A-L Equipment has been a trusted name in liquid handling systems since 1955, when it was founded by Art Nelson and his wife Gerry. Art had already built a reputation for successfully installing pumps where others said it couldn’t be done, which eventually led to his departure from his previous employer. This experience inspired him to start A-L Equipment, where he could operate on his own terms and continue delivering innovative solutions. Over the years, the company has remained family-owned and operated, with each generation taking the business forward. Dean Nelson, Art’s son, joined the company next, expanding its reach across Chicagoland and into parts of Indiana. In 1996, Michael Nelson, Art’s grandson, came on board, and his wife Mercedes followed in 2010. Today, as Vice President, Mike continues the legacy of providing top-quality liquid handling solutions, representing the full line of Viking Pumps since the company's inception. A-L Equipment is based in Glendale Heights, Illinois, where it relocated in 1988 to a custom-built facility that now spans over 17,000 square feet. This space allows them to maintain one of the largest inventories in the industry, with over $4 million in new and spare parts, including approximately $2 million in Viking products. The facility also houses all 16 employees, including warehouse staff, sales teams, and administrative personnel, ensuring efficient operations and quick response times. The company serves a wide range of industries, including raw chemical production, food and pharmaceutical processing, and green technology—particularly biodiesel and ethanol. A-L Equipment prides itself on offering a comprehensive selection of high-quality products, such as pumps, meters, and durable hose and reel systems. Their factory-trained staff and service vehicles ensure customer satisfaction, while their ability to customize pumps in-house allows them to meet specific needs quickly and effectively. One of A-L’s most notable partnerships is with Viking Pump, which has been the largest single product line represented by the company since 1955. In 1993, A-L exceeded $1 million in sales and became a member of the Viking President’s Club, a distinction they have maintained ever since. Mike Nelson emphasizes that they carry everything Viking produces, especially the Mag drive type seals, which are ideal for handling hazardous or sensitive fluids. Relationships are key to A-L’s success, and they have built long-term partnerships with major clients like Barry Callebaut, one of the world’s largest chocolate manufacturers, and Stepan, a global chemical solutions provider. These relationships have led to the installation of hundreds of Viking pumps at various facilities, often using specialized technologies like the O-Pro™ Barrier seal. A memorable moment came when BASF contacted A-L on Thanksgiving evening with an urgent issue that threatened to shut down an entire plant. Using their extensive inventory and technical knowledge, A-L provided a Q-size Viking pump that met the required pressure specifications by applying a lesser-known rule: reducing speed can double discharge pressure. Within 6–8 hours, the replacement was in place, avoiding a costly delay that would have taken 12 weeks with a competitor. A-L Equipment has also customized Viking pumps for unique applications, such as modifying Glycol pumps with de-icing units for airport fueling during winter. This innovation led to collaborations with OEMs who use Viking pumps in glycol de-icing skids for major airlines like UPS and FedEx. With a strong partnership with Viking Pump, A-L Equipment continues to solve complex pumping challenges, from the thinnest liquids like ammonia to the thickest materials like asphalt. Their commitment to quality, innovation, and customer service ensures that they remain a leader in the industry. For more information about A-L Equipment, visit their website.

Seal Ring

A seal ring is a crucial component used in various mechanical systems to prevent the leakage of fluids or gases. It is designed to fit snugly between two mating surfaces, creating a barrier that restricts the flow of the substance being sealed.
There are different types of seal rings, each with its own characteristics and applications. One type is the single seal. A single seal ring provides a basic level of sealing and is often used in less demanding applications where the pressure and temperature conditions are relatively moderate. It consists of a single ring that forms a seal between the rotating and stationary parts of a system.
Component seals are another type. These are seals that are made up of multiple individual components. Each component plays a specific role in the sealing process. Component seals can offer more flexibility in design and can be customized to fit specific requirements. They are often used in applications where a combination of different sealing functions is needed.
The double seal is another option. As the name suggests, it consists of two seal rings arranged in series. The double seal provides enhanced sealing performance compared to a single seal. It can handle higher pressures and is more reliable in preventing leakage. It is commonly used in applications where a higher level of safety and sealing integrity is required.
Double Mechanical Seal is a specific type of double seal that uses mechanical means to maintain the seal. It typically consists of two sets of stationary and rotating seal faces. The double mechanical seal offers excellent sealing performance even under harsh operating conditions. It is often used in critical applications such as in pumps handling corrosive or hazardous fluids.
In conclusion, seal rings are essential for maintaining the integrity of mechanical systems by preventing leakage. The choice of seal ring type, whether it is a single seal, component seals, double seal, or double mechanical seal, depends on the specific requirements of the application, including factors such as pressure, temperature, fluid type, and the level of sealing reliability needed.
