Sludge pumping with hydraulic submersible pumps
World Pumps, 2005In this contribution from the USA, Peter Snow of Godwin Pumps highlights the usefulness of diesel-driven hydraulic submersible pumps in the challenging application of sludge pumping. Advantages include the pumps' variable operating speed and their ability to handle thick sludges without the addition of water.

Hydraulic Pumps for Aeroplanes
Aircraft Engineering and Aerospace Technology, 1937THE past two years have seen a notable increase in the number of services on aircraft for which some form of power is required. First, retractable undercarriages, followed by wing flaps, gun turrets, and automatic pilots, have demanded a light and compact source of power, capable of being transmitted to remote points on the machine.

Hydraulic Laboratory Devices for Testing of Hydraulic Pumps
Advanced Materials Research, 2014Hydraulic pumps are the most important components of hydraulic circuits in agricultural tractors. Their durability is influenced by flow characteristics and thus the flow efficiency. This paper presents the laboratory test of an ecological synthetic hydraulic fluid of UTTO type. This fluid is currently under development.

A Contribution to the Design of Hydraulic Lube Pumps
International Journal of Fluid Power, 2002AbstractWith special reference to gerotor lube pumps the paper details how a simulation environment can be instrumental in design development. The relevance of testing is stressed as an essential counterpart to simulation. Original modelling techniques are also proposed that provide a unified approach to volumetric pumps studies.

1997
To obtain much higher performance than that of alternative power transmission systems, hydraulic systems have been continuously evolving to use “high-pressure”. Adoption of positive displacement pumps and motors is based on this reason. Therefore, tribology is a key technology for hydraulic pumps and motors to obtain excellent performance and ...

Mathematical Modeling of Cavitation in Hydraulic Pumps
IFAC Proceedings Volumes, 1980Abstract It frequently occurs that hydraulic systems break down or are not able to perform satisfactorily because of cavitation (bad filling) in the pump. This matter can be attributed to the wrong construction of the system (suction line) or to the insufficient knowledge of the pump suction property.
