Generally speaking, every single part that makes up the pump can be purchased as a spare part. However, in order to make the purchase and the handling of spares easier, producers do not just offer the loose parts, but also some specific kits including the necessary components in the correct quantities to repair a specific part of the pump. These kits were obviously conceived for the pump parts which are more exposed to wear. We therefore find kits including suction and delivery valves, seal kits, connecting rod kits, oil seal kits and so forth. All of these are strictly original.
