Customizing your dosing hoses is crucial to optimize their performance within specific peristaltic or metering pump systems. A tailored approach ensures maximum flex-fatigue life and maintains the critical volumetric accuracy required for chemical injection and sensitive fluid control applications. We provide specialized customization options that focus on the material and dimensional integrity of the tubing. By fine-tuning these four aspects, we guarantee the hose resists premature cracking, maintains its dimensional stability under compression, and remains compatible with the chemical being dosed.
We offer a choice of materials, including Santoprene, silicone, and specialized PVC, specifically matched to the chemical being metered. This customization ensures the hose material does not react with the fluid, preventing swelling, hardening, or chemical degradation that would compromise both accuracy and hose life.
We can adjust the Shore Hardness (Duro A) of the elastomeric material to optimize it for your specific pump roller design and cycle speed. A customized hardness level ensures the hose delivers maximum volumetric efficiency and provides superior flex-fatigue resistance without premature rupture.
We allow customization of the wall thickness to achieve a precise balance between flexibility and pressure rating. A tailored thickness prevents the hose from collapsing under vacuum or expanding under pressure, thereby maintaining consistent internal volume and reliable metering accuracy during operation.
We provide hoses cut to your exact specified length to minimize waste and ensure perfect fit within your equipment housing. Additionally, we can customize the end preparation (e.g., straight-cut, flared, or pre-fitted with specific connectors) for immediate, leak-proof integration into your dosing system.
A dosing hose, often referred to as peristaltic tubing or metering tubing, is a specialized, flexible hose designed for use in chemical dosing pumps, most commonly peristaltic and diaphragm pumps. Its core function is to deliver precise, repeatable, and measured volumes of fluid, which is essential in applications like water treatment, chemical injection, and laboratory analysis.
The hose is characterized by its superior flex-fatigue resistance and tight dimensional tolerances, particularly the inner diameter (ID) and wall thickness. This robust construction ensures the hose can withstand the continuous compression and relaxation cycles generated by the pump rollers without losing its shape, cracking, or suffering a catastrophic failure, thereby maintaining the critical volumetric accuracy required for chemical metering.
A dosing hose is made from highly specific elastomeric materials selected for their outstanding flex-fatigue resistance and chemical compatibility. The primary material consideration is the ability to endure countless cycles of compression and recovery within a peristaltic pump without hardening, cracking, or losing its precise dimensional stability.
The materials used must also be non-reactive with the fluid being metered. This prevents the chemical from degrading the hose structure and ensures that the dose remains pure. Common materials are specialized synthetic rubbers and thermoplastics, each chosen for distinct chemical and mechanical properties.
Santoprene (Thermoplastic Vulcanizate – TPV) Santoprene is widely used for its excellent flex-fatigue resistance, allowing it to endure millions of pump cycles. We utilize this material where aggressive dosing action is required, offering good chemical compatibility with many acids and alkalis commonly used in water treatment.
Silicone Silicone rubber is chosen for its superior flexibility and temperature stability, making it ideal for pharmaceutical, food, and high-temperature laboratory applications. We ensure the material is non-toxic and non-leaching, maintaining purity for sensitive media transfer and dispensing.
Specialized PVC (Polyvinyl Chloride) Modified PVC formulations are used for moderate pressure applications where chemical resistance to general industrial solutions is needed. We select PVC grades that offer transparency for fluid visualization and cost-effectiveness while still providing adequate service life for light-duty metering tasks.
PTFE (Polytetrafluoroethylene) or FEP For metering extremely corrosive or high-purity chemicals that cannot tolerate any leaching, we utilize PTFE or FEP liners. Though less flexible than elastomers, they offer near-universal chemical inertness, often combined with an external jacket to provide the necessary mechanical strength and rigidity.
A dosing hose is used for the critical function of accurately metering, injecting, or transferring precise volumes of fluids, often concentrated chemicals or sensitive media. Its primary application lies in systems that rely on repeatable volumetric control, ensuring process stability, quality control, and adherence to specific blend ratios.
These specialized hoses are essential in processes where fluid quantity directly impacts the final product or treatment effectiveness. They provide the necessary flexible interface for pumps and dispensing equipment, maintaining fluid integrity and preventing pulsation or inaccurate dispensing over long operation periods.
Water and Wastewater Treatment Dosing hoses are used to inject precise amounts of chlorine, coagulants, or balancing agents into water streams. This application is critical for public health and environmental compliance, relying on the hose’s accuracy to maintain correct chemical concentrations.
Chemical Process Control They are integrated into automated systems to inject catalysts, inhibitors, or additives into reaction vessels or pipelines. The reliable, non-pulsating flow ensures consistent blending and reaction kinetics in chemical manufacturing and petroleum refining processes.
Medical and Pharmaceutical Dispensing In these sensitive fields, dosing hoses handle sterile liquids, active pharmaceutical ingredients (APIs), and reagents. Their non-leaching materials and high accuracy are crucial for maintaining product purity and for the precise manufacturing of drugs and diagnostic solutions.
Food and Beverage Blending Dosing hoses are used for injecting flavorings, colorings, concentrates, and preservatives into beverage or food product lines. The hose’s consistent flow rate is essential for ensuring uniform product taste and quality across large production batches.
