Capable of transferring liquids with very high apparent viscosity (up to 50,000 cps at 20[degrees]C), even if containing suspended solids, these pumps feature self-priming dry capacity, fine tuning of speed without pressure loss, and the possibility of dry operation without suffering damage.

The [kappa]-carrageenan has the highest index of consistency and apparent viscosity due to their capacity to associate with milk products and proteins (Perez-Mateos, 2001), and their high-water binding capacity, this is likely because of the hydrophilic sugar structure as well as the amorphous molecular arrangement of the polysaccharide chains (Suzuki & Nakagami, 1999).
