The rotating group of a piston pump is comprised of a cylinder barrel that is rotated by a shaft; seven or nine pistons installed in the cylinder block with brass shoes attached. As the cylinder block turns the pistons travel in and out of the bore of the block. This is how the flow is generated. During service it is suggested that if pistons are to be replaced all should be changed. At CTP, we sell all these parts individually or as a complete group. These groups are listed below:
