At Jiangsu Manqi Machinery Co., Ltd., we specialize in manufacturing high-performance replacement components for pumping systems. The Shanghai Kaiquan Pump WQ2327-672-250 Submersible Pump Impeller is a precisely engineered, wear-resistant part designed to restore and enhance the efficiency of WQ series submersible pumps used in demanding wastewater and drainage applications. Crafted from premium alloy materials, this impeller provides extended service life and dependable operation even in harsh environments containing abrasive solids. Our factory, located in Suzhou, Jiangsu, combines advanced casting techniques with rigorous quality control to deliver components that meet or exceed OEM standards.
Key Features & Technical Specifications
- Premium Wear Resistance – Made from high-chromium alloy iron with optimized carbide structure, achieving surface hardness up to HRC 60. This significantly reduces erosion from sand, debris, and other suspended solids.
- Precision Fit – Manufactured using investment casting and CNC machining to strict tolerances, ensuring perfect balance and smooth operation without vibration or excessive stress on the motor.
- Corrosion Resistance – The alloy composition provides excellent resistance to mildly acidic or alkaline wastewater, further extending the component’s lifespan.
- Heat Treated – A specialized heat treatment process (quenching + tempering) enhances toughness and prevents brittle fracture under high load or cavitation conditions.
- Direct Replacement for Kaiquan WQ2327-672-250 – Designed to match the original impeller dimensions, vane profile, and hub configuration for easy installation without modifications.
- Optional Coating – For extremely abrasive media, we can apply a ceramic-epoxy coating on the wearing surfaces (consult with our sales team for availability).

Frequently Asked Questions
-
Q: Is this impeller a direct replacement for the Kaiquan original part?
A: Yes, it is designed to match the OEM dimensions, vane geometry, and mounting specifications for the WQ2327-672-250 model. However, we recommend comparing with your original part or providing the pump serial number for confirmation before ordering. -
Q: What material is used for this impeller?
A: We use high-chromium wear-resistant cast iron (typically 25-30% Cr), heat-treated to achieve a hardness of HRC 55-60. This material offers excellent abrasion resistance and moderate corrosion resistance for most wastewater environments. -
Q: How long does this impeller typically last in a sewage pump?
A: Service life depends on the concentration of abrasive solids, flow rate, and operating conditions. In typical municipal sewage applications, users report lifespan 2-3 times longer than normal cast iron impellers. In heavy sand-laden water, it can still last 1-2 years under normal maintenance. -
Q: Do you offer any warranty for this component?
A: We provide a standard 12-month warranty against manufacturing defects (material, casting flaws, or dimensional inaccuracy). Wear-related failures due to normal operation are not covered, but we can discuss extended warranty options for long-term contracts. -
Q: Can this impeller be used with other brands of submersible pumps?
A: It is specifically designed for Kaiquan WQ2327-672-250. However, we can supply custom-dimension impellers for other pump brands (e.g., Flygt, Grundfos, Sulzer) upon request. Please provide your pump model and shaft dimensions for a quotation. -
Q: What is the price and shipping time?
A: Price depends on quantity and current material costs. For inquiries, please contact our sales team. Typical production time is 15-25 working days after order confirmation. Stock items can ship within 7-10 days. We ship via sea from Shanghai port or via air if urgent. -
Q: Is custom coating available for extra wear resistance?
A: Yes, we offer an optional ceramic-epoxy coating that can be applied to the impeller vane surfaces and edges. This is recommended for pumps handling extremely abrasive media such as mining slurry or grit-laden water. Contact us for details. -
Q: How should I store or handle the impeller before installation?
A: Keep it in a dry environment, protected from impact. The casting surface is hard but can chip if dropped on concrete. For long-term storage, apply a light anti-rust oil to the machined surfaces (hub bore and keyway).
