8.1 Theory of Operation
The pump motor consists of an electric motor and a pulley assembly controlled by a microprocessor and circuit board. Driven by ac power, the motor produces a torque which drives the pulley assembly. The pulley assembly reduces the motor output speed and drives the pump. All of the pump motor’s functions are regulated by the microprocessor and circuit board. You enter information to the motor via a membrane keypad.
8.2 Design Considerations
Customers commonly desire a pump motor that they can calibrate to obtain accurate flow rates with a wide variety of tubing materials, sizes, and durometers. They also want the ability to pump fluid from more than one source container at the same time. In addition, they may need the freedom to pump fluid in opposing directions at the same time. Customers also desire a variety of ways by which to pump their fluid. Above all, they want to carry out all these processes with a
8.3 Design Solution
The peristaltic pump motor satisfies today’s diverse customer needs. Its sophisticated software allows customers to calibrate the motor for use with a wide range of tubing materials, sizes, and durometers, to obtain accurate flow rates. It can accept two stacked pumps with fluid flowing in the same direction in both pumps, or one pump on each side with fluid flowing in opposite direction in the pumps. The pump motor is equipped with user friendly software and four modes of pumping: RPM, FLOW RATE, TIME, and TOTAL VOLUME.
8.4 Maintenance
There is no need for any preventive maintenance work. There are no user serviceable parts inside the peristaltic pump motor. All bearings are
The fuse may be replaced from the outside of the unit. Refer to figure 1.2 for the location. Simply press down on the plastic fuse holder door, and slide it open. The fuse used by the pump motor is closest to the case. The spare fuse is located under the word “Press”. Make sure Power is off and the line cord unplugged when changing the fuse.
