PARISA Technology digital peristaltic pump,

The PARISA Technology Digital Peristaltic Pump is a variable-speed liquid transfer and dispensing instrument designed for controlled movement of liquids through flexible tubing. The visible control panel features a four-digit digital display, Start/Stop control, speed adjustment buttons marked RPM, a Prime function, and forward/reverse direction indicators.

A peristaltic pump works by rotating rollers that compress flexible tubing in sequence, moving liquid through the tube without requiring the liquid to contact the pump's internal drive mechanism. This design can help reduce cross-contamination and is useful in applications where controlled liquid transfer, dosing, or dispensing is required. PARISA Technology manufactures peristaltic pumps for laboratory and industrial liquid-handling applications.

The unit shown has a front-mounted pump head with a visible rotor assembly and a mechanical adjustment knob. The pump head is the section responsible for compressing the tubing as the rotor turns. The condition of the rollers, tubing channel, retaining mechanism, and adjustment assembly should be inspected before use.

The digital RPM display and up/down buttons allow the operator to adjust the pump's rotational speed. The actual flow rate depends on the selected speed, the tubing's internal diameter and wall thickness, the liquid's characteristics, and the pump-head configuration. Therefore, the RPM setting should not be treated as a direct measurement of flow rate unless the pump has been calibrated for the selected tubing and operating conditions.

The Prime function is intended to help fill the tubing and move liquid through the pump before normal operation. The forward and reverse controls allow the operator to change the direction of rotor rotation, which can be useful when loading tubing, transferring liquids, or clearing residual liquid from a line where the procedure permits.

Peristaltic pumps are used in laboratories, pharmaceutical research, biotechnology, chemical processing, liquid dispensing, and other applications requiring controlled fluid movement. Depending on the selected tubing material and pump configuration, they may be suitable for transferring buffers, culture media, reagents, and other compatible liquids. Tubing compatibility must be checked against the liquid's chemical properties and the intended operating conditions.

The pictured pump has visible dirt, discoloration, and surface wear. Its current operating status cannot be established from the photograph. Before sale or laboratory use, the pump should be checked for motor operation, speed adjustment, forward/reverse function, prime operation, pump-head condition, and tubing compatibility.

PARISA Technology offers multiple peristaltic pump models with different flow rates and rotational speeds. The exact model of this pictured unit is not legible, so specifications from another model should not be assigned to it without verification.

This unit can be listed as a PARISA Technology digital peristaltic pump once the model number and operational condition have been confirmed. Providing the maximum RPM, calibrated flow range, compatible tubing dimensions, power requirements, and included accessories will help buyers assess its suitability for their liquid-handling workflows.
