From the beginning of the secondary recovery program in the petroleum industry, positive displacement pumps have been successfully used to inject water for flood and pressure maintenance and for salt water disposal. Pressures have gradually increased from deeper and tighter floods and available waters have become more corrosive and difficult to handle. For the past decade and more, these plunger waterflood pumps were plagued by a large number of fluid end failures, caused by the increased pressure demands, the worsening water conditions, misunderstood piping requirements, and unsatisfactory quality in fluid cylinders. Considerable progress has been made in design of piping systems to minimize pressure surges and water hammer.(1) Control and treatment of produced and natural water systems to minimize corrosion and avoid formation damage has become a science in itself. In addition, design modifications and better material use has resulted in improved life of the injection pump fluid chamber.
