Save time and money by checking adjustment in the time frame or differential pressure set points before start-up. they typically will not meet Teikoku’s pressure and time delay rec- ommendations. Attention! The preferred method to monitor the input power to the pump would be to use a power monitor like the Load Controls PMP-25. -

Page 24: Appx. A. Trc-1 Information Sheet
The design of canned motor pumps is such that the rotating element cannot be seen while it is in operation. For this reason, Teikoku supplies an internal rotation indicator with a majority of our pumps. However, there are some instances where this device is not supplied, so we recommend purchasing the TRC-1. -

Page 34: Appx. K. Decontamination Certification And Flushing Procedure
Attach completed material safety data sheets (MSDS) for these fluids. If either fluid is proprietary, please attach a description of any characteristics that will assist Teikoku USA in safe handling. Without detailed and complete information on the pumped fluid, we will not be able to process your order. - Page 35 For pumps with shaft sleeves, complete disassembly will be required to remove trapped fluid. Flush all auxiliary tubing, piping and equipment such as heat exchangers. For any questions on decontamination, contact your Teikoku service representative. See sections "B" through "D" for stator assembly decontamination requirements where a liner breach is suspected.
- Page 36 If the connection box is to be returned, assure that all components have been decontaminated. D. For all Teikoku pumps, LE stators, G and NC stators with TRG. If a stator liner rupture is suspected, follow this section to flush the stator cavity. Caution: if this step is followed, the motor must be rewound.

Page 37: Appx. L. Repair Receipt Policy
Teikoku USA policy requires that an RMA be generated prior to the shipment of pumps or components to any Teikoku USA facility. With the shipment Teikoku USA also requires a copy of the RMA, a completed Teikoku USA Decontamination Form, an SDS for the process fluid to which the pumps or parts were subjected and an SDS on the decontamination flush fluid that was used to decontaminate the equipment. - Page 38 www.teikokupumps.com Pennsylvania Texas Ohio 959 Mearns Road 5880 Bingle Road 27881 State Route 7 Warminster PA 18974 Houston, TX 77092 Marietta, OH 45750 215-343-6000 713-983-9901 740-538-5332 NCT-A50-8-N3-25S 0620...
