Operation and Maintenance Manual
QTS Series Twin Screw Positive Displacement Pump
QTS-M04
Pump Coupled to a Gear-Motor Assembled on
a Base.
This assembly includes a gear-motor with
a coupling, coupling guard and base.
QTS Rotors and Clearances
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.
Using Variable Frequency Drives
The use of variable frequency drives is useful for performing variable applications including the
CIP process using the same pump. By changing the speed of the motor the pump can increase or
decrease the flow to reach different points of operation.
If your equipment is supplied with a variable frequency drive it is as a result of an analysis of the
applications of the pump, please follow the data shown in the Data Sheet.
If you want to use a variable frequency drive after the analysis of the application of the pump,
please contact your distributor or directly to Q-Pumps to be advised about this case. Remember
that using your pump under different conditions than those explained in the Data Sheet may result
in damage to the equipment, personnel and even void your warranty.
