Jiangsu Manqi Machinery Co., Ltd., established in 2017 and located in Suzhou, Jiangsu, China, is a professional manufacturer specializing in high-quality pump components and industrial machinery parts. With a factory area spanning 10,000–30,000 square meters and a dedicated team of 11–50 experienced employees, we are committed to delivering durable and precision-engineered products for global clients. Our annual export value exceeds US$1 million, serving markets across Eastern Europe, Southeast Asia, Africa, and South Asia. We are proud to present the Shanghai Kaiquan KQSN250-M9/327 Pump Wear Ring, a critical replacement part designed specifically for split case pumps. This wear ring is manufactured to meet the original equipment manufacturer (OEM) specifications, ensuring seamless fit, reliable performance, and extended service life for your pumping system.
The wear ring is a vital component in split case pumps, reducing leakage between the impeller and casing, thereby maintaining pump efficiency and preventing premature wear. Our KQSN250-M9/327 wear ring is crafted from high-quality materials, rigorously tested, and available in customizable options to suit diverse operating conditions. Whether for water supply systems, irrigation projects, HVAC installations, or industrial fluid handling, this wear ring delivers consistent performance and reduces downtime.
Key Features & Technical Advantages
Precision Engineering: Manufactured using advanced CNC machining and strict quality control processes to ensure dimensions match the original Kaiquan KQSN250-M9/327 specifications. Tolerances are maintained within ±0.05mm for a perfect fit.
Material Options: Available in stainless steel (304, 316) or high-grade cast iron, with optional surface hardening treatments to resist abrasion and corrosion. Materials are selected based on the application environment — ask our team for recommendations.
Enhanced Efficiency: By minimizing internal leakage, the wear ring helps maintain the pump's hydraulic efficiency at optimal levels (up to 85% efficiency retention under normal conditions). This directly reduces energy consumption and operating costs.
Extended Pump Life: Protects the more expensive impeller and casing from wear, postponing major overhauls. Typical service life of our wear ring is 2–3 years under standard water treatment conditions, depending on the fluid properties.
Easy Installation: Designed as a direct replacement part, no modifications required. Each ring comes with clear installation instructions and can be fitted by a qualified technician within 1–2 hours.
Customizable: If your pump has slightly different dimensions or you require a specific material or hardness, we offer customization services. Minimum order quantity (MOQ) and lead time are available upon request.
Comprehensive Quality Testing: Each batch undergoes dimensional inspection, material composition analysis, and hardness testing. A test report can be provided with each shipment.
