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).

1.2 About the documentation ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭

2￭￭￭￭￭￭￭￭

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.
