Dositec EFR® 750+750D Dual Head Diaphragm Adjustable Chemical Dosing Pump

The Dositec EFR® 750+750D Dual Head is a high volume dual-head diaphragm chemical dosing pump engineered for accurate and continuous dosing of fertilisers, chemicals and process liquids in demanding agricultural, industrial and water treatment applications. Its dual-head diaphragm design provides high-capacity chemical injection while delivering leak-resistant performance, exceptional reliability and long service life.

Each diaphragm head delivers up to 750 L/h, providing a combined maximum flow rate of 1500 L/h at operating pressures up to 7 bar (102 PSI). The mechanically actuated diaphragm system, combined with variable eccentric regulation, allows the dosing output to be manually adjusted from 0–100%, ensuring precise chemical dosing across a wide range of applications.

Manufactured using durable PP, PVDF and SS316 material options, the EFR® Dual Head diaphragm range offers excellent chemical compatibility for aggressive process fluids. Powered by a heavy-duty 2 HP electric motor, the pump is designed for continuous-duty operation with minimal maintenance and dependable performance.

The Dositec EFR® 750+750D Dual Head is ideal for large-scale fertigation, agriculture, industrial processing and water treatment systems requiring accurate, high-volume dual-stream diaphragm chemical dosing.
