2.1. Proper use
The pumps are exclusively intended for transferring liquids and
gases.
Owner's responsibility
Only install and operate the pumps under the operating parameters
and conditions described in Chapter 4, Technical data.
The pump may be operated only when fully assembled.
Before using a medium, check whether the medium can be trans-
ferred danger-free in the specific application case.
Before using a medium, check the compatibility of the materials of
the pump head, diaphragm and valves with the medium
The temperature of the media must lie within the allowed limits
stated in chapter 4.
The media should not contain particles as these can prevent the
pump from working correctly. If this can not be guaranteed a filter
(approx. 50 µm) must be used in front of the pump.
The .51 versions of our diaphragm liquid pump range have been
certified by NSF according to the standard NSF/ANSI 169 and can
therefore be used, without any limitations, with foodstuffs.
All materials used for the wetted parts have been through a series
of toxilogical tests. In order to ensure that the food grade quality is
maintained NSF will carry out a yearly audit checking all of the
production processes.
Only the pumps marked with ".51" have been certified by NSF and
contain materials which have a FDA certificate of conformity.
