What to Do Before Starting Progressive Cavity Pump?

The same inquiries and debates regarding contracting new progressive cavity pumps as they tend to surface time and again when discussing projects with engineers at fairs and exhibits. PC pumps are frequently designed with features that make maintenance and installation easier. When commissioning a new pump, users may ask what to expect the first time they use a PC pump. Remember the ten items in this article before using the pump for the first time to prevent making many rookie blunders.

Adjust the belts and sheaves- Belt-driven systems can be versatile and dependable, but incorrect installation and maintenance can result in premature belt failure. Incorrect or careless configuration can also have a significant impact on the working life of motors and driven components. Confirm the belt drive arrangement before starting up, as these components may change during shipping or installation. Check that the sheaves are aligned within the pump's tolerance when verifying setup.

Check the wiring and the belt drive tension- Confirm that the electric power leads are wired in accordance with the wiring diagram. This should be confirmed by either the plant's or the contractor's electrician. Finally, validate the pump's rotation with a brief "bump test." Check the belt tension and ensure it is as specified in the owner's manual. Adjust the belt tension as needed.

To avoid short circuit problems-For proper commissioning, general electrical checks should be confirmed. If the fusers or trip points are set too low, it might pose operational risks and problems, while setting them too high can harm electrical system components. 

Ascertain that the needed voltage is present- Consult with the plant or a contract electrician to ensure that the necessary voltage is available. At the motor conduit box, verify the motor leads for operational amp and line voltage. Additionally, ensure that electric circuits are properly safeguarded with adequate fuses, breakers, and time delay settings. When compared to other types of pumps, the starting torque of a PC pump is considerable, but it becomes linear with speed after the initial startup phase. Variable frequency drives (VFDs) are commonly used to power PC pumps. 

Examine the lubricating fluid- Check that the pump is lubricated properly, whether with water or another suitable fluid. PC pumps and components may or may not be packaged and supplied with first-fill lubricants, depending on the manufacturer and design. Grease-lubricated components must be filled, and if water testing is being performed, the suction housing must be filled with process fluid or water. 

Monitor startup- It is recommended that on the first day of a startup, you refer to and apply the provided manufacturer's startup method and checklist to document the pump's performance.

Correctly commissioning a PC pump is essential to many projects since PC pumps are vital to many operations. Following these 7 steps, from opening valves to verifying electrical checkpoints, will help ensure necessary measures are not missed and the process runs smoothly from the start.
