Page 11: Spacing Of The Impeller And Stub Shaft
OPERATION AND MAINTENANCE MANUAL TR-IS SERIES Centrifugal Pump 3. SPACING OF THE IMPELLER AND STUB SHAFT The correct operation of the pump depends on the separation of the impeller (5) from the backplate (7), and the fixation of the stub shaft (10) on the motor shaft. Follow the ensuing steps to install the stub shaft on to the motor shaft. - Page 12 OPERATION AND MAINTENANCE MANUAL TR-IS SERIES Centrifugal Pump Figure E Place only the rotary holder of the mechanical seal (6A) together with its respective O-ring (6H) until it seats on the shoulder of the stub shaft. Put the impeller key (12) on the keyway of the stub shaft.
- Page 13 OPERATION AND MAINTENANCE MANUAL TR-IS SERIES Centrifugal Pump Once the assembly is tightened, place a spacer between the back of the impeller and the front of the backplate. Use a spacer of 0.025” (0.63 mm) thru 0.030” (0.76 mm) for models 114, 214, 216 &...

OPERATION AND MAINTENANCE MANUAL TR-IS SERIES Centrifugal Pump Tighten the assembly as it is indicated in step 3c. For models 114 and 214 use a torque value of 25 ft.lb. For all other models, use a torque value of 40 ft.lb. Figure M. - Page 17 OPERATION AND MAINTENANCE MANUAL TR-IS SERIES Centrifugal Pump Place the stationary face of the mechanical seal (6C) with its O-rings (6J & 6K) into the backplate seal housing. First, place the O-ring (6J) on the stationary face groove, then the O-ring (6K) on the back.
- Page 18 OPERATION AND MAINTENANCE MANUAL TR-IS SERIES Centrifugal Pump Now, insert the whole rotary seal sub-assembly on to the stub-shaft. This will contact the stationary seal face previously placed in the backplate. Push to compress the assembly and then insert the impeller key into the stub-shaft. Place the O-ring (6G) onto the stub-shaft end; this O- ring seals between the stub-shaft, the rotary holder, and impeller.
- Page 19 OPERATION AND MAINTENANCE MANUAL TR-IS SERIES Centrifugal Pump Finally, place the racor flushes (9) on to the backplate; one on top and one at the bottom. It is recommended to feed clean water to the double mechanical seal with a pressure of 10 to 15 psi maximum.
