Introduction
The U.S. Solid peristaltic pump delivers precise, contamination-free fluid transfer, making it ideal for laboratory, medical, pharmaceutical, and industrial applications.
Equipped with a KZ25 pump head, it supports 15#, 24#, 35#, and 36# tubing, with a speed range of 40–600 rpm and a flow rate of 115–6000 mL/min. Three operating modes—Speed, Flow, and Timer—provide flexible control for different applications.
Powered by a brushless motor, the pump offers high efficiency, stable operation, low maintenance, and long service life. Speed can be adjusted manually via the digital knob or through the external control interface.

FAQ
1.What type of peristaltic pump is this? What are its main functions?
This is a speed-variable peristaltic pump featuring three operating modes: Speed, Flow, and Timer. It allows users to adjust the motor speed, operate at a preset flow rate, or set a timed operation. Additional functions include start/stop control, direction reversal, and full-speed operation.
2.Does it have a timing function?
Yes, it has a basic timer. You can set the duration, and the pump will stop automatically when the time runs out. The timer remembers the last set value.
3.Does it support external control?
Yes. Move the switch on the back of the pump to the right to enter external control mode. Please note that the buttons and knobs will remain functional in this mode.

- Supports RS485 communication and four external control signal inputs: 0–5V, 0–10V, 4–20mA, and 0–10KHz. To use these functions, the corresponding optional module is required (DB15 female connector on one end, screw terminal on the other).
- The external control module is not included with the product. If you need one, please contact customer service.
4.Which types of tubing are compatible with this peristaltic pump? Are they included in the package?
Applicable tubing sizes are 15#, 24#, 35# and 36#. The kit includes one piece of each size, with a length of 2 meters per piece. Common-size tubing information is provided below for reference only and does not imply full compatibility with all listed sizes.
5.Does it have an anti-drip setting?
No.
6.Does it support flow calibration?
No.
