1. Align belt and pulley. Belt drives are versatile and reliable, but incorrect setup and maintenance practices can lead to premature belt failure. Inaccurate or negligent configuration can also have a serious impact on the service life of the motor and drive components. Confirm belt drive Settings before starting, as these parts may move during transportation or installation. When verifying the setting, check that the pulley is aligned within the pump's tolerance.

2. Confirm the wiring and belt drive tension. Check that power cables are connected according to the wiring diagram. This should also be verified by the plant's electrician or the contractor's electrician. Finally, the rotation of the pump is confirmed by a brief "ventilation test". Check the belt tension and confirm that it is as described in the operating manual. Adjust belt tension if needed.

3, prevent short circuit problems. General electrical checkpoints should be verified for proper commissioning. If the fixer or trip point is set too low, it may cause operational risks and problems, while if it is set too high, it may damage electrical system components. It is highly recommended that the factory electrician be present with the control supplier during this verification process.

4, ensure the required voltage. Work with a factory or contract electrician to ensure the required voltage is provided. The motor leads for the operating amplifier and line voltage should be checked at the motor junction box. In addition, verify that the circuit is properly protected with sufficient fuses, circuit breakers, and appropriate delay Settings. Compared to other types of pumps, PC pumps have a high starting torque and then a linear relationship with speed after the initial starting phase. PC pumps are usually driven by variable frequency drives (VFDS). Always consult a VFD expert to adjust the parameters correctly.

5. Check the seal. For packing seal: Tighten the packing or sealing gland nut. Be sure to tighten the packing gland nut by hand and check for leaks. When tightening, tighten in very small increments and allow time for adjustment. Keep in mind that packing seals are designed to leak at a small rate. This minimal leakage helps cool and lubricate shafts and worn parts. Install packing or seal lubrication. Confirm or reconfirm that the packing is compatible with the process fluid. Verify the type of packing and the correct installation of packing or seal lubrication according to drawings provided by the manufacturer. If necessary, follow the manufacturer's recommended lubricating filler. For mechanical seals: Check alignment. Carefully check the alignment of the mechanical seals and ensure that all fasteners are fully tightened to the correct specifications. Installation AIDS, such as alignment clips, strips, or spacers, should be placed in the "operate" position. If you are using a lubricating mechanical seal, confirm the fluid type and level. The configuration of mechanical seal lubrication or pressurization systems varies greatly. If available, consult the manufacturer's installation, start-up, and operating instructions.

6. Locate the coupling and belt guard. Since safety guards are often removed during installation, make sure that all safety guards are secured in place. These guards prevent anything from getting caught in the fast-moving rotating shaft. If you have any concerns about protection, consult your local safety regulations or equipment manufacturer.

7. Install drainage plugs. During transportation and storage, discharge plugs may be loosely transported to prevent any moisture intrusion. Verify that these drain plugs or check caps are fully installed, and then ensure that there is liquid in the pump when starting up to help fill the system.

8. Check the lubricant. Verify that there is proper lubrication in the pump, whether it is water or another appropriate liquid. Depending on the manufacturer and configuration, PC pumps and components may or may not be shipped and supplied with first-fill lubricants. Items that need to be filled for grease lubrication, if water testing is performed, the suction housing should be filled with process fluid or water. After confirming the presence of lubricant, check the oil level in the drive gearbox, as some gearboxes may be shipped from the manufacturer while others are not.

9. Open inlet and discharge valves. Pipeline protection is essential because failure due to an unopened valve is a typical feature of any positive displacement pump. Closing valves or other line obstructions in upstream or downstream lines of pumps may cause problems in the pump or piping system

Catastrophic failure. To ensure a smooth process, make sure all valves in the inlet and outlet lines connected to the pump are open.

10. Start monitoring. On the first day of start-up, reference and use of the provided manufacturer start-up procedures and checklists are encouraged to record pump performance.
