3 DESCIPTION n series pumps based construct and the displacement range of series pumps is based on the proven UC (UN) series. The cover and flange are manufactured from grey iron. The body is designed from aluminum alloy shaped profile bars. Pumps are connected with four through-bolts made of M12 high strength steel. They are equipped with a hydraulic pressure compensation axial-clearance which is executed by means of a balancing sealing directly in the bearing sleeves. Compared to the previous design of UC (UN), the series pumps have better noise, maximum pressure and flow efficiency within the entire speed range, whereas the favorable price has been maintained. series offers a possibility large range displacement Vg = 5 to 39 cm 3 /rev, at achieve nominal pressure up to 30 MPa. They are produced in unidirectional and in multiple versions. n Pumps of series can be equipped with flow regulation and a relief valve (see. page 9-12), both in the unidirectional and multiple version (see. page 24).

4 n A reinforced version (D), or a shortened version (K) can be used for special purposes n D pumps are a reinforced version that is about 10 mm longer. The Pump has increased the pressure from displacement >16 cm 3 /rev. The position of the inlets and outlets is shifted by about 5 mm on body and about 10 mm on the cover compared with the standard version. n K pumps are about 11.4 mm shorter. The position of the inlets and outlets is shifted by about 5.7 mm on body and 11.4 mm on the cover compared with the standard version. PAAMETE TABE Nominal Size Parameters Sym. Unit.

OTHE EQUIEMENTS n Technical requirements for multiple pumps are the same as for single version pumps.

7 DIECTION OF OTATION n Determine direction of rotation by looking at the drive shaft. The pump can only be used in the specified direction of rotation. OTHE EQUIEMENTS n Technical requirements for multiple pumps are the same as for single version pumps. In case of multiple pumps the maximum torque, which transfer clutch between each sections, is 110 Nm. Therefore, caution should be used while burdening more sections at once (see allowable torques on the output shaft and the clutch). Section 1 should be burdened by the product of pressure and flow more than section 2 6 GPC_

EVESIBE DESIGN n Pumps with the possibility of bidirectional rotation have a different internal arrangement requiring drainage. Two types of drain are used - internal and external.

9 EVESIBE DESIGN n 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 fig.). Maximum pressure in the drainage of the serial version (standard seal shaft) is 0.5 bar. 8 GPC_

10 PUMP WITH FONT-END BEAING Without front-end bearing the driven unit must not impart axial or radial load of the driven shaft once the engine has been connected to it! FOW EGUATO FO UNIDIECTIONA PUMP n The pump may be equipped with liquid flow regulator, which is designed to maintain constant flow rate regardless of the pump PM. This principle can be used everywhere, where there is a requirement for motion control at constant speed regardless of PM. The value of flow rate is determined by type of aperture (see the following figures). Three way flow control valve Excess flow returned to suction line Q konst = 2-30 l/min Three way flow control valve with pressure-relief valve Excess flow returned to suction line Q konst = 2-30 l/min, p 1 = bar Pressure-relief valve Discharge returned to suction line p 1 = bar Note: The setting values of the safety valve must be consulted with the producer.
