Positive displacement pump
Ampco Pumps enhanced the traditional design of its ZP1-style pump with the patent-pending ZP1+ positive displacement pump. This advanced design changes the position of the dynamic O-ring for better performance and faster maintenance, the company said. Seal maintenance times are cut in half using ZP1+ technology. ZP1+ dynamic O-rings can be changed without removing the body or disconnecting the pump from the piping system, providing simple maintenance and increased production times. The one-piece sleeve design seals the pump if the rotors are removed for clean-in-place processing.
