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 environ-
ment 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.
NOTICE
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 applica-
tions.
1.1.1 Model versions
The 823 Membrane Pump Unit is available in the following three versions:
2.823.0010 823 Membrane Pump
Unit
2.823.0020 823 Membrane Pump
Unit
with aspiration equip-
ment
2.823.0030 823 Membrane Pump
Unit
with rinsing equipment
Each version includes different accessories according to its use (see chap-
ter 8, page 20).

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 Pro-
cessor (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 sys-
tems 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.
