Sludge Pumps
OW-HD pumps handle muddy water and suspended solids with cast-iron hydraulic parts, high-chrome alloy wear parts and free passage up to 19.5 mm.
Slurry Pumps
OW-SDA agitator slurry pumps move sand, sediment and abrasive slurry with high-chrome impeller, agitator and inlet-plate construction.
Applications
ONE WHALE focuses on industries where uptime, wear resistance and application-based pump selection matter most.
MiningReliable dewatering and abrasive slurry handling for mine sites and process areas.
TunnelingContinuous drainage and muddy-water transfer for underground excavation and temporary pumping systems.
Construction DewateringPit, foundation, basement and bypass dewatering for civil engineering and building projects.
Quarry & AggregateSand, grit and solids-laden water pumping in quarry operations and aggregate processing sites.
WastewaterSludge movement, sump drainage and solids-laden liquid transfer in wastewater environments.
Industrial DrainageGeneral industrial drainage, process water control and site water management.
Product construction
Key construction details from the supplied product materials, focused on wear life, motor protection and serviceability.
01
Motor protection system
Protection features for dependable operation under continuous-duty and variable site conditions.
02
Mechanical seal system
Mechanical seal and oil chamber arrangement designed to help protect the motor side during submersible duty.
03
