DEMA irrigation products for nurseries and greenhouses

DEMA build proportional injectors — the dosing end of a fertigation system, putting nutrient into the line at a fixed ratio regardless of flow. Straightforward, serviceable equipment for growers who need the mix right rather than the dashboard pretty.

Buying DEMA products from ML Irrigation

We sell DEMA equipment wholesale to production nurseries, greenhouse operations and horticulture education programs, from our warehouse in Fountain Inn, South Carolina, and ship to growers in all 50 states. Will-call pickup is available during business hours.

The DEMA range published by the manufacturer is larger than what any distributor lists online. If the model, size or spacing you need is not on this page, send the part number or describe the job and we'll quote it. For a full system we would rather see your water source, pressure and crop first: tell us those and we'll help you spec it from the pump to the plant.

Need DEMA pricing or a part that is not listed? Send the part number or describe the job and we'll quote it within one business day.
