2 DESCIPTION Basic Description series are particularly designed to be used in mobile hydraulic systems of agricultural, heavy construction and road building machines as well as in advanced hydraulic systems of material handling devices. The series covers the range of displacements from 10 to 100 cm 3 /rev. The pumps are characterized by simple construction with hydraulic pressure balance, compact dimensions and a wide range of connection types. pumps have a two-piece all-cast-iron construction. The basis consists of a supporting body with a blind chamber for gear wheels and a fastening flange. The body as well as the flange are made of a high-quality grey cast iron. In the body and the flange, sliding sleeves for gear wheels are molded. Gear wheels with 12 teeth made of ultra high-strength steel, which are optimised to achieve a low noise level. The axial pump balancing is performed using sliding aluminium alloy pressure plates in which a shape sealing of balancing surface is located in grooves. For heavy duty with a weight-bearing drive shaft, the pumps can be equipped with front-end roller bearings. construction enables the pumps to be used already at low revolutions at high pressure. pumps are produced in various designs of divers clamping flanges as well as liquid inlets and outlets. These pumps comply with the standards ISO, SAE, UNI and other world-recognised standards and can be delivered in simple or multiple designs. They can also be delivered in a reversible design, with external or internal drainage. BASIC PATS OF PUMP 1. Body 9. Shaft seal 2. Flange 10. Peripheral sealing 3. Driving gear 11. Spring washers 4.

6 Basic Description OTHE EQUIEMENTS A driving device must not generate an axial or a radial load of the pump shaft, unless this is exclusively permitted for the pump with a front-end bearing. All the matters affecting technical parameters and properties of the pump are given in respective operating manuals, technical specifications and test specifications of the manufacturer. DIECTION OF OTATION Determine direction of rotation by looking at the drive shaft. The pump can only be used in the specified direction of rotation. EVESIBE DESIGN The pumps with the possibility of bidirectional rotation have a different internal arrangement requiring drainage. Two types are used - internal and external. The internal drainage is always interconnected with the outlet by means of valves. The external drainage is solved by an orifice located in the cover opposite the driven gear. 6 version 01/2015
