P/N 637305-R43 ARO Lower Pump Repair Kit
The ARO 637305-R43 Lower Pump Repair Kit is a replacement service kit for compatible ARO 66300 series 300 Series Stainless Steel lower pump ends used with industrial two-ball piston pumps, including hydraulic-operated configurations. The applicable R43 configuration uses staggered glass-filled PTFE and UHMW-PE upper packings with glass-filled PTFE lower packings.
Designed for servicing the lower pump end, the kit provides applicable replacement O-rings, a gasket, and upper and lower packings used during routine lower-end maintenance. Applicable ARO two-ball pumps are designed for pumping medium-viscosity fluids compatible with 300 Series Stainless Steel. The two-ball lower pump design supports improved priming, while double-acting operation delivers material to the discharge on both the upstroke and downstroke.
Please verify your complete pump model and lower pump-end configuration before ordering to ensure this is the correct repair kit. This is a service kit only and is not a complete pump or lower pump-end assembly.
