Wie man eine Kreiselpumpe für einen zuverlässigen industriellen Anlauf entlüftet

How to prime a centrifugal pump begins with one practical goal: remove air from the casing and suction line so the impeller starts in liquid, not gas. A centrifugal pump cannot create stable discharge pressure when air occupies the passage where liquid should be. Correct pump priming protects the impeller, mechanical seal, bearings, and suction […]
Auswahl des Ansaugsystems für Kreiselpumpen bei Unterdruck und dampfhaltigen Medien

A centrifugal pump priming system is needed when the pump cannot reliably stay filled with liquid before startup, especially under negative suction, long suction piping, or vapor-prone service. The system removes air or vapor so the pump casing, suction line, and first-stage impeller receive liquid immediately. In industrial plants, priming also prevents dry running, cavitation, […]
BB4- vs. BB5-Pumpe: So wählen Sie die richtige mehrstufige Kreiselpumpe für Hochdruckanwendungen

The main BB4 vs BB5 pump difference is pressure containment: a BB4 is a radially split, segmented multistage pump with one casing, while a BB5 places a multistage inner assembly inside a second barrel-style pressure casing. Neither design is automatically superior. The correct multistage centrifugal pump depends on liquid properties, temperature, pressure, duty profile, containment […]
API 610 BB2 Pumpenauswahl für Hochtemperatur-Petrochemieanwendungen

An API 610 BB2 pump is a strong choice for high-temperature petrochemical service when the duty requires a radially split, between-bearings machine with stable shaft support, controlled thermal growth, and configurable sealing. Selection must still be based on the actual duty point, fluid, suction conditions, materials, and seal arrangement rather than the series limits alone. […]
Ansaugen von Kreiselpumpen: Wichtige Überlegungen im integrierten Raffineriebetrieb

Fundamentals of Centrifugal Pump Operation Core Principles of Centrifugal Pump Mechanics Centrifugal pump operation starts with the motor. The motor turns the impeller. The impeller pushes the liquid outward. This action turns motor power into fluid movement and pressure. The shape of the impeller and the shape of the casing decide how well this change […]
Vergleich der Ansaugmethoden für Kreiselpumpen: Welche Methode eignet sich am besten für Ihr System?

Fundamentals of Centrifugal Pump Priming The Purpose of Priming in Centrifugal Pumps Priming of centrifugal pump is a preparatory process that ensures the pump casing and suction line are completely filled with liquid before operation. This step is essential because air pockets can prevent proper suction formation, leading to vapor locking or loss of discharge […]

Effizienzoptimierung: Axial- vs. Horizontal-Split-Pumpen

In the worldwide water treatment sector which includes industrial desalination, wastewater handling, and major water distribution the centrifugal water pump acts as the key driver of processes.Numerous plants face ongoing troubles: rising energy expenses from inefficient devices, intense shaking that causes mechanical seal breakdowns, and the tough task of intricate upkeep in pressurized setups. These problems usually arise […]
Großartige Neuigkeiten! Das Postdoktoranden-Innovationsprojekt in Longgang hat Fördermittel der Provinz erhalten.

Recently, the review outcomes for the 2026 Shandong Provincial Postdoctoral Innovation Project were announced. Dr. Pan Jiajing, based at the Postdoctoral Innovation Practice Base of Yantai Longgang Pump Industry Co., Ltd., secured a provincial third-class grant on the strength of his project Multi-Field Coupling Optimization Design of Nuclear-Service Liquid Heavy-Metal Pumps and the Mechanism of […]
Die Entscheidungsmatrix: Die Wahl zwischen einer einfach- und einer doppeltansaugenden Pumpe für industrielle Flüssigkeiten

Operational efficiency in petrochemical and refinery environments depends heavily on selecting the correct hydraulic architecture. The financial stakes of this choice are significant, as pump systems often account for a substantial portion of total energy consumption and maintenance expenditures in industrial plants. Understanding the technical nuances within a single-suction and double-suction pump selection process is the first […]
