GEAR FLOW DIVIDERS Technical Catalogue

ROTARY FLOW DIVIDERS AND FLOW EQUALIZERS GENERAL FEATURES A ow divider is composed of two or more modular elements (stages) with gears mechanically linked by an internal coupling sleeve, between the shafts, that causes them to turn at the same speed.Unlike multiple pumps, in which the input power is mechanical (shaft connected to a motor), in a ow divider the input power is hydraulic, i.e. a ow of oil under pressure supplies the modular elements, which are in turn connected to the hydraulic circuits serving the users.

ROTARY FLOW DIVIDERS AND FLOW EQUALIZERS 2DRE Typical applications of ow dividers Examples of this kind of application: • lifting platforms and bridges; • hydraulic bending presses and shearing machines; • hoisting of freight containers; • lubrication systems; • hydraulic opening / closing of gates; • automatic hydraulically-driven machines; • actuation of formwork for construction; • wood processing machinery; • conveyance of trolleys driven by hydraulic cylinders or motors; • equipment for the food industry; • military installations. Pressure ampliers. When in a hydraulic system one user requires...

ROTARY FLOW DIVIDERS AND FLOW EQUALIZERS In order to equalize the ow, it needs to maintain the speed within the suggested speed range, with a Δp max. of 50 bar (725 psi) between the different stages.Keeping these conditions, we can assure a ow deviation, within ± 2% on the different stages. n = number of section Salami S.p.A.
