Abstract

See full text

A housing assembly for a side-by-side (SBS) piston pump may define a pump cavity enclosing first and second piston pumps having parallel longitudinal axes. The housing assembly may include a shroud partially or wholly separating the piston pumps to substantially reduce churning of lubricating fluid flow flowing around the piston pumps and pooling in a fluid intersection area between the piston pumps. The shroud may be a planar shroud plate extending between the piston pumps, or a curved shroud plate between the piston pumps and having sections partially encircling each of the piston pumps. The shroud may alternatively be first and second shroud portions extending inwardly from the cavity walls and directing the lubricating fluid flows the merge in a combined lubricating fluid flow area.
