10. Gear case cover Pump Arrangements Assemblies The QTS series pumps can be delivered coupled to a drive element in different ways to solve one specific application. They can be ordered and delivered as follows: Pump Only. In this case the pump is supplied with a drive shaft for coupling, does not include motor/gear-motor, coupling or base.
The design of QTS rotors (twin screws) in addition to the clearances kept with the casing, allow pumping high viscosity fluids without the risk of contact between them. The secret of the correct operation of the pump it’s on the proper rotor synchronization. Please contact Q-Pumps to discuss this topic.
QTS Series Twin Screw Positive Displacement Pump BASE ALIGNMENT Pump / base assemblies are aligned in Q-Pumps factory prior to shipment. However assembles must be checked prior operation to avoid any misalignment. Misalignment may cause unneces- sary wear and shorten the life of the pump. You can notice misalignment with excess noise and vibrations.
