mechanical diaphragm metering pump with PTFE overflow ends

Mechanical diaphragm metering pump is a widely used equipment for precision metering and conveying all kinds of liquids, suitable for conveying chemically corrosive, highly toxic or dangerous media.

Description

The mechanical diaphragm metering pump features mechanical diaphragm technology and a no dynamic seal design, effectively avoiding media leakage and ensuring safety and environmental protection.

mechanical diaphragm metering pump Technical Parameters:

  • Flow range: 15 to 130L/H
  • Maximum pressure: 1.0Mpa
  • Diaphragm material: PTFE (overflow end face)
  • Pump head material: PVC, PVDF (PTFE), 304, 316 (options: duplex steel, Alloy C-276, 904, titanium, zirconium, etc.)
  • Motor: 380V, 3PH, 50HZ (Options: 110-480V, single-phase, 60HZ, inverter, explosion-proof, explosion-proof inverter, etc.)

mechanical diaphragm metering pump Technical features:

  1. No dynamic seal, no leakage design: Static sealing design with diaphragm replacing the dynamic piston seal, avoiding leakage and suitable for hazardous media.
  2. Applicable media: Suitable for flammable, explosive, toxic, malodorous, radioactive liquids, as well as water, with guaranteed safety in conveyance.
  3. Structural design: Simpler than hydraulic diaphragm pumps, but more complex than piston pumps; can accurately adjust flow over a wide range of flow and pressure.
  4. Digital control function: Supports digital controller for local operation or remote monitoring; ideal for automated production lines requiring precise flow control.
  5. Durable diaphragm design: Five-layer composite diaphragm (acid-resistant film, elastic rubber, supporting iron core, reinforced nylon fiber cloth, wrapped elastic rubber) for enhanced strength and extended service life.
  6. Stainless steel reinforced design: Stainless steel plate on diaphragm back for extra durability and longer working life.
  7. Flow accuracy: Metering accuracy lower than piston/hydraulic diaphragm pumps. Flow rate fluctuation up to 10% with pressure change, but maintains stability in large flow applications.
  8. Double diaphragm design (optional): Optional double diaphragm with alarm detection for enhanced safety and stability.

Advantages of mechanical diaphragm metering pump:

  • Strong corrosion resistance: PTFE overflow end resists various chemicals, suitable for strong acids/alkalis.
  • High abrasion resistance and long life: Alloy copper turbine (4.5x abrasion resistance of ordinary copper), heat-treated alloy steel worm for greater hardness and durability.
  • High efficiency and low noise: Precision hobbing and worm gear grinding of main transmission parts provide high transmission efficiency and smooth, quiet operation.

Transmission components:

  • Turbine: Alloy copper, higher cost, 4.5x wear resistance of ordinary copper, extends service life.
  • Worm: Alloy steel, heat treated, high hardness and wear resistance for stable long-term operation.
  • Manufacturing precision: Main transmission parts processed by precision hobbing and CNC gear inspection for high efficiency and low noise.

Mechanical diaphragm metering pump application fields:

  • Chemical industry: Conveying chemicals, solvents, corrosive liquids, catalysts, etc.
  • Environmental protection: Wastewater/sewage treatment, acid/alkali liquid transportation.
  • Pharmaceutical: Precise measurement and transport in drug production.
  • Food and beverage: Accurate measurement of additives, flavorings, beverages.
  • Agriculture: Conveying pesticides, fertilizers, and other liquids.
  • Oil and gas: Chemicals and additives, especially in explosion-proof or anti-corrosion environments.
  • Water treatment: Water quality adjustment and agent addition (disinfectants, flocculants).
