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.

Water pump vibration, noise, pipeline shaking and building resonance are mainly caused by substandard installation and vibration isolation failure. Vibration isolation is a core installation process rather than an optional noise reduction step. Standard installation effectively blocks vibration transmission between pumps, pipelines and building structures, avoiding pipeline cracking and structural resonance, extending pump service life and ensuring stable water supply system operation.

As a professional centrifugal pump brand, Omron Tech Pumps has deep expertise in the industrial fluid transportation sector, with products widely applied across industries including water treatment, chemical engineering, HVAC and manufacturing. Amid upgraded industry energy efficiency standards and continuously evolving production operating conditions in 2026, centrifugal pump selection is no longer a simple matter of parameter matching—it directly impacts equipment energy consumption, operational stability and long-term operating costs. To help enterprises avoid procurement pitfalls, this document concisely outlines ten core selection factors tailored to current industrial procurement requirements.

Transporting strong industrial acid media imposes extremely high requirements on equipment. Ordinary water pumps are prone to corrosion and leakage, posing major safety hazards. Acid pumps are special conveying equipment engineered for heavily corrosive chemical working conditions. They can safely and stably deliver acidic fluids such as sulfuric acid, hydrochloric acid and nitric acid, and are widely applied in industries including chemical engineering, pharmaceuticals, metallurgy and wastewater treatment. These pumps not only ensure stable production, but also eliminate risks of chemical spills and cut operation and maintenance costs. As the chemical industry expands, the global chemical pump market keeps growing, and acid-resistant industrial acid pumps have become core equipment for corrosive fluid handling.

Centrifugal pumps are vital in industrial fluid transport, and slight vibration is normal per ANSI/HI 9.6.4. However, excessive vibration causes severe wear and increased costs. Since vibration is merely a symptom, it typically stems from three overlapping categories: design/selection defects, internal faults, and external system interference. This paper analyzes these core causes to guide equipment inspection and maintenance.

Liquid ring vacuum pumps are common industrial vacuum devices. Using liquid sealing, they create steady vacuum and cope with harsh conditions including high moisture, vapor, mild corrosion and flammable explosive media. They outperform conventional vacuum pumps with reliable performance and low maintenance costs, widely used for vacuum extraction, gas compression and material treatment as key industrial auxiliary gear. This paper briefly introduces their definition, applications, merits, operation principles, models and maintenance guidance.

Magnetic pumps adopt non-contact transmission via magnetic coupling without mechanical shaft seals, achieving zero leakage. They are widely used in chemical and pharmaceutical industries for transporting corrosive and toxic media. Standardized operation can prevent faults such as dry running and bearing damage, extending the service life of equipment by over 30%. Omron Tech Pumps has comprehensively sorted out the core pros and cons, standard procedures and maintenance key points of magnetic pumps, aiming to provide professional reference basis for industrial model selection and daily operation & maintenance.

Calculation of the geometric suction lift Hg of a centrifugal pump is a core procedure in pump installation design. It directly determines whether cavitation will occur, whether the pump can draw water stably, and whether it can operate efficiently for a long time. Many faults such as insufficient water output, loud noise and vibration, impeller damage, and frequent equipment failures essentially stem from miscalculations of the geometric suction lift Hg or excessive installation height.

Sanitary screw pump seals endure prolonged harsh CIP, SIP and acid-alkaline treatment, and wrong material choices trigger seal damage, leakage, contamination and non-compliant production lines. Seal material selection thus needs balanced evaluation of wear, heat and corrosion resistance, sanitary rating and working condition adaptability.

Chemical pumps operate long-term under harsh working conditions involving corrosion, high temperatures, and high impurity content. Reliance on ingrained experience during routine maintenance can easily lead to repair misconceptions. These not only fail to eliminate faults fundamentally but also accelerate equipment wear and create potential safety hazards.
