The main constraint in this case is the pumped fluid. Betaine, one of the primary surfactants used in detergents and other formulations for personal and household care, is corrosive and could deteriorate pump materials over the medium to long term. Therefore, a 1/2" (13 mm) UP05 pump from the PIVOT series was chosen. This pump can reach a flow rate of up to 51 l/min (13.5 gal/min). Its fluid chambers and manifolds are made of PVDF. The valve seats and valve balls are made of Teflon, and the diaphragms are made of PTFE (Teflon with Santoprene). Other key aspects that led the customer to choose our pump include:
- Proven air motor: The patented "Smooth Start Shifter" (3S) actuator ensures a reliable start system, preventing the pivot from stalling. Furthermore, the air is discharged directly into the atmosphere through two large evacuation ports, preventing freezing and pump slowdown.
- Easy maintenance: The pneumatic motor of the PIVOT series pumps has the fewest moving parts in the market, and its assembly is effortless due to the cartridge design. The air valve module can be replaced in a few minutes without removing the pump from service.
- Reduced air consumption: Thanks to the rapid movement of the pivot, air consumption is reduced and the output flow is optimized compared to the competition.
- Universal pump standards: Matches the relative dimensions of main competitive brands, allowing for an easy swap-over.
