Walfront DC 12V High Peristaltic Pump Silicone Tube 400ml/min

Description

Product Overview

The Walfront DC 12V High Peristaltic Pump is engineered for precision dosing in demanding laboratory and industrial environments. Powered by a reliable 12‑volt DC motor, the pump delivers a maximum flow rate of 400 ml per minute, allowing rapid yet controlled transfer of liquids. Its core components include a transparent silicone tube with an inner diameter of 6.4 mm and outer diameter of 9.6 mm, providing clear visual monitoring of fluid movement. The pump housing combines durable iron and high‑impact PC (polycarbonate) to protect internal mechanisms while keeping the overall weight low at just 0.27 kg (9.5 oz). Ball bearings integrated into the wheel frame reduce friction, resulting in quiet operation and extended service life. The design follows a diaphragm style, which minimizes pulsation and ensures smooth, continuous flow even with viscous solutions.

Usage

This peristaltic pump is versatile across a wide range of applications. In biochemical analysis labs, it can accurately dispense reagents for titration, chromatography, and enzyme assays. Pharmaceutical manufacturing benefits from its ability to handle sterile fluids without cross‑contamination, thanks to the disposable silicone tubing. Biotechnology research often requires gentle handling of cell cultures and media, which this pump provides through its low‑shear action. The pump also excels in water treatment plants for dosing chemicals such as coagulants, disinfectants, and pH adjusters. Its compact footprint (3.94 × 3.94 × 1.97 in) makes it easy to integrate into benchtop setups, portable rigs, or automated fluidic systems. The direction of flow can be reversed simply by swapping the positive and negative connections, offering flexibility for both forward and reverse pumping scenarios.

Why Choose Us

Choosing the Walfront peristaltic pump means selecting a product built on quality, reliability, and user‑centric design. The transparent silicone tube not only allows real‑time observation of fluid levels but also resists a broad chemical spectrum, including acids, bases, and solvents. Stainless‑steel screws secure the pump head, preventing loosening during prolonged operation. The PC housing is impact‑resistant, protecting internal components from accidental drops or vibrations common in busy laboratory settings. Our pumps undergo rigorous testing for flow consistency, motor durability, and leak prevention, ensuring that each unit meets the high standards expected by scientific professionals. Additionally, Walfront provides responsive technical support and a clear warranty policy, giving customers confidence that any issues will be addressed promptly.

FAQ

Can the pump handle viscous liquids?

Yes, the diaphragm design and flexible silicone tube allow the pump to move both low‑viscosity and high‑viscosity fluids efficiently, making it suitable for oils, gels, and polymer solutions.

How do I reverse the flow direction?

Simply switch the polarity of the DC power connections; the pump will reverse its rotation and change the direction of liquid flow.

Is the silicone tube replaceable?

Absolutely. The tube can be detached without tools, allowing quick replacement for hygiene or when switching to a different chemical compatibility.

What maintenance is required?

Periodically inspect the tube for wear, clean the pump head with a compatible solvent, and tighten the stainless‑steel screws to ensure optimal performance.

Does the pump come with a warranty?

Walfront offers a standard one‑year warranty covering manufacturing defects, and our support team is ready to assist with any technical questions.
