TR-C Series Centrifugal Pump IMPORTANT SAFETY INFORMATION Safety is very important! DO NOT attempt to modify any Wright Flow product, the TR-C series centrifugal pumps have been designed to be safe and reliable. Modifying them could create unsafe conditions and void all warranties. -
Page 5: Installation
Before servicing pump, disconnect the electrical power source. The TR-C series closed-coupled pumps are made up of two sections: power or drive section and the liquid end or pump section. The pump is mounted to the frame of the drive motor by means of an adapter and is coupled to the motor shaft. -

Page 10: Assembly
Installation, Operation & Maintenance Manual TR-C 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 motor. - Page 11 Installation, Operation & Maintenance Manual TR-C 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. To have an optimum performance, it is necessary to align the three groups of the assembly: 1.-...

Page 12: Assembling And Installing The Mechanical Seal
Installation, Operation & Maintenance Manual TR-C Series Centrifugal Pump 4. ASSEMBLING AND INSTALLING THE MECHANICAL SEAL MECHANICAL SEALS. Among the TR-C, TR-C 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 Installation, Operation & Maintenance Manual TR-C Series Centrifugal Pump The seal will provide a resistance when it slides on, so apply pressure until it has gone onto the stub shaft completely. The position of the drive collar against the o-ring and carbon is critical to prevent leaks.
- Page 14 Installation, Operation & Maintenance Manual TR-C 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 Installation, Operation & Maintenance Manual TR-C 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 Installation, Operation & Maintenance Manual TR-C 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 collar has been located correctly. The efficiency of the “E” seal relies on the proper installation of the drive collar.

Page 17: Kit Plus Assembly
Figure B. We can easily convert a TR-C series standard pump to a TR-C plus series pump with a Kit plus. The TR-C plus series is 100% sanitary and meets the sanitary regulations set by 3A. The TR-C plus series uses an improved design that maintains a tighter, more sturdy assembly. -
Page 18: Industrial T21 Seal Assembly -Ic+ Series
An IC plus series pump is composed of the same parts as a standard TR-C series pump, but requires the plus Kit to set the stub shaft and install the impeller. It also uses an industrial internal seal – T21 – and a specially designed backplate. The T21 seal generally comes as a Kit and is disposable, so if one of the parts is damaged you need to replace the entire Kit. -
Page 19: General Assembly Inspection
Installation, Operation & Maintenance Manual TR-C Series Centrifugal Pump 7. GENERAL ASSEMBLY INSPECTION WARNING Before inspecting your pump’s assembly, double-check that the electric supply is disconnected, and that there is no supply of pressure or fluid into the piping. Before continuing, please check that all bolts/screws and set screws have been tightened. -
