Dempster Pumps
The Dempster family of NH3 pumps feature the large capacity B-4, which at .124 gallons per stoke is nearly double the volume of pump currently on the market. This translates to 220 + lb per acre of Nitrogen on the largest of toolbars (47′ and above). This large displacement make possible these maximum rates while lowering pump RPM’s into the 250-350 RPM range, allowing for longer bearing and seal wear. Also, valve “floating” is greatly diminished and “positive” displacement is fully achieved. The versatole B-3 is equal in displacement to current market (.0772 gallons per stroke) and offers a lucrative price in comparison. This time proven pump is a logicak and well matched system fro machines from 22′ to 42′ in width.
