P/N 637291-P43 ARO Lower Pump Repair Kit
The ARO 637291-P43 Lower Pump Repair Kit is specifically engineered for servicing and maintaining compatible stainless steel industrial chop-check pump lower ends, such as the 67101-P43 model. This comprehensive repair kit provides the essential internal replacement components required to restore optimal high-viscosity fluid transfer efficiency, prevent fluid bypass, and maintain reliable double-acting performance in demanding extrusion applications.
Inside the package, the kit supplies vital overhaul wear items—including specialized packing materials like UHMW-PE and glass-filled PTFE, upper and lower seals, and internal check components—tailored to restore the pump's internal fluid chamber integrity. Built to support continuous-duty processing environments involving corrosive or reactive media, these precision-engineered replacement parts ensure proper chemical compatibility and help eliminate pressure drift, uneven stroke delivery, or leakage during high-pressure dispensing tasks.
Proper maintenance involves isolating the system from air pressure, safely bleeding off all line fluid pressure, and following precise reassembly procedures to ensure tight seals and proper valve response. Routine servicing with genuine ARO rebuild kits minimizes operational downtime, protects downstream equipment, and extends the overall working life of your industrial chop-check pump systems.
