Introduction
The Dynamax RP-1 Peristaltic Pump is specifically designed for fluid
transfer. The rotating head has ten stainless-steel rollers. As the head
rotates, five of the rollers press the tubing up against the compression
arm, producing flow by peristaltic action. Five rollers constantly in
contact with the tubing ensures low pulsation, smooth flow, and high
pressure. Model RP-1 is ideal for critical liquid chromatography, gra-
dient generation, and flow analyzer applications.
The RP-1 incorporates a unique cam design: the adjustment screw
does not press the compression arm directly. Instead, turning the
adjustment screw in the RP-1 moves a cam which applies gradual
force to the compression arm. This results in more precise flow con-
trol and reduced tubing wear.
RP-1 is powered by a high torque stepper motor, controlled by a
microprocessor with unique feedback circuitry for good speed stabil-
ity, even at very low flow rates. Speed stability is maintained between
0� 40�C and against back-pressures of up to 5 bars. Pump speed is
shown in revolutions per minute (rpm) on a liquid crystal display (LCD)
on the pump front panel. Pump speed and direction of rotation are
controlled by a membrane keypad next to the display.
Several pump heads are available: a single-channel model and three
multi-channel versions: 2-, 4-, and 8-channel. Individual tubing com-
pression settings on the multi-channel pump heads allow different
diameter tubing to be used for each channel. Independent compres-
sion settings for each channel ensure optimum flow rate and long tub-
ing life.

Description
9920-179 rev D 1/20/04 11:42 AM Page 5 Fixed collars bonded to the tubing allow easy tube installation at the
proper tension, which in turn ensures that the tubing diameter is opti-
mized and not altered from day to day. The precise and accurate motor
speed setting, correct tubing tension, and reproducible tubing diameter
all contribute to ensuring reproducible flow rates.

The Dynamax Model RP-1 Peristaltic Pump was shipped in excellent
working condition. Inspect the pump on receipt for possible shipping
damage. In case of damage, file a claim immediately with the shipping
carrier damage sustained in transit is the responsibility of the carrier.
Save the shipping container and packing materials until any damage
claim is resolved and the pump is functioning properly. The container
and packing materials also afford excellent protection during future stor-
age or transportation.

9920-179 rev D 1/20/04 11:42 AM Page 6 2: Controls and Indicators
LCD:
The 3-digit, 2-symbol liquid crystal display shows motor
speed in rpm. When the pump is running, a plus or minus sign is also
displayed to indicate clockwise (+) or counterclockwise () rotation of
the pump head.
PRIME key:
High-speed override, for priming the tubing lines.
Pressing this key when the pump is running speeds the pump to its
maximum rate of 48 rpm. (Pressing the key has no effect when the
pump is not running.) The pump remains at the high flow rate until the
PRIME key is pressed again, or until either of the two START keys is
pressed. Then the pump reverts to its previous speed.
MINUS key: Decreases motor speed. Pressing and holding this key
while the pump is running decreases the pumping speed continually
as long as the key is held. Pressing and holding the key while the
pump is not running sets the speed at which the pump will operate
when it starts.
PLUS key:
Increases motor speed; use is similar to MINUS key.

9920-179 rev D 1/20/04 11:42 AM Page 7 START Clockwise key:
Pressing this key when the pump is stopped
starts the roller barrel rotating clockwise at the speed displayed on the
LCD. Pressing it while the pump head is at maximum speed (after the
PRIME key has been pressed) causes the pump to revert to its previ-
ous speed. Pressing the key while the pump is running counterclock-
wise stops the roller barrel and immediately starts it rotating clockwise
at the same speed.
START Counterclockwise key:
Used in a similar way to the START
Clockwise Key.
STOP key:
Stops the pump and stores the value displayed on the
LCD. This value is used when the pump is started with either of the
START keys.
Power Line Module:
Power is supplied to the RP-1 pump via a
power line module containing:
1.
Power On/Off Switch Two-position rocker switch that supplies
AC power. I is ON, O is OFF.
2.
Power Cord Receptacle Grounded three-pin receptacle.
Accepts the power cord supplied in the accessory kit.
3.
Fuse/Line Voltage Selector Two-position 110V/220V line volt-
age selector containing two fuses.
