การทำงานของปั๊มโพรงเคลื่อนที่: สิ่งที่คุณต้องรู้

The heart of a progressing cavity pump is built by a rotating Rotorrotor,Rotors,rotorsrotor together with a stator. The rotor is mounted eccentrically and moves in a wave-like path within the elastic stator. The oscillating rotary motion creates chambers moving continuously through the pump, conveying the medium smoothly. This positive displacement pump mechanism allows for gentle pumping, as the medium is not affected by high shear forces or pressure surges. Even with demanding liquids with a high solids content, high gas content or sensitive structure, the quality of the substance conveyed remains unaffected. Progressing cavity pumps are also suitable as submersible pumps in wells and with open-end connections for emptying drums.

Advantages of the progressing cavity pump

The progressing cavity pump's operating principle offers numerous advantages in various industrial applications. The advantages at a glance:

• Constant delivery rate
• High dosing accuracy
• Low pulsation
• Self-priming
• Long service life
• Easy to maintain

The function of the progressing cavity pump enables you to achieve a constant flow rate, which ensures an even fluid flow without interruptions. For you, this means stable processes, fewer rejects and reliable production. Thanks to its high dosing accuracy, it is ideal for precise applications – this ensures exact material addition and reduces losses. The low pulsation also allows you to convey sensitive media gently. Thus, even the most delicate substances are transported without damage. As a self-priming pump, it can efficiently work from great depths or under difficult suction conditions. This means greater flexibility in system planning and reliable pumping, even in challenging situations. The robust design guarantees a long service life, even when pumping abrasive or highly viscous fluids. This reduces the need for frequent replacement investments and ensures higher operational reliability. In addition, the progressing cavity pump impresses with its maintenance-friendly design: Wearing parts can be easily replaced, resulting in minimised downtime and lower operating costs.

Applications of the progressing cavity pump

• 
  Food & Pharmaceuticals
• 
  Environment & Energy
• 
  Mining
• 
  Battery
• 
  Chemical, Pulp & Paper
• 
  Oil & Gas Upstream

Due to their function, progressing cavity pumps are a proven solution for numerous industries and offer reliable, precise and application-optimised conveying. In the chemical, pulp and paper industry, they enable you to precisely dose and safely convey sensitive or aggressive media, thus minimising losses and ensuring stable processes. In the food industry, they are known for their hygienic and gentle pumping of viscous liquids, even those with solid content, which provides consistently high product quality. Progressing cavity pumps also play a crucial role in environmental technology, enabling efficient and smooth sludge pumping in sewage treatment plants while minimising blockages. On the other hand, the advantages of the oil and gas industry are their robust construction and reliable pumping of highly viscous liquids, making them ideal for demanding pumping tasks. With a progressing cavity pump, you benefit from a long-lasting, maintenance-friendly and economical solution optimising your processes.
