EHF
EHF
EHF pump for froth slurry transportation.
Application
The EHF(CM) series pump can be widely used in mineral processing, coal washing, metallurgy, and other industries, especially suitable for heavy flotation process and conveying high foam content, high concentration and high viscosity of water, solid, gas three-phase slurry.
Structure
Pump Features

Horizontal foam pumps feature an oversized inlet and semi-open impeller with induced vanes, enabling reliable handling of persistent foam and high-viscosity slurry delivery.

The large suction size & induced vane design improves the pump's NPSH performance, enhances the pump's operational stability, and ensures a longer service life of the wet parts.

The pump's superior defoaming capability and high flow capacity significantly reduce operational workload, simplify maintenance procedures, and enhance production efficiency.

The pump delivers superior operational stability, significantly reducing vibration, noise, and bearing temperature during operation.

Lubrication oil and grease can be used in dual-use bearing chamber, large-diameter, high-strength rotary shaft matching the high performance bearings which bear the axial and radial force, greatly improving the stability of the operation and prolonging the average trouble-free operation time.
