Dositec EFR® 1250D High Volume Diaphragm Adjustable Chemical Dosing Pump

The Dositec EFR® 1250D is a high volume diaphragm chemical dosing pump designed for reliable and accurate dosing of fertilisers, chemicals and process liquids in demanding agricultural, industrial and water treatment applications. The diaphragm design provides safe, leak-resistant chemical dosing while maintaining excellent performance in continuous-duty environments.

With a maximum flow rate of 1250 L/h and a maximum operating pressure of 5 bar (73 PSI), the EFR® 1250D is well suited to high-capacity dosing systems requiring dependable chemical injection and smooth operation. The pump features a mechanically actuated diaphragm with variable eccentric regulation, allowing the dosing output to be manually adjusted from 0–100% to suit varying process requirements.

Manufactured using durable materials including PP, PVDF and SS316, the EFR® range offers excellent chemical compatibility across a wide range of applications. Powered by a robust 2 HP electric motor, the pump is engineered for long service life, low maintenance and continuous operation in demanding environments.

The Dositec EFR® 1250D is ideal for fertigation, chemical dosing, industrial processing and water treatment systems where reliable, accurate and high-volume diaphragm dosing is required.
