Product Details
Fully enclosed magnetic seal, zero leakage and no pollutionuses static seals to replace traditional mechanical shaft seals. The flow-passing parts are completely sealed and isolated, completely eliminating leakage and volatilization of media. The delivery of toxic and highly corrosive liquids will not pollute the workshop, creating a leak-free chemical production workshop.
Anti-corrosion engineering plastic one-piece pump bodyThe pump casing, impeller, inner rotor, and isolation sleeve are all made of anti-corrosion resistant nano-plastics and are injection molded in one piece. FRPP is available for general use at room temperature, and PVDF is a high-temperature and strong corrosion material. It is acid and alkali resistant, chromic acid resistant, and organic solvent resistant. It is suitable for most corrosive liquid working conditions.
High temperature resistant permanent magnet, long-term stable and non-fading magnethas a built-in ferrite permanent magnet component, which is magnetically stable under high-temperature conditions and will not cause excitation loss or torque attenuation. It can operate continuously for 24 hours for a long time. The applicable medium temperature range is - 30℃~60℃.
Wear-resistant self-lubricating sliding bearing systemThe moving ring, bushing, and sliding bearing are made of acid and alkali-resistant graphite and PTFE materials. They have their own medium lubrication grooves. They rely on the delivery of chemical liquid for self-lubrication, without the need for external independent cooling water, simplifying the supporting pipelines and reducing energy consumption.
External mixed gas-liquid separation self-priming structureThe pump body integrates a liquid suction chamber, a liquid storage chamber, and a gas-liquid separation chamber. When it is turned on, it automatically stirs the air and water to mix to complete air separation. It can automatically re-establish the vacuum after the pipeline is emptied. The maximum self-priming height is 3 meters. There is no need for a bottom valve or manual pump filling.
Back-pull disassembly structure, convenient maintenanceDirect-coupled back-pull design. When inspecting and replacing impellers, bearings, and seals, there is no need to disassemble the inlet and outlet pipelines. Maintenance can be completed by directly pulling out the internal components backwards, greatly shortening downtime and maintenance time.
Horizontal compact body, small footprint and smooth operationThe horizontal base integrated layout makes the whole machine compact in size and takes up less equipment space; the coaxial direct-coupled transmission has low vibration amplitude and low operating noise. It is suitable for small integrated filters, waste gas towers, and compact automated production lines.
The external magnetic steel is directly connected to the motor, and the transmission is efficient and low-noise.The external magnetic component is directly connected to the motor output shaft, and the torque is transmitted through contactless magnetic coupling. The power loss is low, the transmission efficiency is high, and the operating vibration and noise are much lower than traditional mechanical pumps.
Explosion-proof motor is optional, suitable for flammable and explosive working conditionsAll series of models can be equipped with explosion-proof three-phase motors. When transporting alcohol, ketones, and various volatile organic solvents, it eliminates the risk of static electricity fire and meets chemical explosion-proof safety production standards.

The standard design pressure of the whole machine is 0.6MPa, the applicable temperature range of the medium is - 30℃ to 60℃; the standard self-priming height is 3 meters; if the specific gravity of the conveyed medium is greater than 1.3g/cm³, you must inform it in advance when ordering, and customize the increased torque magnetic steel components; the whole series can be equipped with three types of supporting monitoring devices: anti-idling protection, liquid leakage monitoring, and medium temperature measurement.
is used for the external circulation of nickel, copper, zinc, chromium, and chemical plating solution tanks, and is used in conjunction with HL and HCL vertical filter units; the FRPP/PVDF anti-corrosion pump body is resistant to acid, alkali, and chromic anhydride corrosion in the plating solution. The 3-meter self-priming height can directly extract the solution from the underground storage tank without being immersed in the tank for installation.
transports acidic etching liquids, alkaline etching liquids, micro-etching liquids, and developing neutralizing liquids. The PVDF material model is suitable for strong oxidation and high-corrosion etching liquids; the magnetic leakage-free structure prevents liquid leakage from contaminating the board surface, and reduces pinholes and poor oxidation defects.
Acid and alkali waste gas neutralization and spray water are cyclically transported. The horizontal compact body can be installed in a small space at the bottom of the tower. The self-priming structure does not require a bottom valve. It can automatically rebuild vacuum suction after shutdown. It is suitable for unattended environmental protection equipment.
Various types of weak acid, weak alkali, and organic solvent raw materials are transported in a closed cycle. The optional explosion-proof motor model is suitable for alcohol and ester volatile media; all plastic flow parts have no metal precipitation, ensuring the purity of chemical raw materials.
Electroplating comprehensive acid-base wastewater and cleaning wastewater are lifted and transported. The low-power model is adapted to the integrated small wastewater station. It can extract waste liquid from underground wastewater pools from a long distance, simplifying the pipeline layout and saving equipment space.
Small proofing plating tank, chemical dispensing circulation, HCQF-100 minimum flow model has a small body and is suitable for the narrow space of the operating table. The corrosion-resistant material is suitable for various experimental corrosion chemicals.
Medium specific gravity specification: The standard factory model is only suitable for liquids with a specific gravity ≤1.3g/cm³. If the specific gravity of the liquid exceeds this value, it must be informed at the ordering stage and high-torque reinforced magnets can be customized to prevent the magnets from decoupling and idling to burn the motor.
Media particle restrictions: This machine is strictly prohibited from transporting media containing hard particles and large amounts of crystallized precipitates. The solid particles will quickly wear the graphite/PTFE sliding bearings, causing sealing failure and liquid leakage.
Idling operation is prohibited: Before starting the pump, it must be ensured that the inside of the pump chamber is completely filled with liquid, and dry running without medium is absolutely prohibited; in the idling state, the bearings are not lubricated by medium, and the isolation sleeve will be worn in a short period of time, causing corrosive medium leakage accidents.
Material temperature distinction: FRPP pump body is suitable for weak acid and weak alkali liquids at room temperature of ≤60℃; PVDF fully anti-corrosion pump body must be used to transport high-temperature chromic acid and strong oxidizing liquids. High temperature will accelerate the aging and cracking of FRPP material.
Explosion-proof working conditions requirements: When transporting flammable and explosive organic solvents such as acetone, alcohol, and xylene, the entire machine must be equipped with an explosion-proof three-phase motor; ordinary motor wiring and heat dissipation do not have explosion-proof protection structures, which poses major safety risks of fire and explosion.
