CAT PUMPS triplex injection oilfield pumps have been in operation since 1968. CAT PUMPS' precision, triplex, positive displacement design and high pressure ratings allow them to hold hydrostatic pressure for long periods of time for high pressure chemical injection. CAT PUMPS offer liquid-end construction in 316SS and Duplex SS and other special alloys to meet the varying liquids used in high pressure chemical injection. CAT PUMPS deliver a constant head pressure for injection, oilfield transfer and process applications, operate under continuous-duty conditions and require little maintenance.
