Progressive Cavity Pumps for Marine Bilge, Sludge & Waste Oil
Controlled positive-displacement transfer for variable shipboard mixtures of oil, water, sludge and suspended solids.
Transfer fluids whose composition changes during operation
Bilge, sludge and waste-oil streams can vary from relatively free-flowing oily water to viscous mixtures containing sediment and suspended solids. Progressive cavity pumps can provide steady positive-displacement transfer across a useful range of viscosities when inlet conditions, speed and materials are selected around the complete duty.
Select for the worst credible mixture
Fluid viscosity, solids loading and temperature can change substantially during tank stripping or bilge transfer. The pump should be evaluated for the most difficult expected condition, including suction lift, line losses, particle characteristics and discharge pressure.
