2 2 ourtesy of MA/Flodyne/Hydradyne Motion ontrol Hydraulic Pneumatic Electrical Mechanical (800) Technology with many advantages When it comes to quality, performance and choice of design, the external gear products from exroth set standards. For decades, we at the Mobile Hydraulics Division have successfully been working on the development and production of this efficient, value-for-money technology. The result is external gear products which perform with universal reliability in the most varied branches and which, as a pump or motor, can offer the right configuration for every application. Tried and tested technology The external gear pump uses the most popular pumping method in hydraulics. The products are compact in design and extremely reliable in operation. The price/performance ratio of this method of pressure generation is unrivalled. Proven designs, stringent endurance tests, along with incorporating specially developed materials, guarantee products of the very highest quality. Our intensive system of quality control is one of the crucial factors in the successful employment of exroth external gear products. We manufacture these products all over the world in large numbers for the most varied spectrum of applications that our customers desire. There is scarcely any other type of pump that can satisfy so many different requirements with so little problem as the external gear product.

3 3 ourtesy of MA/Flodyne/Hydradyne Motion ontrol Hydraulic Pneumatic Electrical Mechanical (800) The advantages of exroth external gear products: Low costs over the product's life Modular constructions ompact design Optimum efficiency Multiple pump technology available Option of a single intake port for several pump sections Valve functions can be integrated High quality standard through large-scale production all over the world using uniform manufacturing processes Low air-borne noise levels apid availability exroth provides: A global presence Top quality through the use of automotive quality standards State-of-the-art production technology onstant quality control during production Maximum commitment to delivery deadlines

4 4 ourtesy of MA/Flodyne/Hydradyne Motion ontrol Hydraulic Pneumatic Electrical Mechanical (800) The applications: as diverse as our range exroth external gear products are suitable for applications using operating pressures of up to 300 bar. And depending on the size of the pump, they can also cope with rotational speeds of up to more than 6000 rpm. The range of hydraulic fluids with which they can work is extremely broad and encompasses all the fluids commonly in use today. Thanks to the modular construction of exroth external gear products, they can be used for a virtually unlimited number of customized applications. The principle uses of external gear products are, among others: in agricultural machines, commercial vehicles, industrial trucks and construction machinery.

5 5 ourtesy of MA/Flodyne/Hydradyne Motion ontrol Hydraulic Pneumatic Electrical Mechanical (800) The modular system for a wide variety of applications External gear pumps and motors are hydrostatic displacement machines that are produced in large numbers all over the world. This is due, on the one hand, to the unrivalled price/ performance ratio of this method of displacement. Another key factor is that exroth standard components provide opportunities for a multitude of customized applications. So exroth has developed a modular system with which a huge range of requirements can be satisfied without problem. In addition to a dense range of individual pumps of different sizes, this modular system also contains multiple pumps offering a variety of combinations, pumps with valve technology, plus diverse mounting flanges and line connections.

Pay close attention to the specification, especially speeds, pressures and suction vacuum. Filter recommendations y far the largest number of premature failures or gear pumps are due to contaminated fluid. Since our guarantee does not apply to wear resulting from dirt in the system, we recommend filtering which reduces the size and concentration of the contamination particles to a permitted minimum. Operating pressure [bar] >160 <160 ontamination class NAS ontamination class ISO /15 19/16 Achieved with filter β X = Full-flow filtering is always recommended. The initial contamination of the fluid with which the system is filled must not exceed lass 10 to NAS Past experience has shown that even brand new fluids often exceed this value. In such cases a filter incorporating a special filter will have to be used.

A coupling is fitted between each pair of pumps. In most cases each pump is isolated from its neighbour, i. e. the suction and delivery ports are separate. Note: asically, the specifications for the individual pumps apply, but with certain restrictions: Max. speed: This is determined by the highest rated pump speed in use.

28 28 Valve Options ourtesy of MA/Flodyne/Hydradyne Motion ontrol Hydraulic Pneumatic Electrical Mechanical (800) In order to reduce external pipework it is possible to incorporate a flow control valve or pressure relief valve in the end cover of the pump. A typical application of this is in power-assisted steering systems. The pump delivers a constant flow irrespective of the speed at which it is driven. The excess flow is either returned internally to the suction or distributed externally to other items of equipment. 3-way flow control valve. Excess flow returned to suction 3-way flow control valve.
