Jiachuang Metals enclosed best wishes for Christmas day and new year.

Discover why petrochemical and coal chemical industries rely on Dalian Jiachuang’s alloy steel sand casting guide vanes. Featuring Duplex Stainless Steel and Nickel-based alloys for corrosive, high-flow environments.

From thermal power to nuclear and hydro-power generation, the efficiency of fluid machinery is important. At the heart of these systems lie the pumps—specifically, multistage centrifugal pumps designed for high flow and high head applications. The performance of these pumps is not just determined by the motor, but critically by the hydraulic components inside, with the casting guide vane body playing a decisive role in energy conversion.

In the high-stakes world of industrial fluid handling, the turbopump is often the heart of the operation. Whether in a desalination plant fighting seawater corrosion or a petrochemical facility moving volatile fluids, the efficiency of these pumps relies heavily on their internal hydraulic components. The Casting Turbine Pump Guide Vane also plays a pivotal role.

In bioprocessing applications requiring strict sterility and stable flow control, Jiachuang’s wear-resistant sand casting pump covers made from stainless steel and cast steel offer a dependable solution. With high strength, corrosion resistance, and reliable sealing, they support continuous operation, withstand pressure fluctuations, and meet CIP/SIP requirements, making them suitable for fermentation, pharmaceutical intermediates, and other sensitive bioprocess fluid transfers.

Cast steel sand casting pump bodies are ideal for fine chemical fluid transfer, where corrosive media, high purity requirements, and long-term continuous operation are critical. Compared with cast iron or non-metallic materials, they offer higher structural strength, better impact resistance, and stronger adaptability to acidic and alkaline media through flexible alloy selection. With stable performance under high pressure and heavy loads, these pump bodies help extend service life, reduce maintenance, and ensure safe, reliable operation across fine chemical, petroleum, metallurgical, and power industry applications.

In industrial pumps, the impeller is the core component that drives fluid flow, and its quality directly affects the pump's efficiency and service life.

What are the common materials for Casting impeller? Based on the actual application and operating conditions, the common materials for impellers mainly include

For clean liquids, the Closed Impeller is the undisputed king of hydraulic efficiency. However, efficiency is context-dependent. Discover why specific speed, clearance, and fluid type determine your system's true energy performance.

• Process analysis: Our engineers will analyze the structure of the pump casing based on the drawings to determine the parting surface (the location where the mold opens), the gating system (the channel through which the molten metal flows), and the risers (used for feeding and preventing shrinkage cavities). • Pattern making: A "pattern" of the casting pump casing is made according to the design. The material is usually wood (for single pieces or small batches), resin, or metal (aluminum/steel, for large batches). • Core box making: The inside of the casting pump casing is hollow and has a complex shape (such as the impeller chamber and inlet/outlet flow channels), making direct demolding impossible. Therefore, sand cores must be made. The core box is the mold used to make these sand cores.
