Rating for My Application 4 Innovative 5

Re: Dairy Farm Pumps

Bell Brands

Columbus, OH
Manure slurry
Average GPM:

We’ve never seen a pump like it. They pump out manure pits and send it to other transfer equipment . Pumping 5-15% solids .


Pump Sourcing Distributor


Columbia, SC
Average GPM:

We recommend the B-DD Series to our customer base because of the low maintenance and down time. Our client base ranges from poultry farm process applications, to pulp and paper and general wastewater transfer. We use three of these units for our pump rental fleet. These cost 30-40% less than renting a dri-prime pump which customers appreciate and have used more often.


Bauxite-Alumina Pump


Baker County, OR
Average GPM:

Bauxite slurry application. Using a fleet of six units at various sites. Work great.
