1PC 3.5m Ceramic Shaft Water Pump Impeller Rotor, Engraving Machine Cooling Submersible Pump Replacement Rotor Accessories | Engraving Machine Use, Submersible Pump Part, Cooling System, 1 Piece

This model is a replacement rotor for a water pump with a lift of 3.5 meters. It is a ceramic shaft version with an overall length of 90mm (including black rubber ends at both ends); the main body diameter of the magnetic core is 19mm, the length is 41.5mm, and the outer diameter of the six-blade plastic impeller is 45mm. It is composed of four parts: rubber ends, permanent magnet rotor, plastic impeller, and ceramic shaft core. It is suitable for engraving machine spindle cooling submersible pumps. It is also compatible with fish tanks and small waterscape submersible pumps. It is a replacement accessory for the core loss of the water pump. A sealing kit is included with the product, which can directly replace the old rotor to complete water pump repairs. It can be used for both industrial equipment water cooling and household small water circulation equipment.

• Special size adaptation: strictly matches the specifications of the 3.5m head water pump, with a total length of 90mm, a magnetic core of 19×41.5mm, and an impeller of 45mm. There is no gap in assembly, and there will be no jamming, water leakage, or insufficient flow problems after replacement.
• The ceramic shaft is wear-resistant and durable: the built-in ceramic shaft core is more resistant to wear and scale corrosion than ordinary steel shafts. It is less likely to rust and deform after long-term water circulation, which greatly extends the service life of the rotor.
• Integrated permanent magnet power is stable: the high-density permanent magnet core has long-lasting magnetic force, and there will be no head attenuation during long-term use. The water pump has stable pumping power and stable performance under alternating hot and cold working conditions.
• Comes with a sealing kit: The product comes with free sealing accessories. When replacing the rotor, the waterproof sealing is completed simultaneously to avoid water seepage in the pump body, simplifying maintenance steps and reducing the cost of purchasing additional consumables.
