Page 2: General Description
Model C2E and C2F pumps are sleeve bushing lip seal units designed for direct drive service. Model C2E comes with the foot assembled to the pump. Model C2F is a flange mount pump. Model C2FA pumps are similar to model C2F but are supplied without a seal. Model C2EN pumps are sleeve and ball bearing units with a lip seal and mounting foot designed for indirect (belt, chain, gear) drive. - Page 3 These pumps should not be used for handling plain water, corrosive or abrasive liquids or liquids not possessing adequate lubricity. Do not attempt to work on any Tuthill pump installation before completing the steps below. Disconnect the drive so that it cannot be started while work is being performed.

Page 4: Proper Installation
Most Tuthill C Series pumps are required to develop 25" mercury vacuum at 0 psi on factory test. While these pumps will develop as high as 27" of vacuum, it is a sound engineering practice to avoid extreme vacuum whenever possible. Select a pipe size to reduce line friction loss to a minimum. - Page 5 All pump and motor units must be properly aligned during assembly and periodically checked since misalignment may occur later due to abuse or other conditions. Pipe strain can force the pump and motor shafts out of alignment. Therefore, all piping to the pump must be properly supported.
- Page 6 WARNING WARNING All Tuthill pumps contain residual 200 SSU lube oil from the factory test. Determine if this is compatible with the fluid you are pumping. If the fluid is incompatible, consult the factory. If the pump is to operate at elevated temperatures, it should be brought up to operating temperature gradually.

Page 12: Changing Rotation
If outfitted with an internal relief valve (model CK1BV), the rotation cannot be changed in the field unless the cover/valve assembly is also replaced. To change the location of the suction port on pumps supplied with Tuthill's unique automatic reversing feature (model RCK1B), the following must be done in addition to the steps above: •... - Page 13 Inspection: • Check the pump housing, rotor, idler gear, idler pin and cover for wear and chipped or broken teeth. There must not be any deep scratches or grooves on the following: ID surface of the housing OD of the rotor End face of the rotor OD of the idler Either face of the idler...
- Page 14 Vent all pressure within the pump through the suction or discharge lines. All Tuthill pump contain residual 200 SSU lube oil from the factory production test. Determine if this is compatible with the fluid you are pumping. If the fluid is incompatible, consult the factory.

Page 15: Troubleshooting
• Align the matching marks for proper location. • Install the cover screws. Tighten gradually, alternating from a screw on one side to a screw on the opposite side. • Install the packing or seal, following the instructions for the specific model in question. Troubleshooting No fluid is delivered: •... - Page 16 RGA can be issued until a completed Material Safety Data Sheet (MSDS) has been forwarded to our Chicago plant and return of the pump approved. • Tuthill pumps are precision built and must be handled with care. • Pumps must be drained of all fluid and the ports plugged to prevent foreign material from getting into the pump.
