Description
Pump P-960 is a single-channel
laboratory pump for use as a
sample pump in ÄKTAdesign
liquid chromatography systems.
Liquid in an external vessel is
drawn into the pump by three
plunger pumps. They are
actuated in a sequential order by
a stepper motor. In combination
with check valves in the
connection part, it results in a
smooth flow from the pump.
The pressure generated by the sample pump is continuously monitored
by the pressure sensor located above the connection part. The signal,
which is proportional to the pump pressure, is monitored by
UNICORN via the UniNet-2 connection.
The connection part is made of PEEK.
6.2
Cable connections
The pump has a connector underneath
(the leftmost) for connection to the
UniNet-2 communication network. This
enables control of the pump from
UNICORN, version 4.12 or higher, via
Pump P-900 or Pump P-920. The
UniNet-2 cable also supplies power to
the pump.
The pump is also equipped with a
connector (the rightmost) for connecting
an air sensor, Air-912N or Air-925N, directly to the pump.
