OEM vs. Aftermarket Progressing Cavity Pump Parts: A Practical Comparison for Industrial Efficiency

In industries where fluid handling is mission-critical—such as wastewater treatment, oil and gas, food processing , and mining —the performance and longevity of progressing cavity (PC) pumps directly impact operational efficiency. Pumps from brands like Moyno® , Seepex®, and Netzsch® are known for quality, but when it comes to sourcing replacement parts, many professionals are now weighing the cost, speed, and reliability of aftermarket components over OEM originals. Key Components of a Progressing Cavity Pump Progressing cavity pumps rely on a helical rotor rotating within a rubber stator to move fluid consistently and gently. Core wear components include: Rotors – Often chrome-plated or hardened for abrasion resistance Stators – Made from chemical-resistant elastomers like NBR, EPDM, or HNBR Drive components – Including shafts, couplings, and seals Because these parts experience constant wear, efficient and economical replacement is essential. The Value of Aft...

Centrifugal Pumps in the Pulp and Paper Industry: A Comprehensive Overview

Image
The pulp and paper industry is one of the most demanding sectors for fluid handling equipment. Among the most critical components supporting this industry are centrifugal pumps. Their ability to handle a wide range of fluids, including slurries, chemicals, and wastewater, makes them indispensable to the pulp and paper production process. Centrifugal pumps operate by converting rotational energy, typically from an electric motor or engine, into kinetic energy that moves fluid through a system. This movement is achieved using an impeller, which spins to create centrifugal force, pushing liquid outward and into the discharge piping. In the context of pulp and paper manufacturing, centrifugal pumps are used throughout nearly every stage, from raw material preparation to final product finishing. In the initial stages of pulp production, centrifugal pumps are employed to move wood chips, chemical pulping liquors, and water. The wood preparation process, which includes debarking and chipping,...

Pumping Shear-Sensitive Fluids with Progressive Cavity Pumps: A Practical Guide

Image
  When it comes to pumping shear-sensitive fluids, selecting the right type of pump is crucial. Progressive cavity pumps (PCPs) are often the preferred choice due to their gentle handling characteristics, excellent control, and precise flow rates. Understanding why these pumps excel in handling delicate fluids and how to best operate them will ensure efficiency and reliability in your processes. Understanding Shear-Sensitive Fluids Shear-sensitive fluids are substances whose properties—such as viscosity, molecular structure, or consistency—change adversely when subjected to shear forces. Examples include adhesives, polymers, emulsions, food products like yogurt or cream, slurries, and pharmaceuticals. The integrity of such fluids can degrade significantly when subjected to excessive agitation or shear, potentially ruining the end product or compromising performance. Why Progressive Cavity Pumps? Progressive cavity pumps feature a unique design: a helical rotor turning eccentr...

Progressive Cavity Pumps in the Wine Industry: ACCA’s Solution for Efficient and Gentle Wine Transfer

Image
In the wine industry, precision and product care are vital at every step. From grape harvest to bottling, maintaining flavor, aroma, and structure is key—especially when producing premium wines. The tools and equipment used in production must support these goals, especially during fluid and semi-solid transfers. ACCA Progressive Cavity Pumps provide a top-tier solution for wineries, offering gentle wine transfer , durability, and efficiency. What Are Progressive Cavity Pumps and Why Are They Ideal for Wineries? Progressive cavity pumps are designed to move viscous, abrasive, or solid-laden fluids with minimal shear. They use a helical rotor inside a double-helix stator to form moving cavities that push the product forward in a smooth, consistent flow. This pumping action makes them ideal for delicate products like wine must, lees, and pomace. Compared to other winery pump solutions, progressive cavity pumps offer: Low-shear transfer , preserving wine quality Steady flow without puls...

Progressive Cavity Pumps in the Pulp and Paper Industry: A Comprehensive Analysis

Image
  The pulp and paper industry is a highly demanding sector that requires efficient and robust pumping solutions to handle a wide variety of fluids, ranging from raw pulp slurries to wastewater treatment. Among the many types of industrial pumps used in paper mills, progressive cavity pumps (PCPs) stand out for their ability to handle high-viscosity, abrasive, and shear-sensitive materials with remarkable precision. In this article, we will take a deep dive into progressive cavity pumps , exploring their mechanism, advantages, disadvantages, applications, and comparisons with other pump types such as lobe pumps and gear pumps . Understanding Progressive Cavity Pumps How Do Progressive Cavity Pumps Work? A progressive cavity pump (PCP) is a positive displacement pump that moves fluid through a series of small, fixed cavities formed by a rotating helical rotor inside a flexible stator . As the rotor turns, these cavities progress along the length of the pump, creating a c...
