6 INTRODUCTION
The electrically heated diaphragm pump MP26-H1 is suitable for corrosive hot wet gases. It is con-
structed especially for gas transportation in hot wet gas analysis systems .
7 DESCRIPTION
All sample wetted parts of the pump MP26-H1 are made of PTFE. This makes the pump suitable for
hot wet applications with corrosive gases.
The pump works absolutely lubricant free. This means that the sample remains analytically un-
changed.
Due to a special diaphragm and valve system the pump operates maintenance-free.
The pump head is heated up by an aluminium heater body. It includes the heater cartridges (two each)
and the capillary sensor of the thermostat. The pump head has a metal cover with thermal insulation.
The set-temperature of 0°C to 180°C can be adjusted at the thermostat, located in the terminal box
beside the pump head. The thermostat has an excess temperature limiter which permanently switches
off the heating if the set temperature is exceeded by +30°C. I this case the heater must be reset by
hand. The RESET button is located at the upper right side of the thermostat.
The thermostat has an low-temperature alarm which activates a contact if the temperature decreases
30°C under the set temperature. This status alarm is located on the terminal strip as a potential-free
switch over contact.
The motor is protected by a motor protection switch, which is installed in the terminal box as well. The
motor can be switched on and off by pressing the button „On/Off‟ at the side of the terminal box. Ex-
ternal switching of the motor is also possible with a potential free contact.
The MP26-H1 is available in 230V or 115V.
The standard MP26-H1 is designed for applications at a maximum gas flow of 10l/min.

Maximum temperature for medium during operating: -20 ... +200°C.

The pump must be protected from the effects of dust and water.

Before use please check the compatibility of the material.
