About this chapter
This chapter gives an overview of the Peristaltic Pump P-1 instrument, and a brief de-
scription of its function.
Introduction to Peristaltic Pump
P-1
Peristaltic Pump P-1 is a single channel laboratory pump for use in liquid chromatography
and other applications where accurately controlled liquid flows are required.
Pumping action is provided by a roller cage driven by a stepper motor controlled by a
range selector and a continuously variable potentiometer. The motor speed is almost
independent of temperature (0°C to 40°C) and load thus giving an accurate and repro-
ducible flow rate under all conditions.
An asymmetric shape gives the pump a very low pulsation in the forward direction. The
reverse direction has a pulsation which is more similar to traditional peristaltic pumps.
Maximum flow function and a connector for remote control and pulse counting are
provided.
