637307-R43 ARO REPAIR KIT LOWER PUMP
P/N 637307-R43 ARO Lower Pump Repair Kit
The ARO 637307-R43 Lower Pump Repair Kit is a replacement service kit for compatible ARO 66302-R43 300 Series Stainless Steel two-ball lower pump ends used with industrial air-operated piston pumps. The applicable R43 configuration uses staggered glass-filled PTFE and UHMW-PE upper packings with glass-filled PTFE lower packing. The 66302-R43 lower pump features 300 Series Stainless Steel construction with a tungsten-carbide seat and a hard-chrome-plated 17-4 stainless-steel plunger.
Designed for servicing the lower pump end, the kit provides replacement components used during lower-end service and maintenance. Applicable ARO two-ball piston pumps use a double-acting design that delivers material during 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.
