Abstract
Embodiments disclosed provide a pump assembly including a first pump for delivering at least one fluid. The first pump may include a first inlet coupled to the first pump for delivering at least one first fluid to the first pump, a second inlet coupled to the first pump for delivering at least one second fluid to the first pump, a first discharge coupled to the first pump for delivering the at least one first fluid at a first pressure, and a second discharge coupled to the first pump for delivering the at least one second fluid at a second pressure. In some embodiments, the first discharge and the second discharge are isolated from each other.

A pump assembly comprising:
- a first line for delivering a first fluid;
- a second line for delivering a second fluid, wherein the first line is coupled to the second line;
- a first pump;
- a second pump;
- a first suction line coupled to the first line and the first pump for delivering the first fluid to the first pump;
- a second suction line coupled to the second line and the second pump for delivering the first fluid and the second fluid to the second pump;
- a third line coupled to the first line and the second suction line coupled to the second pump, the third line for delivering the first fluid to the second suction line coupled to the second pump from the first line;
- a third suction line coupled to the first pump for delivering the first fluid and the second fluid to the first pump;
- a fourth line coupled to the second line, the third line, and the third suction line coupled to the first pump, the fourth line for delivering the first fluid from the third line to the third suction line and for delivering the second fluid from the second line to the third suction line;
- a first discharge line coupled to the first pump for delivering the first fluid from the first pump at a first pressure;
- and
- a second discharge line coupled to the first pump for delivering the second fluid from the first pump at a second pressure, wherein the first discharge line and the second discharge line are isolated from each other;
- and
- a third discharge line coupled to the second pump for delivering the first fluid and the first pressure and the second fluid at the second pressure from the second pump.
