1 Introduction
Intended use
Peristaltic Pump P-1, (Code No. 18-1110-91), is a single channel laboratory pump for
use in liquid chromatography and other applications where accurately controlled liquid
flows are required.
Functional description
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 (0–40 °C) and load thus giving an accurate and reprodu-
cible 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.

RUN/STOP Switch
Starts and stops the pump. Can be overridden by the remote control.
Flow LED
Indicates that the pump is turned on. The pump will now run if not overridden by the
remote control.
Flow Switch
A switch to reverse the flow.
Note: Because of the asymmetric design of the pressure plate, the forward direc-
tion (unbroken arrow on the switch) shows less pulsation than the reverse
direction (broken arrow).

Flow rate switch
A range selector for the flow rate. The switch gives a ten-fold variation of the flow rate.
Pressing the switch to the spring loaded bottom position gives maximum flow rate
independent of the potentiometer setting.
Flow rate potentiometer
A continuously variable potentiometer for the control of the flow rate. Gives a linear
response in the range from 1 to 10.

Figure 2.2: Flow rate guide
A guide showing the relationship between the flow rate and the setting for different
tube diameters is delivered with the equipment. One side of the flow rate guide is adhe-
sive and should be used to stick the guide onto the clear plastic lid.

Mains voltage selector
The socket for mains inlet contains a rotary switch for selection of the appropriate
voltage. The voltages are 100, 120, 230 and 240 V.
Note: Use 230 V setting for 220 V~ mains.
Fuse
Protects the electronics from damage in case of short circuiting. The fuse is located in
the same place as the mains voltage selector. See Fig. 3.1, on page 15.
Remote control
15 pin connector of D-type. The numbers referred to are imprinted on the connector.
