Speed-Variable Peristaltic Pump

As the name suggests, the core function of this type of peristaltic pump is speed regulation. By changing the rotation speed of the pump head, it indirectly controls the liquid delivery speed. This is the most basic and common type of peristaltic pump, offering an affordable price and suitability for most simple liquid transfer applications.

This type is easy to operate, typically featuring an LED display and controlled via a knob or buttons (with external control support). Its functions include speed adjustment (core function), start/stop, direction reversal, and full-speed operation. Some models also support simple timing functions. It enables continuous liquid transfer but does not allow for precise control of flow rate or total volume. In practical terms, you can adjust it to "fast transfer" or "slow transfer," but you cannot precisely set it to "10 mL per minute" or "50 mL in total."

It is ideal for applications that do not require high flow rate accuracy or precise volume control, only continuous liquid transfer. Examples include simple liquid transfer in laboratories, water changes or medication dosing in aquariums, and liquid supply for small equipment.
