The adhesives and sealants industry is the hidden backbone of modern manufacturing, providing the crucial bonds and seals that hold everything from aeroplanes to consumer electronics together. While often unseen, the fluids that create these products are among the most difficult to handle. We have long recognised that the unique properties of adhesives and sealants, particularly their high viscosity, abrasiveness, and propensity to cure, present a significant challenge to conventional fluid transfer technologies. As a leading diaphragm pump manufacturer, we specialise in creating solutions for these exact applications. The diaphragm pump stands as the ideal technology for this sector, offering precision and durability where other pumps fail. Our range of industrial diaphragm pumps is engineered to meet these unique demands head-on.

The Challenges in the Adhesives and Sealants Industry

The materials that make up adhesives and sealants are highly diverse, ranging from thick pastes to fine suspensions and reactive liquid systems. Pumping these fluids presents a series of fundamental challenges that must be addressed to ensure product quality, process efficiency, and operational safety.

• ‍High Viscosity and Abrasive Components: Many adhesives and sealants are extremely viscous, with consistencies ranging from thick honey to putty. This high viscosity requires a positive displacement pumping mechanism that can move the material without losing efficiency or cavitating. Furthermore, many formulations contain abrasive fillers and pigments (such as fumed silica or talc) that can cause rapid wear on the moving parts of traditional pumps, leading to costly failures and frequent maintenance. This constant abrasion erodes impellers, gears, and mechanical seals, making conventional pumps a liability in a continuous production environment. The thicker the fluid, the more resistance it presents, demanding a pump that can generate sufficient force without overheating or succumbing to internal friction.‍
• Chemical Aggressiveness and Reactive Nature: Modern adhesives often rely on aggressive chemical components to achieve their high-performance properties. These include acids, solvents, and catalysts that can corrode standard pump materials over time. Additionally, many adhesives are multi-component systems (e.g., epoxies) that begin to cure upon mixing, which poses a significant risk of solidification within the pump if not handled correctly. This necessitates a pump with a design that is easy to clean and does not allow for product build-up in internal passages. The reactive nature of these fluids means that any component that allows for ingress of air or moisture can trigger a premature curing process, potentially blocking lines and causing catastrophic system failure.‍
• The Need for Uncompromising Precision: Many high-performance adhesives, particularly two-part reactive systems, rely on an exact mixing ratio to achieve their desired bond strength and cure time. Inaccurate dosing can lead to a weak or incomplete cure, rendering the final product unusable and creating significant material waste. This necessitates a pump that can deliver precise, repeatable, and consistent flow, especially for automated and robotic application systems. In applications such as the automotive industry or electronics, where a flawless bond is critical to performance and safety, a small deviation in the ratio can result in a total product failure, leading to expensive rework or costly recalls.

Fit-for-Purpose Solutions

Our pumping solutions are specifically designed to address these challenges, ensuring reliable, precise, and safe fluid transfer for even the most demanding adhesives and sealants.

• ‍Gentle, Low-Shear Transfer: Our double diaphragm pump and other models operate with a gentle, reciprocating motion that applies minimal shear to the fluid. This is critical for shear-sensitive materials, such as acrylics and silicones, where excessive agitation could alter the product's viscosity or chemical properties. Unlike centrifugal or gear pumps that can aggressively churn the fluid, our positive displacement mechanism moves the material in a smooth, pulse-like motion, preserving the product's integrity from the initial transfer from a drum to the final application point. This gentle handling ensures that the chemical composition and physical properties of the adhesive remain unchanged throughout the process.‍
• Material Compatibility: We offer our pumps in a variety of corrosion-resistant materials, including stainless steel, polypropylene, and PTFE. This allows us to create a bespoke chemical diaphragm pump that is compatible with even the most aggressive solvents and reactive components. For instance, PTFE diaphragms and valve seats provide exceptional chemical resistance, making them ideal for handling aggressive acids and isocyanates. For water-based or less corrosive adhesives, we can offer more economical polypropylene options, ensuring a tailored solution for every formulation. By selecting the right combination of materials for the pump body, diaphragms, and valve seats, we ensure the pump's longevity and prevent contamination of the fluid.‍
• Seal-less Design for Zero Curing: The inherent design of our pumps eliminates the need for dynamic seals, which are common failure points in other pump technologies. This is a critical advantage for the adhesives industry, as it prevents material from leaking and curing in the pump's crevices and between moving parts. The straightforward design also makes our pumps exceptionally easy to disassemble for cleaning and maintenance, greatly reducing the risk of a solidified blockage and subsequent downtime. This seal-less advantage is not just a matter of convenience; it is a fundamental design feature that ensures reliable operation and reduces a significant source of downtime and product loss.

Ovell's Pumps for Various Industries

Our extensive product line offers a range of ideal solutions, each tailored to specific applications within the adhesives and sealants industry.

• ‍Diaphragm Metering Pumps: For applications requiring the highest level of precision, our diaphragm metering pump is the ideal solution. It ensures the accurate and repeatable dosing of two-part adhesives and sealants, guaranteeing the correct mixing ratio for optimal performance. This technology is indispensable for manufacturers seeking to automate their assembly processes and eliminate the guesswork of manual mixing. Our advanced diaphragm metering pump models can be integrated into programmable logic controllers (PLCs) to allow for real-time flow rate adjustments and monitoring, providing total control over the application process.‍
• Electric Pumps: Our electric diaphragm pump offer a different set of advantages. They are highly energy-efficient and provide a smooth, low-pulsation flow that is ideal for continuous feeding applications. Their precise speed control allows for accurate flow rate adjustment, making them an excellent choice for automated production lines where consistent output is essential. They are also a quieter alternative to air-powered pumps, which can be a key consideration in certain manufacturing environments.‍
• Handling Difficult Fluids: Our pneumatic powder diaphragm pump provides a unique solution for manufacturers who use powdered fillers, pigments, or binders in their formulations. It can safely and efficiently transfer these dry materials, preventing airborne dust and ensuring a clean, contained process. For high-volume transfer tasks, our larger models, such as the 2 inch diaphragm pump, offer the capacity and power to move vast quantities of high-viscosity materials quickly and reliably.

Lowering Total Cost of Ownership

While a pump's initial purchase price is a factor, the total cost of ownership (TCO) is the true measure of its value. Our pumps are designed with TCO in mind, offering significant savings over their operational lifetime. The durability and reliability of an Ovell pump translate into less frequent breakdowns and a substantial reduction in maintenance labour and parts costs. By minimising material waste through our pumps' precision and efficient fluid transfer, we help our clients maximise the value of every litre of adhesive. This is particularly important for high-cost, high-performance formulations. The increased operational uptime our pumps provide directly boosts productivity and profitability, proving that a quality, purpose-built pump is an investment that pays for itself many times over.
