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.

Top 5 Applications of Spent Wash Transfer Pumps You Should Know

  Every drop of spent wash—the dense, high-temperature by-product of ethanol and sugar production—tells a story of complex industrial movement. Behind the scenes, powerful pumps shoulder the burden of transporting this heavy, often corrosive liquid without clogging, stalling, or giving in to wear. And at the heart of this operation lies the spent wash transfer pump —an essential component of efficient and sustainable industrial processing.   Used extensively across distilleries and agro -based industries, spent wash pumps play a pivotal role in maintaining flow consistency and preventing environmental damage. But their utility extends far beyond just moving liquid. Designed using positive displacement pump princi ples , these machines are built to handle the most demanding fluid transfer tasks.   In this blog, we dive into the top 5 applications of spent wash transfer pumps —so you can better understand their significance, and why choosing the right one is critical fo...

Benefits of Using Magma Massecuite Pumps in Sugar Industry

The course of sugar production starts with the arrangement of cane for juice extraction. Stick is cleaned by spreading it into disturbing transports and going through planes of warm water, clearing off leaves, soil, and rock particles. Beetroot is hacked before juice extraction. The course of juice extraction includes cutting, destroying, and pressing cane and beet with the assistance of roller factories. The separated juice is a dull green, dinky acidic fluid requiring bubbling for additional handling. Lingering bagasse is shipped off boilers for use as fuel for power age. This cane juice is treated with intensity and milk of lime to remove acidity. The treated juice is then additionally warmed and shipped off for sedimentary cleaning. The clear juice is dissipated to a syrup stage, branched by sulfur dioxide then, shipped off vacuum prospects focus and sugar grain development. Crystals are created to the ideal size and the solidified mass is then dropped in crystallizers to deplete...

Why Screw Pumps Are the Best Choice for Industrial Applications

  When it comes to industrial applications, pumps are the unsung heroes. They're the workhorses keeping everything flowing, and a pump failure can grind entire operation to a halt. That's why choosing the right pump technology is crucial. And if you're looking for reliability, efficiency, and versatility, it's hard to beat the performance of a screw pump. But why are screw pumps so often favored? Let's delve into the reasons explaining why these pumps are a top choice, especially when you're considering options from leading industrial pump manufacturers like Risansi Industries. Gentle Pumping Action for Delicate Materials One of the key advantages of screw pumps is their gentle pumping action. Unlike centrifugal pumps that use high speeds and impellers, screw pumps rely on the rotating motion of one or more screws to move fluid. This creates a smooth, continuous flow with minimal shearing force. This gentleness is particularly valuable when handling sen...
