Jiangsu Manqi Machinery Co., Ltd., a professional manufacturer established in 2017 with a factory spanning 10,000-30,000 square meters in Suzhou, Jiangsu, proudly presents the DFSS600-24/6/220 Rotor Assembly – a high-capacity rotor specifically designed for Shanghai East centrifugal pumps. This rotor assembly is engineered to deliver exceptional flow rates and reliable performance in demanding industrial applications. With our dedicated team of 11-50 skilled workers and a growing export network across Eastern Europe, Southeast Asia, Africa, and South Asia, we ensure that every component meets rigorous quality standards. Whether you are replacing a worn-out rotor or upgrading your pumping system, our DFSS600 rotor assembly offers a perfect balance of durability, precision, and cost-effectiveness.
The DFSS600-24/6/220 rotor assembly is a critical component of the Shanghai East DFSS series double-suction centrifugal pumps, widely used in water supply, drainage, HVAC, and industrial circulation systems. Its big capacity design allows for efficient handling of large volumes of water or other fluids, making it ideal for municipal water plants, power stations, and irrigation projects. Each rotor is precision-machined using high-grade materials to ensure long service life, low vibration, and minimal maintenance. Below we detail the key features and technical specifications.
Key Features & Benefits
- High Capacity Performance: Specifically designed for the DFSS600 pump, this rotor assembly delivers a large flow capacity (up to 1,200 m³/h depending on system conditions), ensuring efficient fluid transfer even in demanding applications.
- Precision Engineering: Manufactured with strict tolerance control – the impeller is dynamically balanced to ISO 1940 G6.3 grade or better, reducing vibration and extending bearing life.
- Durable Material Options: Available in stainless steel (SS304, SS316) or ductile cast iron (QT450-10) to suit different fluid types, including clean water, seawater, and mildly corrosive liquids.
- Direct Replacement: Designed as a direct fit for Shanghai East DFSS600 series pumps – no modifications required. The shaft diameter, keyway, and bolt pattern are identical to the original OEM specifications.
- Enhanced Reliability: Each rotor assembly undergoes 100% inspection including dimensional checks, hardness testing, and run-out verification. This ensures consistent performance and reduces unplanned downtime.
- Customizable Options: We offer optional coatings (e.g., epoxy, rubber lining) for abrasive or corrosive fluids, as well as alternative shaft materials (2Cr13, 3Cr13) upon request.

Frequently Asked Questions
-
Q: Is this rotor assembly compatible with all Shanghai East DFSS600 pumps?
A: Yes, it is designed as a direct replacement for the original DFSS600-24/6/220 rotor. The shaft dimensions, impeller diameter, and bolt pattern match the OEM specifications. However, we recommend verifying the exact pump model and serial number to ensure perfect fit. -
Q: What material is the rotor made of?
A: Standard options are cast iron (QT450) and stainless steel (SS304 or SS316). For special fluids, we can supply rotors with duplex stainless steel or rubber lining – please inquire for custom requirements. -
Q: How long does the rotor typically last?
A: Service life depends on operating conditions (fluid type, temperature, contamination, duty cycle). Under normal clean water conditions, the rotor can last 5-8 years. Regular inspection and maintenance will extend its life. -
Q: Do you offer a warranty?
A: Yes, we provide a 12-month warranty from the date of shipment covering manufacturing defects. Damage caused by improper installation, wear, or misuse is not covered. -
Q: Is the rotor balanced before shipping?
A: Absolutely. Each rotor assembly is dynamically balanced to G6.3 grade or better. We provide a balancing report upon request. -
Q: What is the packaging like for export?
A: The rotor is securely packed in a wooden crate or plywood box, with foam padding to prevent movement. The package is suitable for sea freight and complies with international shipping standards. -
Q: Can I install this rotor myself?
A: We recommend installation by a qualified technician familiar with centrifugal pumps. A detailed installation manual is included with the product. For complex setups, we can arrange remote guidance. -
Q: What is the lead time for this rotor?
A: For standard rotors, lead time is 15-20 working days after order confirmation. Customized orders may take 25-30 working days. We can expedite urgent orders based on stock availability.
