- Key Products/Technologies
- Magnetic Pumps (DMNP series) feature a completely sealed structure with no liquid leakage, achieved through powerful magnetic coupling. Excellent corrosion resistance is ensured by PVDF and ETFE molding and lining within the metal casing. The use of chemical-resistant, heat-resistant, and high-strength SIC materials for shafts and bushings guarantees a long service life. The Back Pull-Out design facilitates easy maintenance, offering high pump efficiency suitable for high head and large capacity applications. 100% localization of parts ensures quick supply and interchangeability.Magnetic Pumps (DMNP series) feature a completely sealed structure with no liquid leakage, achieved through powerful magnetic coupling.

- F.R.P Non-seal Pumps (DFN series) are designed as Non-Seal, No-Bearing types, effectively eliminating the primary cause of pump failures by removing shaft sealing devices. These pumps exhibit excellent heat and corrosion resistance, operating efficiently from -40°C to 160°C. Assembly and disassembly are simplified due to standardized precision molded parts, making maintenance straightforward. Their lightweight design ensures easy handling and installation. High efficiency, low vibration, low noise, and robust mechanical strength are key characteristics.F.R.P Non-seal Pumps (DFN series) are designed as Non-Seal, No-Bearing types, effectively eliminating the primary cause of pump failures by removing shaft sealing devices.

- Rotary Gear Pumps feature hygienic design with stainless steel (STS316) adhesive parts and fully machined internal and external surfaces. A precise gap between the rotor and casing enables the transfer of fluids ranging from low viscosity (water) to high viscosity (20000cp). Both the rotor and casing are precision-cast. Ease of disassembly, assembly, and cleaning is a significant advantage. Interchangeable 1-LOBE and 3-LOBE rotors allow for solid material transfer and pulsation prevention. Options for automatic control valves and Heating Jacket types are available.Rotary Gear Pumps feature hygienic design with stainless steel (STS316) adhesive parts and fully machined internal and external surfaces.

- Vortex Pumps (DV series) are horizontal single-stage non-clog vortex pumps designed according to ISO-2858 standards. They are specifically engineered for the clog-free transfer of solids, slurry, and wastewater. The casing passage is free of obstructions, and the impeller rotates at a distance from the suction side, transferring liquid through the vortex principle. Back vanes reduce axial thrust and stuffing box pressure, extending the lifespan of seals, packing, sleeves, and bearings. The Back Pull-Out type design minimizes maintenance time.Vortex Pumps (DV series) are horizontal single-stage non-clog vortex pumps designed according to ISO-2858 standards.
