Diaphragm dosing pump

PDM diaphragm metering pump

Based on the principle of reciprocating diaphragm motion, PPM diaphragm metering pumps are ideal for many chemical dosing applications. Their robust design requires minimal maintenance, providing a cost-effective and efficient solution. Here are their features:

  • Accurate dosing of ±1%
  • Made with premium and 100% recyclable materials
  • Flow range on pure water: from 1 to 10,000 L/h
  • Maximum suction height: 6 meters
  • HDPE structure and PVDF liquid head, compatible with many chemicals
  • High-pressure operation and resistance to aggressive products

PPM diaphragm metering pumps are available in several models to suit different flow rates and can be integrated with other 1H2O3 systems to create a customized, turnkey process.

SKU: PDM Category:

Designed for industrial chemical dosing and high-pressure liquid transfer, the 1H2O3 diaphragm metering pumps ensure accurate and reliable dosing. Thanks to their rugged design, they are compatible with a wide range of chemicals, including aggressive fluids.
These models have been developed to dose precise quantities of high-pressure products, with a suction head of up to 6 m, guaranteeing optimal and safe operation.

How PDM works

The operation of diaphragm metering pumps is based on the reciprocating movement of a flexible diaphragm that generates suction and discharge phases. Unlike peristaltic pumps, the fluid is not moved by compression of a tube but by the volume variation of a hermetic chamber.

  • Solenoid activation : A magnetic field attracts the armature, thus displacing the membrane.
  • Suction phase : the diaphragm retracts, creating a vacuum that draws the fluid into the chamber via the suction valve.
  • Discharge phase : When the solenoid is released, a spring returns the diaphragm to its original position, pushing the fluid toward the outlet through the discharge valve.
  • Precise and adjustable dosing : the stroke length and pulse frequency can be adjusted using a potentiometer, allowing optimal flow control.

Advantages of chemical dosing with 1H2O3 diaphragm dosing pumps

  • Accurate and reproducible dosing : Our dosing pumps guarantee dosing accuracy with a reproducibility of ±1% and a measuring capacity of ±5%.
  • High pressure and efficient suction : Designed to operate at high pressure, they can reach a suction height of up to 6 meters.
  • Self-priming and dry running: They can boot automatically and run dry without the risk of damage to internal components.
  • Wide chemical compatibility : Thanks to their PVDF liquid head and PTFE seals, they are resistant to harsh and corrosive chemicals.
  • Easy and low maintenance : Their robust design minimizes wear and tear and requires no special maintenance.
  • Simplified integration : Easily connected to other control systems, they allow for automated and optimized dosing.
  • Reliability and durability : Ceramic ball valves provide excellent wear resistance, extending the life of the equipment.

The 1h2o3 diaphragm metering pump can be used in many areas of application for chemical dosing depending on the type of head, including:

  • Dosage of chemical products : iron chloride, sodium hypochlorite, sulphuric acid, flocculant, hydrochloric acid, etc.
  • Drinking water treatment : disinfectant dosing
  • Cooling circuits : dosing of corrosion inhibitors and biocides
  • Wastewater treatment : dosing of flocculants
  • Paper and plastics industry: additive dosing
  • Chemical dosing for disinfection
  • Public and collective swimming pool water treatment
