Horizontal Pumps
Horizontal split-case pumps for large-flow water supply and infrastructure duty.
Technical data sheet
Horizontal Split-Case Pump
Horizontal axially-split casing centrifugal pump engineered for high-flow water transfer in municipal, fire-fighting (UL/FM ready), HVAC chilled water, and industrial cooling duties. Double-suction impeller for low NPSH and balanced axial thrust.
