Operation and Maintenance Manual QC Series Centrifugal Pump BEGINNING THE ASSEMBLY It is highly recommended that you resort to the diagram on page 6 to verify the assemblies and subassemblies whose directions will follow. 1. LEG BRACKET ASSEMBLY Sets of leg-brackets are optional and can be used to vertically adjust the pump. The size of the brackets (209) and the legs (207) depend upon the NEMA or IEC of the motor. - Page 11 Operation and Maintenance Manual QC Series Centrifugal Pump The traction between shafts is achieved by friction. By tightening the drive collar bolt (s) (92A), the drive collar plus (92) and the stub shaft (6P or 6E) closes pressing the motor shaft.

Page 12: Assembling And Installing The Mechanical Seal
Operation and Maintenance Manual QC Series Centrifugal Pump 4. ASSEMBLING AND INSTALLING THE MECHANICAL SEAL MECHANICAL SEALS. Among the QC, QC plus, and IC plus pump series there exist five types of mechanical seals. One of these, the “T21”, is used exclusively with our IC+ series, specifically in non-sanitary applications. - Page 13 IMPORTANT: It is necessary to disassemble some of the pump parts for cleaning and sterilizing. For those Q-Pumps products equipped with “D” seals, if a CIP (Clean-in-Place) instillation is used, disassemble is not necessary. Do not lubricate the seal with grease or oil, the faces of the seals are lubricated by the fluid that is being pumped.
- Page 14 Operation and Maintenance Manual QC Series Centrifugal Pump Please remember that the PTFE gaskets (80P) and (80R) are not interchangeable. The seal seat (80N) is made of a very strong material and therefore is very fragile. It is important to protect the faces of the stationary seal just as with the backplate, against bumps and scratches.
- Page 15 Operation and Maintenance Manual QC Series Centrifugal Pump The following instructions assume that the adapter is assembled and that the spacing between the impeller and backplate has been set. If not, we recommend you refer to that section of the assembly directions.
- Page 16 Operation and Maintenance Manual QC Series Centrifugal Pump IMPORTANT: When you mount the backplate onto the adapter, the seal may supply resistance. If this resistance is too much, check the seal assembly and be sure the drive tcollar has been located correctly.
