The chemical industry operates on a foundation of precision and caution, where the safe and efficient transfer of fluids is paramount. This sector, which produces everything from raw materials for manufacturing to life-saving pharmaceuticals, faces a unique set of challenges. The fluids handled are often corrosive, flammable, or toxic, and their mishandling can lead to severe consequences for personnel, the environment, and a company’s bottom line.

Selecting a pumping solution that can withstand these demanding conditions is a critical decision that directly impacts operational safety and productivity. For this reason, the pneumatic diaphragm pump has become a cornerstone of fluid management in chemical plants worldwide. Its robust design and inherent safety features make it a reliable choice for the most hazardous applications. As a leading diaphragm pump manufacturer, Ovell has engineered its solutions to meet and exceed these exacting standards. It is however, vital to first understand some known corrosive chemicals that the chemical processing industry handle on a daily basis.

Understanding the Hazards of Chemical Fluids

The chemical industry deals with a diverse range of substances, each with a unique set of properties and potential dangers. Effective fluid transfer requires not only an understanding of the chemical's characteristics but also a pumping system that is specifically designed to handle them. The failure to do so can lead to a multitude of issues, from material degradation to hazardous spills.

Sulfuric Acid

Sulfuric acid, a key industrial chemical, is highly corrosive and can cause severe burns upon contact. It can react with many common metals, corroding pump components and leading to structural failure. Traditional pumps with metallic housings or mechanical seals are vulnerable to this acid's aggressive nature, resulting in leaks and costly maintenance. Pumping solutions for sulfuric acid must be made from chemically inert materials like polypropylene, PTFE, or stainless steel alloys specifically designed for such applications. The pump must also have a design that minimises the points where leaks can occur, protecting both the fluid's purity and the personnel handling it.

Acetone

Acetone is a highly volatile and flammable solvent. When transferred, it can release vapours that are easily ignited by a spark, such as those generated by an electric motor. This makes conventional electrically-powered pumps a serious fire and explosion risk in facilities handling such chemicals. Pumping solutions for these materials must be intrinsically safe and designed to eliminate any potential ignition sources. This requires a pump that can operate without electricity in a potentially hazardous atmosphere.

Abrasive and Viscous Slurries

Many chemical processes, from pigment manufacturing to mining applications, involve the transfer of slurries and other fluids containing suspended solid particles. These particles can act like sandpaper on a pump's internal components, causing rapid wear and tear. Pumps with impellers or pistons are particularly susceptible to this abrasion, leading to a quick loss of efficiency and frequent part replacements. An effective solution must be able to move these fluids gently without causing damage to the pump itself.

How Diaphragm Pumps Address These Challenges

The design of an industrial diaphragm pump is a direct response to these critical challenges. Its unique operating principle—using a flexible diaphragm to displace fluid—provides a host of advantages that make it an ideal choice for the chemical industry. Ovell’s diaphragm pump range leverages these benefits to provide safe, reliable, and efficient fluid handling.

• ‍Seal-less Design for Ultimate Containment: A primary advantage of a double diaphragm pump is its seal-less design. It uses a diaphragm to create a physical barrier between the fluid and the pump's mechanical components. This design eliminates the need for mechanical seals, which are common points of failure in other pump types. The absence of seals makes the pump leak-free, providing a crucial layer of protection against the escape of toxic, corrosive, or flammable fluids. This feature is particularly vital for maintaining safety and preventing environmental contamination.
• ‍Material Compatibility: Ovell understands that chemical resistance starts with material selection. Their chemical diaphragm pump models are available in various constructions, including polypropylene, aluminium alloys, and stainless steel, to ensure compatibility with a wide range of chemicals. The diaphragms themselves are often made from high-performance materials like PTFE or Santoprene, which are chosen for their exceptional resistance to both chemical attack and abrasion. This careful engineering ensures that the pump's wetted components will not degrade when exposed to aggressive fluids, guaranteeing long-term performance and reducing the risk of contamination.
• ‍Intrinsic Safety: The air operated double diaphragm pump is intrinsically safe for use in hazardous areas. Since it is powered by compressed air rather than electricity, it contains no electric motors or spark-producing components. This makes it the preferred choice for handling flammable or volatile fluids, as it completely eliminates the risk of an ignition source. This inherent safety feature is a significant benefit in industries where maintaining a non-explosive atmosphere is a regulatory requirement.
• ‍Versatility in Fluid Handling: The positive displacement action of a diaphragm pump allows it to handle fluids with a wide range of viscosities. It can effectively transfer thin liquids, thick pastes, and abrasive slurries without losing efficiency. This versatility makes a single pump model suitable for multiple applications within a facility, simplifying inventory and maintenance. Additionally, a diaphragm pump can run dry indefinitely without sustaining damage, a valuable safeguard against unexpected process interruptions.

Ovell’s Pumping Solutions

Ovell offers a diverse portfolio of pumps, each designed to meet the specific requirements of different chemical industry applications. As a trusted diaphragm pump manufacturer, our product line is engineered for performance, durability, and operational efficiency.

• ‍Pneumatic vs. Electric Diaphragm Pumps: The choice between a pneumatic diaphragm pump and an electric diaphragm pump often depends on the application. Air operated diaphragm pump models are ideal for hazardous areas due to their intrinsic safety. They are also highly durable and easy to maintain. In contrast, an electric double diaphragm pump provides a high degree of flow control, making it perfect for precision applications like diaphragm metering pump tasks. These pumps offer precise control over flow rates and are often used for dosing and batching.‍
• Solutions for Abrasive and Dry Materials: Ovell’s product line includes specialised pumps for challenging materials. The pneumatic powder diaphragm pump is engineered to transfer dry bulk materials, such as powders and granules, cleanly and efficiently. This eliminates the need for complicated conveying systems and minimises dust in the working environment. For abrasive slurries, a robust air powered diaphragm pump with durable diaphragm materials offers a reliable solution.‍
• Optimising for Scale: The range of Ovell's industrial diaphragm pumps are designed to meet various volume and flow rate requirements. For high-volume transfer, the 2 inch diaphragm pump provides the necessary capacity to move fluids quickly and efficiently, a crucial feature for large-scale operations. Ovell's commitment to quality ensures that every pump, regardless of size, provides consistent and reliable performance.
