Precision in every flow
OWS designs and builds high-performance centrifugal, submersible and multi-stage pumps for clean water, chemical transfer, wastewater, HVAC and energy systems — verified in our own CFD laboratory for maximum hydraulic efficiency.
Engineered for every hydraulic duty
From clean water transfer to heavy sludge and aggressive chemicals. Modular hydraulics, premium materials and short lead times for OEM projects.
Centrifugal Process Pumps
Heavy-duty end-suction pumps for water supply, cooling circuits, chemical transfer and general industry.
Submersible Drainage Pumps
Vortex impellers for sewage, construction dewatering, sump and flooded applications. Sand-resistant.
Multi-stage Booster Pumps
Compact high-pressure hydraulics for pressure boosting, reverse osmosis, boiler feed and fire-storage systems.
Self-Priming & Rotary Pumps
Instant-priming pumps for tankering, agriculture and dosing of viscous media with unique reliability.
Solving the pain points of industrial pumping
Ongoing dialogue with OEMs, plant engineers and operators drives every revision of our hydraulics.
Computational blade geometry and polished hydraulic channels push the operating point to above 87% BEP flow across a broad band of duties.
An external flush line, silicon-carbide faces and hardened shaft sleeve offer a dramatic reduction in seal replacement downtime.
Low NPSHr impeller inlets and finite-element analysis support stable performance in elevated temperatures and low suction conditions.
Modular wet-end design, worldwide spare-part stocking and quick-access service kits reduce unscheduled stops to the absolute minimum.
