prescribed for laboratories is also mandatory.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Warning
Never open the housing of the instrument. The instrument could be
damaged by this. There is also a risk of serious injury if live components
are touched.
There are no parts inside the housing which can be serviced or replaced
by the user.
Mains voltage
Warning
An incorrect mains voltage can damage the instrument.
Only operate this instrument with a mains voltage specified for it (see
rear panel of the instrument).
Protection against electrostatic charges
Warning
Electronic components are sensitive to electrostatic charges and can be
destroyed by discharges.
Do not fail to pull the mains cable out of the mains connection socket
before you set up or disconnect electrical plug connections at the rear
of the instrument.
1.3.3 Tubing and capillary connections
Caution
Leaks in tubing and capillary connections are a safety risk. Tighten all
connections well by hand. Avoid applying excessive force to tubing
connections. Damaged tubing ends lead to leakage. Appropriate tools
can be used to loosen connections.
Check the connections regularly for leakage. If the instrument is used
mainly in unattended operation, then weekly inspections are mandatory.
