mechanical diaphragm metering pump with static seal

mechanical diaphragm metering pump Technical parameters:

• Flow rate range: 10 to 500L/H, adapts to various liquid transport scales.
• Maximum pressure: 1.2Mpa, suitable for higher pressure environments.
• Diaphragm material: PTFE (polytetrafluoroethylene), strong corrosion and temperature resistance.
• Pump head material: PVC, PVDF (PTFE), 304/316 stainless steel for chemical media; optional duplex steel, Alloy C-276, 904 stainless steel, titanium, zirconium, etc. for demanding conditions.
• Motor: 380V, 3-phase, 50HZ (standard); optional 110-480V single-phase 60HZ, frequency conversion, explosion-proof, inverter explosion-proof, etc.

mechanical diaphragm metering pump Technical features:

1. No dynamic seal, no leakage: Static diaphragm seal replaces piston dynamic seal, ensures leak-free operation, ideal for hazardous media and environments requiring zero leakage.
2. Adaptable to various media: Suitable for water, flammable/explosive, toxic, malodorous, radioactive, and other special liquids; widely used in chemical, environmental, pharmaceutical industries.
3. Structural optimization: Simpler than hydraulic diaphragm pumps, but more complex than piston pumps; higher reliability and adaptability, efficient and stable performance.
4. Digital control: Supports digital controller for precise flow regulation, local/remote monitoring for automation and smart production.
5. Five-layer composite diaphragm: Super toughness acid-resistant film, elastic rubber, iron core, reinforced nylon fiber cloth, and wrapping layer for durability and long service life.
6. Efficient operation: Maintains high efficiency even in harsh environments.
7. Stainless steel enhancement: Diaphragm backed with stainless steel plate for increased pressure resistance and overall pump lifespan.
8. Flow accuracy: Lower metering accuracy than piston/hydraulic diaphragm pumps, but flow rate fluctuation kept within 10% across pressure changes, suitable for most industrial flow control needs.
9. Double diaphragm option: Optional double diaphragm with alarm detection for timely feedback, enhanced safety, and stability.

Mechanical diaphragm metering pump advantages:

• Corrosion resistance: PTFE overflow end withstands strong acids, alkalis, corrosive media; ideal for chemical, pharmaceutical industries.
• Long life design: Five-layer composite diaphragm and stainless steel enhancement increase durability and reduce maintenance frequency.
• High abrasion resistance: Alloy copper turbine (4.5x ordinary copper abrasion resistance), heat-treated alloy steel worm for long-term stable performance.

Transmission parts:

• Turbine: Alloy copper, 4.5x wear resistance of ordinary copper, ensures stable and efficient pump operation.
• Worm: Heat-treated alloy steel, high hardness and wear resistance, extends pump service life.
• Manufacturing process: Precision hobbing machine and worm gear grinding; key parts inspected by CNC gear testing center for high efficiency, low noise, and precision.

Application areas:

• Chemical industry: Conveying corrosive, flammable/explosive liquids (acids, alkalis, solvents, catalysts).
• Environmental protection: Wastewater/sewage treatment, chemical dosing (disinfectant, flocculant, etc.).
• Pharmaceutical industry: Accurate conveyance of drug raw materials and solvents.
• Food & beverage: Accurate delivery of additives, flavorings, syrups, juices, etc.
• Agriculture: Pesticide/fertilizer delivery, precise spraying for large-scale irrigation/fertilization.
• Oil & gas industry: Petrochemical and additive delivery, ensuring safe liquid transport.
• Water treatment: Accurate dosing of disinfectants, coagulant aids, etc.
