Kamoer KLP02-E KC 12V Single Head Brushed Motor Diaphragm Pump

The Kamoer KLP02-E KC is a precision 12V DC diaphragm pump featuring a brushed motor design with single head peristaltic pumping mechanism, engineered for accurate fluid transfer in laboratory, medical, and industrial automation applications. Professional researchers, water treatment technicians, and OEM manufacturers rely on this pump for consistent dosing of chemicals, pharmaceuticals, and aqueous solutions with flow rates up to 2 liters per minute. This pump solves critical challenges in micro-dosing applications where traditional centrifugal pumps fail, offering precise volumetric control, dry-run capability, and compact form factor for space-constrained installations.

Product Overview

The Kamoer KLP02-E KC operates on the positive displacement principle using a brushed DC motor to drive a single diaphragm head that creates reciprocating suction and discharge strokes. This peristaltic design eliminates internal seals and valves that typically require maintenance, making it ideal for corrosive or abrasive fluid handling. The 12V DC motor draws minimal current while delivering consistent pressure up to 0.8 MPa, suitable for both gravity-fed and pressurized delivery systems. The brushed motor architecture provides excellent torque characteristics at low speeds, enabling smooth operation and extended motor life in continuous duty applications.

What distinguishes the KLP02-E KC is its single-head configuration that reduces vibration and noise compared to multi-head designs, while the brushed motor offers superior reliability in industrial environments without requiring complex electronic commutation. The pump features integrated check valves that prevent backflow, allowing it to function effectively in both horizontal and vertical orientations. Its compact 85x65x95mm footprint makes it suitable for portable equipment, benchtop analyzers, and embedded system integration where space optimization is critical.

Key Specifications

Applications and Use Cases

• Laboratory Fluid Dispensing in analytical instruments, spectrophotometers, and automated sample preparation systems requiring precise micro-dosing of reagents and calibration solutions
• Medical Device Integration in infusion pumps, dialysis machines, and point-of-care diagnostic equipment where reliable peristaltic action ensures sterile fluid transfer without contamination
• Water Treatment and Chemical Dosing for pH adjustment, chlorination, and coagulant injection in municipal and industrial water purification systems with 0.8 MPa pressure capability
• Aquaculture and Hydroponics Nutrient Delivery in automated feeding systems and nutrient solution circulation where low-noise operation prevents stress to aquatic organisms
• Automotive and Industrial Testing in fuel injection testing rigs and hydraulic fluid circulation systems requiring consistent volumetric flow at low voltage

How to Use

Begin setup by connecting the 12V DC power supply to the motor terminals, ensuring correct polarity to prevent motor damage. Attach inlet and outlet tubing to the 6mm barbed connectors using hose clamps for secure connections. For priming, fill the inlet line with fluid or allow gravity feed to establish initial flow. The pump operates immediately upon power application without requiring air bleeding or complex startup procedures. Position the pump at or below the fluid source level for optimal suction performance, or use inlet pressure up to 0.8 MPa for pressurized source applications.

During operation, monitor outlet pressure using an optional pressure gauge if operating near maximum rated pressure of 0.8 MPa. The brushed motor will draw approximately 1-2 amps at full load, so ensure your power supply provides adequate current capacity. For extended operation, maintain ambient temperature between 5-40 degrees Celsius to preserve motor winding integrity. The pump can operate continuously or intermittently depending on application requirements. If the pump will be idle for extended periods, flush the lines with clean water to prevent fluid crystallization or bacterial growth within the diaphragm chamber.
