Real production, precision casting, testing and on site video highlights.
Split case pumps (horizontal double‑suction centrifugal pumps) are engineered for high‑capacity, high‑efficiency fluid transfer. Their horizontally split casing allows full access to the impeller, shaft, and bearings without dismantling suction or discharge piping, dramatically simplifying maintenance and reducing downtime. The double‑suction impeller design inherently balances axial thrust, resulting in smooth operation, low vibration, and extended bearing life.
Our split case pumps are manufactured in large diameters and fabricated from premium stainless steel grades (e.g., 316L, duplex, and super duplex). This material choice delivers outstanding resistance to chloride pitting, crevice corrosion, stress‑corrosion cracking, and erosion from abrasive particles. Stainless steel construction ensures long‑term integrity even in seawater, brackish water, chemically aggressive fluids, and high‑temperature condensate, while also providing hygienic surfaces for potable water applications.
Key advantages include:
High efficiency – typically exceeding 85% at best operating point, reducing energy consumption.
Low NPSH requirements – enabling reliable operation under challenging suction conditions.
Heavy‑duty reliability – designed for continuous 24/7 service with minimal wear.
Easy maintenance – top‑half casing removal grants quick access to internal components.
Corrosion and wear resistance – stainless steel variants withstand aggressive media, extending service life and lowering lifecycle costs.
These pumps are widely deployed in municipal water supply and distribution, agricultural irrigation, seawater desalination plants, cooling water circuits and condensate return systems in power stations and steel mills, as well as in chemical and petrochemical processing. Whether handling clean water, corrosive brines, or high‑temperature industrial fluids, our large‑diameter stainless steel split case pumps offer unmatched durability, efficiency, and operational safety for critical infrastructure worldwide.

LC Vertical Turbine Pumps Casing Pipes
Vertical turbine pumps ( also called line shaft turbine pumps or deep well trubine pumps) feature a surface‑mounted motor connected to a submerged impeller via an extended shaft. They handle deep‑sump applications (depths up to 50 m), high temperatures (≤180 °C), and fluids with moderate solids. Common uses include cooling water circulation, mine dewatering, and chemical sump transfer. Their dry‑motor design and top‑entry maintenance offer high reliability and low downtime.
Vertical mixed flow pumps combine radial and axial action, delivering moderate heads (~18 m per stage) with large flow capacities. They are energy‑efficient and versatile, widely applied in flood control, irrigation, municipal water supply, and industrial circulating systems.
Vertical axial flow pumps excel in low‑head (≤6 m per stage), extremely high‑flow scenarios. Their adjustable blades allow performance tuning, and their compact vertical footprint saves installation costs. They are preferred for agricultural drainage, power‑station cooling, and stormwater management.
Across all three types, stainless steel corrosion‑resistant materials are critical for durability in aggressive environments. Grade 316L provides excellent resistance to chlorides and weak acids, making it ideal for seawater and wastewater. Duplex (2205/2507) offers superior strength and stress‑corrosion resistance, extending service life by up to 2× compared to 316L in saline conditions. Super duplex and alloys like Hastelloy or titanium are used for highly corrosive chemicals and high‑temperature brines. Stainless steel construction ensures pitting‑free operation, low maintenance, hygienic surfaces (for food/pharma), and reliable performance in acidic, alkaline, or marine media. These material choices reduce lifecycle costs and guarantee long‑term pump integrity in the most demanding industrial, marine, and chemical applications.
