Progressive Cavity Pumps for Power Generation
ACCA progressive cavity pumps provide controlled positive-displacement pumping for FGD slurry, power-plant wastewater sludge and treatment-chemical feed.
Controlled flow for demanding power-plant fluids
A helical rotor turning inside an elastomeric stator creates sealed cavities that progress from suction to discharge. This positive-displacement principle produces steady, low-pulsation flow approximately proportional to speed and gives ACCA pumps strong application potential for viscous, abrasive, solids-bearing and metered process streams.
VFD speed control provides useful turndown for chemical feed and variable process demand. In abrasive FGD and sludge duties, pump speed, differential pressure, rotor surface, stator elastomer and solids characteristics are evaluated together to balance required capacity with wear life.
Application engineering around solids and chemistry
Limestone, gypsum, wastewater residuals, polymers and treatment chemicals create very different operating conditions. ACCA evaluates density, viscosity, particle size, solids concentration, pH, temperature, suction conditions and required pressure before selecting displacement, stages, materials, sealing and drive torque.
Power-generation progressive cavity pump applications
FGD Slurry
Abrasive limestone, gypsum and scrubber slurry duties requiring solids and wear evaluation.
Wastewater Sludge
Controlled transfer of solids-bearing power-plant wastewater and treatment sludge.
Data ACCA uses for pump selection
Provide required flow and turndown, suction and discharge pressure, solids concentration and particle size, density, viscosity, temperature, chemical composition, operating hours and available suction conditions. ACCA uses these data to evaluate pump size, speed, staging, rotor/stator materials, elastomer compatibility and drive requirements.
From application to pump and parts support
As ACCA’s new-pump pages are expanded, this hub will connect power-generation duties to appropriate pump families and model-specific engineering data, with direct pathways to rotors, stators, joint components and other replacement parts for long-term service support.
