GEAR PUMPS “PG” SERIES GEAR MOTORS “MG” SERIES P3 = Peak pressure P2 = Intermittent operating pressure (1/3 of working time) P1 = Continuous operating pressure max. 20 s GENERAL Superior performance and reliability in heavy-duty hydraulic application. Construction with large area, low-friction bushings provide strength, high efficiency, and long life in severe operating environments. The design includes an advanced thrust plate and seal configuration,which optimizes performance even in high temperature and low viscosity conditions. Double pump with common suction reduces mounting costs, allow for a small package size. WORKING CONDITIONS - Pump inlet pressure (absolute pressure) - Minimum operating fluid viscosity 1 - Suggested fluid viscosity range - Fluid operating temperature range - Fluid operating temperature range with FPM seals(Viton) - Hydraulic fluid Important: in case of assembling of pumps without shaft seals, you have to keep the value of min. suction pressure ( 0.7 bar (abs)) in the vane between pump and coupling too. Lower pressure can lead to suction of oil through the front flange (seat of the shaft without seal); this can damage seriously the pump. 1 - With reduction 80% of working pressure and at minimun speed. Suggestion: to have the best behaviour and duty life of the pump/motor, use a cooling system in order to keep the uid temperature at 60°C and viscosity at 20 cSt.In addition to the recommended ltration index of page 3.

DRIVE SHAFTS Radial and axial loads on the shafts must be avoided since they reduce the life of the unit. DIRECTION VIEWED AT THE DRIVE SHAFT Pump PUMP Pump PUMP Bi - directional rotation Outlet PUMP MOTOR MOTOR Motor MOTOR Motor In case of need we can supply the flange with a threaded hole to vent the drain of the shaft seals area. As you can see on pages 10 and 11, the flanges are: S7 with G1/8 threaded hole S8 with SAE4 threaded hole HYDRAULIC PIPE LINE To ensure favorable suction conditions it is important to keep pressure drop in suction pipe line to a minimum value (see WORKING CONDITIONS)....

If necessary, you can put a mark which help you remembering the position of the plate related to the body.This is very important, because at the end you must reassemble it in this way. take off the thrust plate. Step 5: take off both the shafts, drive and driven. reverse their position and re-assemble them. reverse and reassemble the front ange. re-assemble the...
