mechanical double diaphragm metering pump with alarm detection

Mechanical double diaphragm metering pump adopts the static seal design of liquid end diaphragm, avoiding the dynamic seal problem of traditional pump type.

Description

mechanical double diaphragm metering pump Technical parameters:

  • Flow rate range: 40 to 240L/H
  • Maximum pressure: 0.8Mpa
  • Diaphragm material: PTFE (overflow end face)
  • Pump head material: PVC, PVDF (PTFE), 304, 316 (optional: duplex steel, Alloy C-276, 904, titanium, zirconium, etc.)
  • Motor: 380V, 3PH, 50HZ (optional: 110-480V, single-phase, 60HZ, inverter/explosion-proof/explosion-proof inverter, etc.)

mechanical double diaphragm metering pump Technical features:

  1. No dynamic seal, no leakage: Static seal design avoids dynamic seal problems, ensuring zero leakage for high-security, leak-free applications.
  2. Suitable for special media: Safely transports dangerous, corrosive, or radioactive liquids—chemicals, acids, alkalis, pesticides, wastewater agents, etc.—preventing environmental and operator risk.
  3. Simple structure & efficient performance: Durable, easy-to-maintain design, more robust than plunger pumps but simpler than hydraulic diaphragm pumps.
  4. Digital control: Can be equipped with a digital controller for local and remote monitoring, making operation intelligent and convenient, even in hazardous environments.
  5. Five-layer composite diaphragm: Enhanced durability and leak prevention—super-tough acid-resistant film, elastic rubber, iron core, reinforced nylon fiber cloth, and wrapped elastic rubber.
  6. Stainless steel reinforced design: Plate behind diaphragm for higher pressure tolerance and longer life, even in frequent operation.
  7. Metering accuracy & flow stability: Flow change controlled within 10% even when pressure changes, suitable for demanding metering applications.
  8. Double diaphragm & diaphragm alarm: Built-in alarm detection system prompts timely inspection and maintenance in case of diaphragm damage or leakage.

Advantages of mechanical double diaphragm metering pump:

  • High corrosion resistance: PTFE overflow end meets high-corrosive liquid transport requirements.
  • Long-lasting durability: Five-layer diaphragm and stainless steel reinforcement extend diaphragm life.
  • Low maintenance costs: Static seal design reduces wear, leakage risk, and seal replacement frequency.
  • High safety: Double diaphragm and alarm detection system protect against leakage and safety hazards.
  • Adaptable: Stable in various media and environments, suitable for chemical, pharmaceutical, environmental protection, and more.

Application fields:

  • Chemical industry: Conveying corrosive/toxic liquids (acids, alkalis, solvents, reagents).
  • Pharmaceutical industry: Precise delivery of agents, high-purity solutions, reagents in drug production.
  • Environmental protection: Sewage and wastewater treatment, pharmaceutical dosing.
  • Petrochemical: Oil and gas industry for chemicals, corrosive liquids, lubricants.
  • Agriculture/horticulture: Precise spraying of pesticides, fertilizers, and other liquids.
  • Food & Beverage: Accurate delivery of additives, spices, flavorings, etc.
  • Water treatment: Precise dosing for drinking/industrial water (pharmaceuticals, disinfectants).
