Claim:
1. A housing assembly for a side-by-side (SBS) piston pump having a first piston pump with a first cylindrical pump barrel and a first longitudinal axis and a second piston pump having a second cylindrical pump barrel and a second longitudinal axis, the housing assembly comprising: a first end surface; a second end surface disposed opposite the first end surface; a pump cavity surface extending from the first end surface to the second end surface and encircling the first piston pump and the second piston pump so that the first end surface, the second end surface and the pump cavity surface define a pump cavity in which the first piston pump and the second piston pump are contained, wherein the pump cavity surface includes a first side portion and a second side portion disposed opposite the first side portion, and wherein the first piston pump and the second piston pump are arranged side-by-side with the first longitudinal axis parallel to the second longitudinal axis; and a shroud plate extending from the first side portion of the pump cavity surface toward the second side portion in a fluid intersection area between the first piston pump and the second piston pump, wherein the shroud plate has a plate length parallel to the first longitudinal axis and the second longitudinal axis that is at least equal to a longitudinal length of the first pump barrel and the second pump barrel and the shroud plate is positioned between the first cylindrical pump barrel and the second cylindrical pump barrel so that the shroud plate extends at least to a first barrel end of the first cylindrical pump barrel and the second cylindrical pump barrel that is closest to the first end surface and at least to a second barrel end of the first cylindrical pump barrel and the second cylindrical pump barrel that is closest to the second end surface, and wherein the shroud plate allows fluid flow around the shroud plate in areas within the pump cavity that are not between the first cylindrical pump barrel and the second cylindrical pump barrel.
