7. 5 09 Figure 4 Pump Component Terms 3 0 GENERAL 3 1 CLASSIC PUMPING PRINCIPAL The pumping action of the rotary lobe pump principle is generated by the contra rotation of two pumping elements rotors within a chamber casing see Figure 5 The rotors are located on shafts which in turn are mounted within an external gearbox and supported by the bearings the timing gears are also located on the shafts The timing gears transfer the energy from the drive shaft to the driven shaft synchronizing the rotors such that they rotate without contact with each other As the rotors pass the suction port see Figure 5a the cavity generated increases creating a pressure decrease which induces the pumped medium to flow into the casing The pumped medium is carried around the casing by the rotors see Figure 5b and 5c to the discharge side of the pump Figure 5d Here the cavity decreases and the pumped medium is discharged from the casing Figure 5e For pump component terms see Figure 4 Figure 5 Rotary Lobe Pumping Principle 3 2 CLASSIC RANGE OPERATING PARAMETERS The maximum pressure and speed operating parameters are given in Figure 6 In practice these may be limited due to the nature of the product to be pumped and or design of the system in which the pump is to be installed Consult Viking Pump or your Viking Pump distributor for assistance The operating temperature limit of the pump is determined by the ro
