Peristaltic Chemical Pumps for Safe Chemical Dosing

When transferring corrosive or hazardous fluids, a reliable and leak-free peristaltic chemical pump is crucial. These pumps provide safe and precise fluid handling without the risk of leaks or contamination, making them ideal for chemical dosing and transfer applications across a wide range of industries.

Chemical Compatibility and Containment

Verderflex peristaltic hose pumps for chemicals are designed for durability and total fluid containment. The pumped fluid is fully enclosed within the hose or tube, eliminating the need for mechanical seals or valves and ensuring zero cross-contamination.

Verderflex hoses are engineered for compatibility with aggressive and corrosive chemicals including sodium hypochlorite, sodium hydroxide, calcium hydroxide, cyanide, plating solutions, catalytic agents, sulfuric acid, and a variety of organic solvents and resins. 

These pumps can also handle challenging media such as slurries, viscous fluids, and gases - making them suitable as a peristaltic pump for gases or for chemical transfer in aeration systems and dosing applications. The wide range of available hose materials allows operators to match the right hose to the chemical, ensuring long service life and maximum safety.

Key Features of Peristaltic Chemical Pumps

• Leak-free operation: The closed hose system prevents leaks, ensuring operator safety and chemical containment.
• Self-priming and dry running: The pump can self-prime and run dry without damage, reducing operational risks.
• Low maintenance: Simple hose replacement means shorter downtimes and minimal maintenance costs.
• Precision dosing: Provides highly accurate, repeatable flow control - ideal for chlorine, sodium hypochlorite, and other chemical dosing applications.
• Gentle pumping action: No valves or seals, meaning low shear and no damage to delicate fluids or chemical structures.

Peristaltic chemical dosing pumps are particularly suited for handling shear-sensitive chemicals and slurries while maintaining consistent flow rates.

Applications: Dosing, Transfer and pH Control

Peristaltic hose pumps play an important role in dosing and pH correction processes. In industrial wastewater treatment, for example, peristaltic pumps are used to dose chemicals such as iron sulphate or iron chloride to remove phosphates from effluent. Precise dosing prevents excess iron content while ensuring complete phosphate removal.

The same pump may also be used to adjust pH levels by dosing sodium hydroxide or lime. These processes demand high accuracy, making Verderflex pumps the preferred choice for consistent and repeatable dosing.

They are also commonly used as a peristaltic chlorine pump in water treatment and disinfection systems, providing safe, leak-free dosing of chlorine and other sanitising chemicals.

In Australia, peristaltic chemical pumps are widely used across industries such as:

• Water treatment
• Mining
• Chemical manufacturing
• Food and beverage production.

Their robust design and proven reliability make them ideal for challenging environments where performance and safety cannot be compromised.
