TEFFIKO Heavy-Duty Industrial Pump

In the petrochemical industry, magnetic pumps have become one of the key equipment for ensuring safe and efficient production due to their advantages such as leak-free operation and strong corrosion resistance. With the continuous advancement of industrial technology and the steady growth of market demand, numerous magnetic pump brands have stood out in the petrochemical sector. Today, we introduce the top 10 global magnetic pump brands in the petrochemical industry.

Split casing pumps (split case pumps, split casing centrifugal pumps) are core fluid transportation equipment for industrial and civil applications. Featuring splittable pump casings, large flow rates, high stability and easy maintenance, they are widely adopted in municipal engineering, fire protection, heating ventilation and air conditioning (HVAC), power generation, chemical industry, agriculture and other sectors, serving as the preferred pump type for 24-hour continuous water conveyance conditions. This guide systematically sorts out core knowledge of split casing pumps to facilitate rapid model selection, standardized operation and maintenance.

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 the field of fluid transfer in modern industry, traditional centrifugal pumps often struggle when handling complex media such as high-viscosity fluids, particle-laden fluids, and even gas-liquid mixtures, while screw pumps frequently suffer from high maintenance costs. As a positive displacement pump, the cam rotor pump has been widely adopted across various industries to address pain points in fluid transfer. With its unique advantages, it has become the preferred choice for an increasing number of enterprises.

As a representative of positive displacement pumps, screw pumps are widely used in industries such as petroleum and chemical engineering due to their compact structure, stable operation, and adaptability to complex media. They particularly excel in conveying high-viscosity fluids, particle-laden media, or shear-sensitive materials. However, in practical applications, improper selection often leads to issues such as low efficiency, increased energy consumption, and frequent failures, primarily because users focus only on basic parameters like flow rate and head while neglecting medium characteristics, operating conditions, and long-term costs. This article analyzes common selection misconceptions and provides systematic, science-based methods to help users accurately match equipment needs and enhance the overall efficiency and economy of pumping systems.
