3 Basic Description DESCIPTION Pumps of series with external gearing are applicable for its simple design, compact dimension and a wide range of types, in modern hydraulic systems, handling technologies and mobile hydraulics. Basic execution is composed from a few parts. The body of pump are produced from heavy duty aluminium alloy. Cover and Flange are from iron grey or aluminium alloy. All flange as well as liquid inlets and outlets (location on side - in body or axial - in cover) comply with all world-recognised standards. Gear wheels with 12 teeth are optimised to achieve a low noise level, are made of ultra high-strength steel. Wheel pins with high quality surface are stored in bearings, which are constantly lubricated and cooled with flow working liquid. Upon requirement on low weight and small size is appropriate a special shortened version (for use by lower continuous pressure) - designation K Available is also multiple-version pumps with inlets for each section or one common inlet.

7 Basic Description 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 of drain 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. (see. picture below). Dimension of hole for external drain are listed in tables in chapter IQUID INET AND OUTET CONNECTION on page verze 01/2014
