Swirl-Type Gas-Solid-Liquid Mixed-Flow Pump

Hydraulic Design: Features a vortex-type hydraulic system specifically engineered for conveying high solids content and long fibers. The impeller is concealed at the rear, creating a spacious flow passage to ensure clog-free operation. Wear on hydraulic components has minimal impact on performance.
Gentle Conveyance: Most solids are discharged directly through the pump inlet under the centrifugal force generated by the impeller’s vortex rotation, bypassing the impeller passages. This minimizes damage to conveyed solids while reducing wear on the impeller and pump casing flow surfaces, extending service life.
Bearing Housing: Designed per API 610 standards with thin-oil lubrication. Features auxiliary vanes on the impeller to balance axial forces, ensuring overall structural rigidity, shaft stiffness, and strength to meet high reliability requirements.
Shaft Seal Configuration: Utilizes a cartridge mechanical seal conforming to API 682 standard dimensions with a corresponding seal flushing system. The standard Plan 32 flushing scheme is adopted. The internal clearance formed by the throat bushing prevents solid ingress into the seal chamber while reducing seal flushing water consumption. This design offers high reliability and convenient maintenance.
