B-TEC leverages custom pump from Xylem’s Flojet portfolio to redefine precision spray gun cleaning for the industrial paint sector
Customer Challenge
In industrial paint environments, silicone contamination poses a critical risk to finish quality and process stability. Even trace amounts can prevent proper adhesion, leading to defects like fisheyes, blistering, or patchiness. These issues may not be visible until final inspection and often require a full rework, resulting in lost materials, time, and productivity.
Silicone creates a barrier that prevents paint from bonding to the surface of the material being painted (typically metal or plastic in automotive applications). Because it is difficult to detect and nearly impossible to remove once introduced, paint shops – particularly in OEM settings – enforce strict no-silicone protocols.
Did you know?
Even a single drop of silicone can ruin an entire automotive paint job, causing defects that result in full rework, lost materials, and costly downtime.
Because silicone is airborne and highly adhesive, it can spread invisibly through a facility, making contamination control a constant challenge.
B-TEC’s customers depend on cleaning systems that meet these requirements. They also need equipment that performs reliably across a variety of use cases, from fast-paced factory cycles to more targeted cleaning jobs in the field. To drive chemical cleaning fluid through spray guns effectively, B-TEC required a compact, high-performance pump capable of delivering consistent pressure and flow across a wide range of chemical solvents.
Xylem Solution
To meet this challenge, B-TEC partnered with Xylem, a global water technology leader and trusted collaborator for more than 20 years. Together, the teams co-developed a customized version of Xylem’s Flojet G70 Series air-operated diaphragm pump, designed specifically to integrate with B-TEC’s spray gun cleaning machines and meet the industry’s most rigorous contamination control standards.
Engineered for reliability, Flojet diaphragm pumps deliver consistent performance in high-demand applications.
The pump was engineered using chemically resistant thermoplastics and high-performance elastomers, selected for their ability to withstand a wide range of industrial solvents, including aggressive compounds like acetone, MEK, and others commonly used in ATEX regulated environments. Every component was carefully validated to ensure long-term durability, stable performance, and full compliance with B-TEC’s silicone-free requirements.
Delivering a flow rate of up to 19 liters per minute, the pump provides consistent, pressurized cleaning – crucial for removing paint residue from spray guns in high-throughput environments like automotive body shops and production lines. At the core of the design is the G70’s dual diaphragm configuration, which ensures smoother operation and more stable fluid control than single-diaphragm alternatives.
Built for operation flexibility, the pump also includes self-priming capability, dry-run tolerance, and a quick-connect mounting system that allows on-site replacement in under 15 seconds. Its compact footprint fits seamlessly into the d-800’s modular design and simplifies field servicing.
Customer Result
Since integrating the customized Flojet G70 into its d-800 system, B-TEC has delivered more than 20,000 spray gun washers globally, reflecting strong demand for a high-performance, contamination-safe spray gun cleaning solution. Customers report up to 50% faster cleaning cycles, easier maintenance, and greater confidence in silicone-free operation. These improvements are especially important in automotive paint environments, where even minor contamination can lead to costly production delays. The G70’s plug-and-play design also supports B-TEC’s efforts to streamline assembly and field service.
Designed for precision and reliability, B-TEC’s cleaning systems support high-precision paint operations across automotive, aerospace, and industrial sectors.
The pump’s modular design enables B-TEC to ship systems with flexible final assembly, improving responsiveness and delivery. Additional benefits include strong reliability, reduced servicing needs, and lower air consumption compared to comparable models, contributing to energy savings and reduced operating costs.
