Gas sampling and gas conditioning technology 6-1.1.7-ME
for the problems in the analyze technique. The pump is gas-tight and operates without any mainten-
ance.
7 RANGE OF APPLICATION
All sample contacting parts of the diaphragm pump MP47-Z-BPR150 are made of PTFE, PVDF and
Viton or Kalrez. The lifted gas remains analytically pure due to the fact that the pump works absolutely
without any lubricant. A special diaphragm and valve system guaranties a long life time and no main-
tenance is necessary. The pump is available for 230V or 115V.
One problem in the analyze technique, when lifting gases via filters, is that the filters are clogged after
a longer period of time. This causes an increasing differential pressure above the filter and subse-
quently, a higher suction pressure for the pump is necessary. This, however, results in a decrease of
the adjusted pump capacity.
In order to avoid this negative influence, the M&C diaphragm pump MP47-Z-BPR150 is equipped with
a fully adequate bypass admission pressure regulator inside the pump head. Independent from the
changing entry pressure, the bypass admission pressure regulator keeps the pressure at the pump
outlet constant, so that the adjusted pump capacity resulting thereof remains constant as well.
For example, the entry pressure may vary from 0,46 bar abs. to 1,1 bar abs. for a pump capacity of
250Nl/h.
The outlet pressure is adjusted at works to 200mbar overpressure (adjustable up to 300mbar).
• Delivery of gases and vapors with a temperature of - 30 °C to + 80 °C.
• Maximum admissible operating overpressure, final vacuum, pump capacity: see technical data.
• Before using the pump in unknown mediums, check the compatibility of the pump head and valve
materials with the respective medium.
8 AMBIANCE
Please keep the following ambient conditions during operation:

Range of ambient temperature during operation: -10 °C to + 40 °C.

The pumps must be protected against water and dust effects.

During operation, a sufficient supply of cooling air must be provided.
8.1 SAFETY
The pumps MP47-Z-BPR150 are executed according to protection IP20 and do not provide any pro-
tection against touching and foreign bodies.
N O T E !
The diaphragm pumps of the series MP47 must not deliver liquids.
