The HennviHBY electric diaphragm pump is designed according to the American ABEL pump standards, specifically for low-pressure conditions, with an outlet pressure ≤ 3kg/cm²; Relying on a diaphragm to isolate the medium and transmission structure, it is leak-free throughout, with a self-priming capacity of over 5 meters. It can transport particles within 10mm diameter, high-viscosity slurry, and highly corrosive hazardous chemical media. Flow rate is 0.5~20m³/h, head is 30m, power is 0.75~4kW, and the medium is suitable for temperatures of -20~150°C. Five types of percurrent materials are available: cast iron, aluminum alloy, stainless steel, plastic, and fluorine-lined permeation materials. There are standard and BT4 explosion-proof motor models, widely used in chemical, ceramic, coating, food, and mining wastewater treatment.
Product Details
No need for direct irrigation, with outstanding self-priming performanceUnique diaphragm cavity return structure, self-priming height can reach over 5 meters. No manual filling of medium is needed before starting, and after air suction, suction can be quickly resumed, eliminating the need for foot valves and pre-filling pump steps. Stable conveying can be achieved by direct installation of the low-level material pit on the ground.
Large channels with high permeability, resistant to granular slurryThe internal flow channel is wide and smooth, allowing solid particles within 10mm in diameter, high-viscosity slurry, and fiber slurry to pass smoothly. It is less likely to block or jam the pump, replacing traditional centrifugal pumps and screw pumps for transporting sludge, coatings, and glaze slurry, greatly reducing cleaning frequency.
The diaphragm completely isolates the medium, ensuring zero leakage and no contamination of the workshopThe diaphragm completely separates the conveyed material from the internal transmission assembly, preventing the medium from leaking outward; The pump does not allow oil to seep into the material itself, protecting the drive bearings and reducer while preventing contamination by hazardous chemicals and colored slurries, greatly extending the machine's service life.
Multi-material diaphragms / custom pump bodies, compatible with various corrosive mediaThe separator can be made of neoprene, nitrile rubber, F4, PFA, and various materials; The pump body is made of cast iron, aluminum alloy, stainless steel, engineering plastics, and fluorine-lined linings, suitable for weak acids, strong alkalis, organic solvents, and highly corrosive hazardous chemicals; The motors come in standard and BT4 explosion-proof types, safe for flammable and explosive conditions.

The standard design pressure for the entire machine is 3kg/cm², with suitable media temperature range of -20~90°C, and the custom high-temperature diaphragm model has a maximum temperature resistance of 150°C; If the specific gravity of the conveyed medium exceeds 1.3g/cm³, advance notification of the motor power upgrade must be provided when ordering; The entire series can be optionally equipped with BT4 explosion-proof motors, diaphragms of different materials, and fluorine-lined pump bodies as needed; The diameter of medium particles must not exceed 10mm, and the transport of large hard solids is prohibited.
For transporting various highly toxic, flammable, and volatile hazardous liquids, strong acids, alkalis, and salt-based corrosive agents, priority is given to fluorine-lined pump bodies + PFA diaphragms + BT4 explosion-proof motors; The separator has zero leakage to prevent toxic chemical leakage, and the explosion-proof structure prevents solvent fire and explosion, adapting to reactor circulation and hazardous material transfer.
Transporting paint, resin pigments, and adhesives, using stainless steel/aluminum alloy pump bodies paired with nitrile rubber diaphragms; The main channel does not block material, with no metal impurities precipitating, ensuring uniform coating coloration and is compatible with the coating filter press feeding.
For conveying ceramic glaze slurry, slurry, and ore slurry, the cast iron wide-channel model is suitable for high-solidity slurry, which can replace centrifugal pumps with fine ore particles, preventing glaze slurry sedimentation and pump blockage, and stabilizing the glaze feeding production line.
Conveying jam, mashed potatoes, chocolate syrup, and beer fermentation mash; food-grade rubber diaphragms and stainless steel pump bodies produce no impurities or precipitate, meeting food hygiene standards. They can be used for fermentation tank circulation and filling feeding.
Mine tunnel sewage, plant sedimentation sludge, and chemical waste sludge lifting and conveying; cast iron large-diameter model, resistant to sediment particles, self-priming height suitable for underground sewage tank extraction, compatible with fully automatic sludge filter presses.
Transporting and unloading diesel, engine oil, and various light oils. The explosion-proof entire machine is equipped with an oil-resistant nitrile membrane, sealed with no leakage, eliminating oil waste and fire hazards.
Specific gravity specification for medium: Standard motors should be adapted to a specific gravity ≤ 1.3g/cm³ medium; high-density slurry and heavy metal liquids require increased motor power to prevent overload and motor burnout.
Restrictions on medium particles: The diameter of solid particles in the medium must not exceed 10mm. Oversized hard blocks can pierce the diaphragm, causing large-area leakage. It is recommended to install a simple filtration device at the front end of the feed.
No running idle: The pump chamber must contain medium, and prolonged dry grinding will quickly damage the diaphragm; Intermittent use must ensure that the liquid level in the feed pool is not lower than the suction port.
Medium temperature classification: Suitable for conventional rubber separators - 20~90°C; High-temperature slurry at 90~150°C needs to be replaced with F4/PFA high-temperature resistant separator; ordinary rubber tends to age and crack at high temperatures.
Explosion-proof requirements: When conveying flammable and explosive media such as alcohol, acetone, and paint solvents, the entire machine must be equipped with a BT4 explosion-proof motor. Ordinary motors without explosion-proof protection pose a risk of fire and explosion.
Classification of corrosive media: For strongly corrosive media such as hydrofluoric acid and high-concentration chromic acid, fluorine-lined pump bodies must be paired with PFA diaphragms; Cast iron and ordinary stainless steel can corrode and perforate in the short term.
