1 s 40 to 100 Gear ump Model G4, Series 2X 3000 SI (210 bar) 6.1 in 3 (100 cm 3 ) / /03.95 eplaces: SE connection flanges Sleeve bearings for long life Single block bearings ISO or SE drive shaft and mounting flange Tandem pumps possible Hydraulic pumps, model G4, are self-priming, external gear pumps. pplicable to 3000 SI (210 bar), these fixed displacement pumps provide flow to operate hydraulic circuits. Consisting of housing (1), mounting flange (2), drive shaft (3), bearing blocks (4), sleeve bearings (5), and rear cover (6). G4 series gear pumps are designed to handle the rigors of industrial use. otation of the gears creates a void at the suction inlet (S). Fluid trapped in the gear roots is transported to the pressure port (). This merging of fluid creates flow, which reflects a pressure signal as a result of load forces. s evident by the cross-section, any void created at the suction inlet will immediately be replaced by reservoir fluid. To enhance smooth performance, a small volume of load-pressurized-fluid is needed to aid in internal lubrication /29 Model 1 F 2 G4-2X/...E 07 MC Symbol S 3 S Technical data (For operation outside these parameters, please consult us!)

General data for single pumps is also applicable to double pumps (see page 1) The following should be given particular attention in double pumps: ump I must consume higher power (pressure x flow) than pump II. ump I and pump II are not separated on the suction side. The torque transmitted by the drive shafts and the coupling between the pumps is limited as shown below. When applying double pumps, the sum of the torques must not exceed permissible values. Drive torque T lb-ft (Nm) (300) (250) (200) (150) (100) ermissible torques on shaft end = 25 mm dia. parallel shaft T max = 185 lb-ft (250 Nm) H = Coupling between pump I and pump II T max = 370 lb-ft (500 Nm) (100) (150) (200) (250) ressure p SI (bar) 5
