Ruhrpumpen CPO-L ASME/ANSI PumpRUHRPUMPEN makes the CPO and CPO-L (coming soon) to meet or exceed ASME/ANSI B 73.1 specifications. The CPO-L will be available later in 2017 and is a low flow, high head model. RUHRPUMPEN CPO models offer standard features that the competition sell as add-ons. There are only three power ends to simplify the selection process and reduce costs. They are interchangeable with other manufacturer’s models.
