M1-KPVP Valveless Piston Pump
Precision Dosing for Corrosive Liquids and Organic Solvents
The Kamoer M1-KPVP is a compact, integrated valveless piston pump designed for high-precision dosing and continuous transfer of corrosive liquids and organic solvents. Its fluid-contact components are made of PVDF, PTFE, and zirconia ceramic, providing excellent corrosion and wear resistance for demanding fluid-handling applications.
Driven by a stepper motor, the M1-KPVP supports accurate speed and displacement control. It offers both dispensing and continuous operating modes, making it suitable for applications such as pouch-cell electrolyte filling, chemical reagent dosing, and precision liquid dispensing.
Key Features
Accurate Stepper Motor Control
The stepper motor enables precise speed and displacement control for repeatable liquid dispensing. The pump supports calibration to improve dosing performance under specific operating conditions.
Multiple Displacement Options
Standard pump head displacement options include:
-
100 μL/shot
-
200 μL/shot
-
300 μL/shot
Customized displacement configurations are also available for specific OEM requirements.
Corrosion-Resistant Fluid Path
The fluid-contact components use carefully selected materials:
This material combination makes the pump suitable for transferring many corrosive liquids and organic solvents. Chemical compatibility should be confirmed according to the actual liquid, concentration, temperature, and connecting tubing.
Durable Zirconia Ceramic Pump Assembly
The high-wear-resistance zirconia ceramic assembly provides a pump head service life of more than 10 million cycles under Kamoer laboratory test conditions.
Flexible Control Options
The M1-KPVP can be operated through:
Supported functions include start/stop, direction switching, speed adjustment, calibration, and suck-back.
Compact and Easy to Operate
A 1.8-inch color display and simple three-button interface allow operators to view and adjust pump settings conveniently. Its compact integrated design simplifies installation in laboratory equipment and automated production systems.
Protected Pump Head
The pump head section has an IP66 protection rating, helping protect it against dust and water ingress in demanding operating environments.

Selection and Maintenance Notes
The liquid must be free of particles, as particles may affect dosing performance, shorten pump head life, or damage the ceramic assembly.
For liquids that can crystallize or adhere to internal surfaces, clean the pump promptly after use and ensure that no residue remains on the ceramic components.
Before model selection, please provide the liquid name and concentration, target dose or flow rate, operating pressure, liquid temperature, duty cycle, control method, and chemical compatibility requirements. Real-liquid testing under actual operating conditions is recommended.
