Hydraulic Gear Pumps

S M Shah offers Hydraulic Gear Pumps. These pumps are available in a wide variety of mounting flanges with two and four bolt mountings for easy installation. Gear pumps with displacements of 0.8 cm3/rev to 153 cm3/rev made in aluminium and conforming to SAE-BIS and DIN standards. Direct drive is advisable between the gear pump and the prime mover using a coupling, which will allow self-alignment of shaft. Pumps suction line should be large and free from sharp bends to prevent excessive suction head. A relief valve should be provided to pump outlet so that working pressure of pump is controlled. The reservoir capacity for industrial applications should be three to five times the open loop flow per minute being drawn from the reservoir. For mobile applications, the reservoir should be sized for not less than 0.75 times the open loop flow. Mineral oil based hydraulic fluids are selected as per the requirements of temperature during operation. High tensile aluminum alloy bodies are used throughout the range to ensure uniformity in material properties and maximum fatigue strength. Applications: agriculture tractors, construction equipments, material handling equipment, earth moving equipment, mining, drilling equipment and road paving, etc.
