Broad Hydraulic Versatility through a series of impeller design options enables better hydraulic fit for each application. The result is lower energy consumption and operating costs.

Double Suction First Stage Impeller reduces NPSHR and meets Hydraulic Institute standards for suction-specific speed. This design means a shorter, more rigid pump, providing freedom from cavitation over a wide operating range.

Double Volute Design minimizes radial loads, extending bearing life.

Suction Can creates optimal hydraulic conditions through the suction flange inlet into the suction bell.

Rigid, Adjustable Flanged Coupling maintains accurate pump-motor alignment, provides proper impeller clearance adjustment and facilitates seal maintenance.
