Horizontal Loop Reactor Axial Chemical Flow Pump
The Horizontal Loop Reactor Axial Chemical Flow Pump is engineered to deliver stable, large-volume circulation for polypropylene (PP), polyethylene (PE), LAO, and PAO production units. With more than a decade of continuous development, Haishi Pump has achieved full product coverage for 100,000–600,000 tons/year polyolefin loop reactors, becoming a trusted supplier in the global chemical and petrochemical market.
Product Overview
The horizontal loop reactor axial chemical flow pump-also known as an elbow pump or propeller pump-is designed for high-flow, low-head industrial applications.
Haishi provides a full series of axial flow pumps engineered for harsh operating environments, delivering excellent hydraulic performance and outstanding stability in polymerization slurry circulation.
The pump and motor are flexibly coupled and mounted on a common baseplate for smooth and reliable operation.
Key Features & Advantages
CFD-Optimized Hydraulics
Developed using Computational Fluid Dynamics (CFD), the hydraulic system achieves high efficiency, stable flow characteristics, and proven field performance.
Precision Hydraulic Modeling
The theoretical hydraulic model, supported by laboratory simulation, ensures optimized flow behavior that meets or exceeds customer process expectations.
Clean, Smooth Flow Path
A polished, smooth internal flow surface eliminates dead zones, prevents liquid residue, and allows easy cleaning-critical in polymer slurry handling.
High-Precision Alloy Impeller
The impeller is crafted from low-density forged alloy, machined on advanced multi-spindle machining centers for superior strength and dimensional accuracy.
Advanced Triple Mechanical Seal System
A unique triple mechanical seal structure dramatically improves shaft sealing reliability.
A built-in cooling system for internal bearings ensures steady operation under changing loads and temperatures.
Designed for Severe Operating Conditions
Suitable for high-flow, high-density, abrasive slurry, and chemical media commonly found in PP/PE/LAO/PAO loop reactor systems.
