4.1 Description
The model CPP120-X pneumatic comparison test pump features optimal characteristics
for use in the laboratory, as well as the ruggedness needed for industrial applications.
The CPP120-X requires a regulated supply of clean dry gas to operate. We recommend
using a Nitrogen cylinder as the gas from this is normally dry and clean. Alternatively use
compressed air, filtered and dried to remove oil and moisture which could cause that the
piston cylinder system or the moveable parts of the base unit become sticky.
4.2 Instrument base
The CPP120-X instrument base consists of a solid aluminium base plate mounted on four
adjustable levelling feet, a volume adjuster, control valves, pipework to two stainless steel
pressure connection blocks.
The pipework and above mentioned assemblies are covered by an easy to clean ABS
cover.
The component identification (number in the circle) in each procedure refer to
the following figure.
