Sherwood makes both Major and Minor maintenance/repair kits for many of their pumps. Thes kits have more parts than a simple Impeller Kit and can be generalized as follows: Minor Kits usually include the Seal Assembly, an O-ring or Gasket, and the Impeller. They may also contain additional minor parts such as keys and retaining rings. Major Kits usually contain all of the internal components of the pump, except the shaft (although #18655 and #19354 do include the shaft).
