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,...
