PINMOTOR N20 Mini Peristaltic Pump 3V-6V DC for Smart Cleaning Devices
Customized Service
To provide customers with quality products and satisfactory service
Key Features
-
No Fluid Contamination: Liquid touches only the flexible silicone tube, keeping both the fluid and pump motor safe from corrosion.
-
Self-Priming & Anti-Siphon: Offers up to 1.5 meters of self-priming height. When turned off, rollers pinch the tube tight to prevent leaks or backflow.
-
N20 Gear Motor Drive: Runs smoothly on low power (3V to 6V DC) with consistent output torque.
-
Compact Design: Small footprint makes it easy to integrate into slim devices like handheld steamers and window-cleaning robots.

Specification Engineering Drawing
Is This Pump Suitable for Your Device?
This pump is generally suitable when:
● The device uses a low-voltage DC power supply
● The required liquid delivery is small
● Installation space is limited
● The pump runs intermittently or under a tested duty cycle
● The liquid is compatible with the selected tube
● The suction and outlet conditions remain within the tested range
Another pump type may be more suitable when:
● Higher flow is required
● The system has high outlet resistance
● The liquid contains particles
● The pump must run continuously for long periods
● The application requires verified dosing accuracy
● The liquid temperature exceeds the tube limit
Typical Applications
Peristaltic Pump for Steam Iron
In a steam iron, the pump can transfer water from the reservoir to the heating or steam-generation section.
The pump should be installed away from direct heat. Engineers should check the water demand of the steam chamber, internal temperature and available mounting space before confirming the final version.
Mini Pump for Steam Comb
Portable steam combs and garment-care devices often require short, intermittent water delivery.
The compact motor structure makes the pump suitable for handheld products, but the final assembly should still be checked for vibration, noise and heat transfer from nearby heating parts.
Mini Liquid Pump for Window Cleaner
In an electric window cleaner, the pump can supply water or cleaning liquid to the wiping head or spray channel.
When the device uses detergent instead of clean water, the liquid formulation and tube compatibility must be reviewed before testing.
Other Compact Equipment
The pump may also be evaluated for beauty equipment, small dispensing devices and other low-voltage liquid systems.
For medical or regulated products, the equipment manufacturer must complete separate material, performance and compliance validation.
Engineering Integration and Performance Considerations
Installation Guidelines
Mount the pump on a stable bracket without applying external force to the motor or pump head. Keep the suction tube short and avoid sharp bends that may restrict liquid flow.
Do not install the pump close to boilers, heating plates or steam chambers. Excessive heat may affect the motor and flexible tube.
Check noise after installation in the final housing, as brackets, tubing and plastic covers may increase vibration.
Liquid Compatibility
Tube material must be selected according to the liquid composition, concentration and temperature.
For detergents, alcohol-based liquids, cosmetic fluids or disinfectants, provide the operating and storage conditions before sample selection. Performance tested with water may differ when handling viscous or chemically active liquids.
Flow and Dosing Performance
Actual liquid delivery depends on voltage, tube dimensions, suction height, outlet resistance and liquid properties.
For applications requiring a fixed volume, define the acceptable tolerance and verify the pump in the complete liquid circuit. Additional testing is required when dosing repeatability is a key requirement.
Operating Life
Pump life depends on the operating load, liquid temperature, tube material, chemical exposure and start-stop frequency.
For projects with a defined service-life target, provide the daily operating time, cycle duration and total expected cycles before sample approval.
Frequently Asked Questions
Q1: Why use an N20 peristaltic pump over a diaphragm pump in a steam iron?
Peristaltic pumps keep liquid completely inside the tube, preventing clog issues caused by scale or mineral buildup. They also act as an auto-shutoff valve when stopped, stopping unwanted water drips.
Q2: How do you adjust the flow rate?
Flow rate changes linearly with motor speed. You can adjust it by changing the voltage (between 3V and 6V) or using a PWM signal to regulate speed.
Q3: Is the pump tubing durable, and how do you replace it?
PINMOTOR uses fatigue-resistant food-grade silicone tubing rated for over 500 hours. The quick-release pump head makes replacing worn tubes fast and low-cost.
Q4: Can this pump handle chemical cleaners or viscous liquids?
Yes, it works well with mild cleaning solutions. For harsh chemicals or solvent-based fluids, PINMOTOR offers chemical-resistant Pharmed BPT or Viton tubing options.
Q5: What is the difference between running at 3V versus 6V?
At 3V, the pump runs quieter with lower flow, ideal for battery-operated devices. At 6V, it reaches maximum motor speed and peak flow performance.
Q6: Does PINMOTOR offer custom OEM/ODM solutions?
Yes, PINMOTOR is a direct manufacturer offering custom motor speeds, shaft dimensions, and tube materials. Samples ship quickly, and the standard MOQ for volume orders is 500 units.
Send us your device application, supply voltage, liquid information, required delivery volume and installation drawing. Our engineering team will review the operating conditions and recommend a sample configuration for testing.
1、Can the flow be adjusted?
The delivery rate may change with voltage and system resistance. The available adjustment range should be confirmed through sample testing.
2、Can the pump transfer cleaning detergent?
It depends on the liquid composition and tube material. Please provide the detergent formula, concentration and temperature for evaluation.
3、Can the pump operate continuously?
The specification includes a continuous-running test, but actual life depends on load, temperature and liquid conditions. Continuous-duty applications require separate verification.
4、Is this pump suitable for accurate dosing?
The current datasheet does not provide dosing accuracy or repeatability. Projects with strict volume control need additional testing.
5、Why does the actual flow differ after installation?
Tube length, suction height, outlet restriction and liquid viscosity can all affect the delivered volume.
6、What information is needed for sample selection?
Please provide the application, voltage, required liquid volume, liquid type, temperature, operating cycle and installation space.
7、Can the wire and connection direction be customized?
Project-specific electrical and mechanical changes can be reviewed according to the drawing and estimated quantity.
8、Is the pump suitable for medical equipment?
Medical use requires separate material, performance and regulatory validation. The standard product specification alone cannot confirm suitability.
