Progressive Cavity Pumps for Black Liquor & Process Liquors
Positive-displacement transfer for viscous pulp-and-paper process liquors where concentration, temperature and materials compatibility are critical.
Controlled transfer across changing concentration and viscosity
Black liquor and other mill process liquors can change substantially in viscosity as solids concentration and temperature vary. Progressive cavity pumps can provide controlled positive-displacement flow for selected transfer and process duties when the pump is sized around the full operating envelope.
Chemistry and temperature govern materials selection
Rotor metallurgy, stator elastomer, seals and other wetted components should be reviewed against actual liquor chemistry, concentration and temperature. High viscosity can also increase inlet losses, making suction-line design and pump speed important.
