A pump discharge pulsation dampener system comprising: a pump discharge pulsation dampener comprising: an inlet to a body of the discharge dampener; first and second outlets from the body, each in fluid communication with the inlet and each configured to allow fluid discharge from the body; wherein a selected one of the first and second outlets is open and configured to discharge fluid from an interior volume of the body while the other of the first and second outlets is closed, wherein the selected one of the first and second outlets is selected based on a flow rate of the fluid pumped through the inlet into the interior volume of the body and discharged through the selected one of the first and second outlets; a first member connected to or inserted into the first outlet and configured to contribute to discharge dampening, the first member having a fluid passage with a first inner diameter sized to produce a first pressure drop in the fluid pumped into the interior volume through the inlet and discharged through the first outlet, the first pressure drop contributing more to dampening of pressure pulses in the fluid when the fluid is pumped at a first flow rate than at a second flow rate different from the first flow rate; and a second member connected to or inserted into the second outlet and configured to contribute to discharge dampening, the second member having a fluid passage with a second inner diameter different than the first inner diameter sized to produce a second pressure drop different from the first pressure drop in the fluid pumped into the interior volume through the inlet and discharged from the second outlet, the second pressure drop contributing more to dampening of pressure pulses in the fluid when the fluid is pumped at the second flow rate than at the first flow rate. an inlet to a body of the discharge dampener; first and second outlets from the body, each in fluid communication with the inlet and each configured to allow fluid discharge from the body; wherein a selected one of the first and second outlets is open and configured to discharge fluid from an interior volume of the body while the other of the first and second outlets is closed, wherein the selected one of the first and second outlets is selected based on a flow rate of the fluid pumped through the inlet into the interior volume of the body and discharged through the selected one of the first and second outlets; a first member connected to or inserted into the first outlet and configured to contribute to discharge dampening, the first member having a fluid passage with a first inner diameter sized to produce a first pressure drop in the fluid pumped into the interior volume through the inlet and discharged through the first outlet, the first pressure drop contributing more to dampening of pressure pulses in the fluid when the fluid is pumped at a first flow rate than at a second flow rate different from the first flow rate; and a second member connected to or inserted into the second outlet and configured to contribute to discharge dampening, the second member having a fluid passage with a second inner diameter different than the first inner diameter sized to produce a second pressure drop different from the first pressure drop in the fluid pumped into the interior volume through the inlet and discharged from the second outlet, the second pressure drop contributing more to dampening of pressure pulses in the fluid when the fluid is pumped at the second flow rate than at the first flow rate. <EOS>
