QHD2 Gear Pump Cataogue DESCIPTION n QHD2 series are particuary designed to be used in mobie hydrauic systems of agricutura, heavy construction and road buiding machines as we as in advanced hydrauic systems of materia handing devices. The QHD2 series covers the range of dispacements from 43 to 150 cm 3 /rev. n The pumps are characterized by simpe construction with hydrauic pressure baance, compact dimensions and a wide range of connection types. QHD2 pumps have a two-piece a-cast-iron construction. The basis consists of a supporting body with a bind chamber for gear whees and a fastening fange. The body, as we as the fange are made from a high-quaity grey cast iron. In the body and the fange, siding seeves for gear whees are moded. Gear whees with 12 teeth made of utra high-strength stee, which are optimised to achieve a ow noise eve. The axia pump baancing is performed using siding auminium aoy pressure pates in which a shape seaing of baancing surface is ocated in grooves. For heavy duty with a weight-bearing drive shaft, the pumps can be equipped with front-end roer bearings. QHD2 construction enabes the pumps to be used aready at ow revoutions at high pressure. n QHD2 pumps are produced in various designs of divers camping fanges as we as iquid inets and outets. These pumps compy with the standards ISO, SAE, UNI and other word-recognised standards and can be deivered in simpe or mutipe designs. They can aso be deivered in a reversibe design, with externa or interna drainage. BASIC PATS OF PUMP 1. Body 2. Fange 3. Driving gear 4. Driven gear 5. Seaing protective pate 6. Baancing seaing 7.

DIECTION OF OTATION n Determine direction of rotation by ooking at the drive shaft. The pump can ony be used in the specified direction of rotation. EVESIBE DESIGN n The pumps with the possibiity of bidirectiona rotation have a different interna arrangement requiring drainage. Two types are used - interna and externa. The interna drainage is aways interconnected with the outet by means of vaves. The externa drainage is soved by an orifice ocated in the cover opposite the driven gear. 6 GPC_QHD2 02 2017 01
