STP 1310 is the only publication of its kind addressing the critically important area of modeling and testing hydraulic fluid lubrication regimes in hydraulic pumps. In addition to an in-depth overview, 28 comprehensive peer-reviewed papers cover the following keyareas:

Lubrication Fundamentals -- 4 papers explore the potential application of basic tribological principles to solve lubrication problems arising from a broad range of pumps and motors.

Pump Testing -- A comprehensive selection of the most commonly used pump tests as well as new pump testing proposals are addressed in 15 papers.

Fluid Cleanliness -- 3 papers examine the predictability of fluid contamination on pump wear.

Bench Test Development -- Innovative bench testing procedures currently under evaluation to enhance or replace current testing approaches are explored in 6 papers.

This publication is an invaluable resource for hydraulic mainten and and systems engineers, hydraulic pump manufacturers, designers and test personnel, oil manufacturers and producers, end users of hydraulic equipment, and fluid formulation specialists.
