This pump features a rear-opening design, making it easy to operate and ensuring long-term reliability. It is equipped with a low-noise motor that operates about 10dB quieter than similar products. Before leaving the factory, each unit undergoes a rigorous 2.4MPa pressure test to guarantee safe performance. The open structure allows for simple maintenance without the need to disassemble the pump body or inlet and outlet pipes, offering great versatility in installation. With only four types of shafts, bearings, and coupling covers, spare parts are minimized, simplifying both repair and management. The impeller comes with a seal ring that can be easily overhauled, and the rear cover includes a balance hole to reduce axial wear. A mechanical sealing system ensures no leakage from the bronze impeller even under high water pressure. The stainless steel shaft and imported bearing structure offer options for dry grease lubrication or wet oil lubrication. Advanced design software and hydraulic models are used, along with CNC machining for precision. All impellers pass strict dynamic balance tests. The double scroll design uses high-quality mechanical seals, and various lubrication systems are available for convenience, quick maintenance, and reliable performance. The pump is fitted with a high-quality double-row thrust ball bearing, providing a minimum service life of five years. It is available in cast iron, bronze, and special alloys, suitable for different installation requirements. Its compact size saves floor space and allows flexible installation in any direction. A high-position motor helps prevent flooding. The pump has a vertical structure with equal diameter inlet and outlet ports aligned on the same center line, allowing it to be installed like a valve in pipelines. Its compact and elegant design reduces building costs and is ideal for outdoor use. The impeller is directly mounted on the motor’s extension shaft, resulting in a short axial dimension. Bearings are arranged rationally to effectively balance radial and axial loads, ensuring stable operation and minimal vibration and noise. Installation and repair are quick and straightforward—no need to disassemble the piping. Simply remove the coupling nut to extract all rotor components. The pump supports both series and parallel operation, allowing adjustments in flow rate and head as needed. It can be installed vertically or horizontally depending on pipeline layout. The flow range spans from 1.5 to 1600 m³/h, with a lift capacity between 5 and 125 meters. It is available in basic, split, and cut types to suit various applications.
