Product Details
IE5 ultra-efficient energy-saving motorThe motor energy efficiency grade exceeds IE5, and the overall efficiency of the whole machine is 65%; the low-frequency 30Hz operating efficiency is still greater than 52%; the pump body adopts a volute-type overflow structure, with low fluid inlet and outlet resistance, and full frequency conversion speed regulation to maintain high energy-efficiency operation, significantly reducing the long-term electricity cost of the production line.
AC and DC dual power supply universal interfaceThe innovative integrated power module can be directly connected to AC380V industrial alternating current or DC550V direct current power supply without the need for additional power conversion equipment. It is suitable for diversified power supply solutions for new energy equipment and automated integrated production lines.
Compact modular structureHorizontal integrated modular design, the volume of the whole machine is 50% smaller than that of ordinary magnetic pumps with the same parameters. It can be installed on equipment racks, small integrated filtration units, and small lab consoles, and has strong space adaptability.
High viscosity/large specific gravity media adaptationThe high-torque permanent magnet drive structure can transport high-viscosity, high-specific-gravity corrosive liquids; the medium is allowed to have a higher specific gravity under low-speed frequency conversion conditions. The pump body and impeller have strong load-resistance capabilities and have a longer service life in 24-hour long-term continuous operation.
4~20mA standard flow controlIndustrial general-purpose 4~20mA analog signal stepless speed regulation, no need for complex programming and debugging; multiple types of industrial communication interfaces are reserved, which can be directly connected to PLC, touch screen, and automated central control system, and the circulation flow is accurately controllable.
Ultra-high insulation safety protectionThe insulation standard of the whole machine is 1kV, the insulation resistance is greater than 1MΩ, and it is not prone to leakage in high-humidity and corrosive workshops. It is suitable for high-humidity corrosive production environments such as electroplating and etching, and the operation is stable and safe.

When operating at maximum flow rate and rated maximum lift at full load, the specific gravity of the transported liquid must not exceed the limit value marked on the corresponding model; under low speed and frequency conversion conditions, the equipment can be adapted to media with higher specific gravity. For special high specific gravity conditions, technical personnel can be consulted to customize an exclusive solution.

Media specific gravity distinction: the conventional HTM standard model without D suffix is suitable for liquids with a specific gravity within 1.2; the enhanced torque model with D suffix is suitable for liquids with a specific gravity of up to 1.5. High specific gravity media such as chromic acid and chemical plating are preferred for D series models.
Power supply scheme classification: The factory 380V AC automated production line uses the standard HTM model; new energy lithium battery equipment and DC power supply integrated equipment use the D suffix AC and DC universal model.
Flow lift selection: If the vertical height of the pipeline is high and multi-layer filtration units are connected in series, the 32m/34m high lift and high-power model is preferred; for short-distance small tank circulation, the DN40 small-diameter low-power model can be selected.
Frequency conversion control description: The whole series comes standard with 4~20mA standard industrial speed regulation signal, which can be directly connected to PLC and touch screen without the need for additional driver modules, and supports multi-protocol communication expansion.
Space adaptation tip: The volume of the whole machine is only 50% of that of a traditional magnetic pump. It can be installed on built-in racks, integrated filter units, and small laboratory consoles. Before purchasing, confirm that the DN diameter of the on-site flange pipeline matches.
