Progressive Cavity Pumps for Marine Sewage & Blackwater
Controlled positive-displacement transfer for shipboard sewage, blackwater and solids-bearing wastewater streams.
Positive displacement for variable wastewater streams
Marine sewage and blackwater can contain suspended solids and exhibit changing consistency as vessel operating conditions vary. Progressive cavity pumps can provide steady transfer for selected collection, holding-tank and treatment-system duties when the inlet arrangement and pump speed are matched to the actual fluid.
Solids, suction and vessel layout matter
Selection should include minimum and maximum flow, pressure, solids characteristics, viscosity, suction lift and piping losses. Vessel installations may impose compact layouts and intermittent duty, so access, maintenance and pump protection should be considered with the hydraulic requirements.
