Dosing pumps and agitators

Electromagnetic, motor-driven and peristaltic dosing pumps for precise chemical dosing. Agitators, measuring instruments and control panels from Etatron DS.

Precise and reliable chemical dosing

Dosing pumps are essential in water treatment plants, chemical-pharmaceutical processes and any application requiring controlled addition of chemicals. Roffia srl distributes the complete Etatron DS range.

Product types

Electromagnetic dosing pumps

Solenoid-driven diaphragm pumps for precise low to medium flow dosing. Ideal for chlorination, pH correction, biocide and flocculant dosing.

Available series

  • eOne: intelligent pump with power control
  • PKX: versatile for standard applications
  • AUREX: reference range
  • DLX/DLXB: high reliability, competitive price
  • TwinPool: dual dosing for swimming pools

Motor-driven dosing pumps

Mechanical diaphragm and piston pumps for higher flow rates and pressures. Heavy-duty construction for continuous industrial processes.

Types

  • Diaphragm: medium flow, aggressive fluids
  • Piston: high pressure, industrial precision dosing

Peristaltic pumps

No fluid contact with mechanical parts — ideal for viscous, abrasive or contamination-sensitive fluids. OEM, CASSA and POOL series.

Agitators and instruments

Chemical tank agitators, pH/Redox/chlorine measuring instruments (eControl, Eligere, Minimus), control panels, probes, electrodes and dosing system accessories.

Domande frequenti

When is a dosing pump needed?
A dosing pump is needed whenever a chemical additive must be injected precisely and continuously: water chlorination, pH correction with acids or bases, flocculant dosing in water treatment, nutrient addition in biogas digesters, antifoam and dye dosing in industrial processes. Flow rates range from a few ml/h to over 100 l/h.
What is the difference between electromagnetic and motor-driven dosing pumps?
An electromagnetic dosing pump uses a solenoid to drive the diaphragm: compact, economical and ideal for low to medium flow rates (up to 20 l/h). A motor-driven pump (mechanical diaphragm or piston) is more robust and suited for higher flow rates and pressures, continuous industrial processes and more viscous fluids.
Does Roffia supply chemical tank agitators?
Yes. We supply Etatron DS agitators for chemical storage tanks. They keep the solution homogeneous before dosing, preventing sedimentation and concentration variations. Available in various power ratings and corrosion-resistant materials.
Which dosing pump brands does Roffia distribute?
Roffia srl distributes dosing pumps, agitators and instrumentation from Etatron DS: electromagnetic pumps (eOne, PKX, AUREX, DLX), motor-driven pumps (diaphragm, piston), peristaltic pumps, pH/Redox/chlorine instruments and control panels. Stock available in Cremona, on order if not in stock.
