Assembly and installation manual QIM/QDB Mixer Series 3. SPACING OF THE IMPELLER AND STUB SHAFT The correct functioning of the pump depends on the separation of the impeller (2S) from the backplate (11A) and the fixation of the stub shaft (6P) on the motor shaft. Follow the next steps to fix the stub shaft on the motor shaft: 3a.

Once the assembly is tightened place a spacer of 0.060” (1.53 mm) thru 0.070” (1.78 mm) between the back of the impeller and the front of the backplate. You may use a caliper, some shims or a washer with that width to set the critical distance for the correct performance of the mechanical seal.
Assembly and installation manual QIM/QDB Mixer Series 3e. Using the 3/8” rod and the hexagonal socket and wrench to untighten the impeller nut to remove the elements previously assembled.

Assembly and installation manual QIM/QDB Mixer Series Place and fix the backplate with the stationary seal into the adapter, as in step 3b. 4b. Assembly the rotary single seal face (96B), the rotary seal O-ring (96G), spring (96D) and rotary holder O-ring (96E) into the rotary holder (96A). Remember that you can use water or dishes soap to lubricate or glue O-rings and gaskets to the metal elements to facilitate assembly.
Assembly and installation manual QIM/QDB Mixer Series Tight the assembly as previously did before in step 3c. For models 114 and 214 use a torque of 25 ft.lb and a torque of 40 ft.lb for the rest of the models when tightening the impeller nut.

Assembly and installation manual QIM/QDB Mixer Series 6e. Continue mounting the hopper on the tabs at the sides of the poles of the table. Use the hexagonal screws (T3) and nuts (T4) to maintain in position the hopper but do not tight them yet so you can lift the hopper to install the ball valve (V).

Assembly and installation manual QIM/QDB Mixer Series Notes. Before starting the pump check that the motor turns in a counterclockwise direction. Keep the suction line flooded and the mechanical seal lubricated with the fluid which is going to be pumped. Never operate the pump when dry or it may damage the seal. Maintain enough NPSH available in the suction line to avoid the pump to cavitate.
