Safety Cautions
Danger: Please use correct AC power voltage source shown on
the sticker attached on the equipment to avoid any damage.
Please do not open the case. High voltages exist and are
accessible. Use extreme caution when servicing internal components.
For maintenance, please contact the manufacturer or distributor directly.
Danger: Turn drive off before removing or installing tubing. Fingers or loose
clothing could get caught in drive mechanism.
Warning: Tubing breakage may result in fluid being sprayed from
pump. Use appropriate measures to protect operator and
equipment.
Warning: Remove power from pump before attempting any maintenance or
any cleaning operation is started.
Warning: Remove power from pump before connecting or disconnecting
the external control device or communication interface.
Warning: Pump is provided with a grounded plug, it must be well-grounded
at all times.
Warning: This product is not designed for, nor intended for use in patient
connected applications; including, but not limited to, medical and dental use.

1 Introduction
PP-D-720 basic variable-speed peristaltic pump provides not only the
basic functions such as reversible direction, start/stop and adjustable
speed, but also Time Dispense Mode and Anti-Drip function. With
MODBUS RS485 interface, pump is easy to communicate with external
device, such as PC, HMI or PLC. This pump series includes:
•flowrate0.00011-720 mL/min, speed0.1-150 rpm
2 Functions and Features
Advantage of peristaltic pump: Peristaltic pump can handle extremely
viscous fluids, abrasive slurries and corrosive fluids. There is no seals in
contact with the medium pumped and no valves to clog. The inner surfaces
are smooth and easy to clean; fluid contacts only the tubing or tube material.
Suction lift and priming can be up to 8m water column at sea level. It can
handle the most shear sensitive of fluids like latex or firefighting foam with
low shearing. It is capable of running dry and pumping fluids with high
quantities of entrained air, such as black liquor soap. The high volumetric
efficiency allows operation in metering or dosing applications where high
accuracy is required. Tubing and tube materials are available for food and
pharmaceutical use.
•LCD displays rotating speed and working mode.
•Membrane keypad.
•Reversible direction, start/stop control and adjustable speed.
•Time dispense mode: automatically dispense bysetting the duration
for each dose, lag time between doses and number of cycles.
1

•0.5% high precision rotating speed control with 0.1 rpm speed
resolution when speed is between 0-100 rpm, 1 rpm speed
resolution when speed is between 100-600 rpm.
•External logic level signal can control start/stop, direction and
dispense functions; external analog signal can adjust the rotating
speed. Signal is optically isolated.
•With RS485 MODBUS interface, easy to communicate with external
device.
•Internal double-layer isolation structure; circuit board with conformal
coating makes the pump dust-proof and moisture proof.
•Anti-electromagnetic interference feature, wide input voltage range
for complex power environment.
•Stainless steel enclosure, easy to clean, resistant to the corrosion of
the acid, alkali, sodium and organic solvents.
