A volumetric pump is a device that realizes fluid conveying by periodically changing the volume of the pump cavity. Common types include gear pumps, sliding plate pumps, diaphragm pumps, ordinary screw pumps, etc. Although their core logic is volumetric change, the progressive cavity pump, with its continuous and smooth spiral cavity design, is significantly different from the same pump in terms of flow characteristics, media adaptability, anti-blocking ability and operating stability. This article will compare from the five core dimensions and analyze the unique advantages of progressive cavity pumps.

In industries such as chemical engineering and food processing, stainless steel centrifugal pumps serve as "reliable assistants" for liquid transportation. They feature corrosion resistance and wide applicability. However, improper installation can lead to issues ranging from minor seal leaks to major pump vibration failures, affecting production and increasing costs. The following details the installation process from preparation to maintenance.

In chemical production, material transportation is a fundamental yet critical process. Twin-screw chemical pumps are widely used for conveying various liquid media due to their simple structure and stable operation. However, in practical applications, it has been observed that pump performance can vary with changes in the transported materials. Among these factors, viscosity plays a significant role.

Bearings are indispensable components in many mechanical devices, playing a vital role in reducing friction between moving parts. Two common bearing arrangements are Between Bearings (BB, double-supported) and Overhung (OH, cantilevered). These configurations each have distinct characteristics and suit different working conditions. Introduction
