KCS3 Stepper-Driven Peristaltic Pump
Stable Fluid Transfer with Flexible Tubing and Installation Options
The Kamoer KCS3 is a compact peristaltic pump driven by a 42 mm stepper motor. With a specified flow range of 0.1–300 mL/min, multiple tubing sizes, three- or six-roller configurations, and several installation options, it is designed for precision liquid dispensing and stable fluid transfer in OEM equipment.
The liquid contacts only the tubing, helping isolate the pump mechanism from the medium and simplifying fluid-path maintenance. The KCS3 is suitable for analytical instruments, medical diagnostic equipment, laboratory systems, environmental instruments, printing equipment, washing systems, industrial machinery, and other automated devices.
Key Features
Stepper Motor Drive
The stepper motor supports accurate speed and direction control, allowing the pump to be integrated into equipment requiring adjustable and repeatable fluid transfer.
Optional drivers support RS485, analog control, external triggers, and other automation functions.
Wide Flow Range
The KCS3 provides a specified flow range of 0.1–300 mL/min. Different tubing sizes and rotor configurations allow the pump to cover low-, medium-, and higher-flow applications.
Actual flow depends on:
-
Tubing size and material
-
Motor speed
-
Number of rollers
-
Liquid properties
-
Outlet pressure
-
Operating conditions
Three- and Six-Roller Configurations
Two rotor configurations are available:
This allows equipment manufacturers to balance maximum flow and pulsation according to the application.
Quick-Release Tubing
The quick-release pump head makes tubing installation and replacement convenient, reducing the time required for fluid-path maintenance.
The pump is designed for tubing with a wall thickness of approximately 1.6 mm.
Multiple Tubing Options
The KCS3 supports BPT and silicone tubing:
| Tubing Code |
Internal × External Diameter |
Material |
| 13# |
0.8 × 4.0 mm |
BPT |
| 14# |
1.6 × 4.8 mm |
BPT |
| 19# |
2.4 × 5.6 mm |
BPT |
| 16# |
3.2 × 6.4 mm |
BPT |
| 40# |
4.0 × 7.2 mm |
Silicone |
Because chemical resistance depends primarily on the tubing, compatibility should be confirmed using the actual liquid, concentration, temperature, pressure, and duty cycle.
Flexible Installation
The KCS3 is available with three installation structures:
The pump includes four mounting holes for convenient equipment integration.
Multiple Connector Options
Available fluid connection options include:
Optional straight connectors, tubing-to-rigid-tube connectors, inverted-cone fittings, and anti-floating suction fittings are also available.
Durable Mechanical Structure
The KCS3 uses an aluminum-alloy latch and synchronous disc, a stainless-steel or cold-rolled-steel motor mount, PET rollers, and PP connectors. This structure supports reliable operation in embedded equipment.

The noise value was measured at a distance of 50 cm with an ambient noise level of 35 dB. Service-life figures are reference values stated in the product manual and should be verified against the actual speed, load, pressure, tubing compression, and duty cycle.
Reference Flow at 450 rpm
Reference values measured at 24 V and 1.2 A:
| Tubing |

105 mL/min |
| B16 |
225 mL/min |
155 mL/min |
| S40 |

250 mL/min |
The general product flow range is specified as 0.1–300 mL/min. The 305 mL/min figure is an individual reference measurement for the three-roller S40 configuration.
These flow values were measured using pure water at 20°C, standard atmospheric pressure, and zero outlet pressure. Actual flow may vary with the liquid, outlet pressure, tubing condition, and motor-speed tolerance.
Control Options
The KCS3 can be paired with optional control modules supporting:
-
Internal or external potentiometer speed adjustment
-
MODBUS RTU communication
-
RS485 control
-
0–10 V analog speed control
-
Electric or trigger-based start/stop
-
Clockwise and counterclockwise operation
-
Rotary encoder control
-
Foot-switch control
-
External analog signals
Selection and Operating Notes
Tubing compatibility should be checked before use. Incorrect tubing selection may cause rapid tubing deterioration or liquid leakage.
The recommended operating environment should not exceed 45°C or 70% relative humidity, non-condensing. Excessive loading or unsuitable operating conditions may shorten pump life.
If the pump remains unused for an extended period with the tubing compressed, the tubing may temporarily adhere internally and prevent priming. Removing and gently rolling the tubing can help restore its elasticity.
Real-liquid testing under actual operating conditions is recommended before final model selection.
