ESSCO Horizontal & Vertical Vortex Impeller Pumps

ESSCO manufactures heavy duty solids handling pumps designed to handle large solids & abrasive slurry applications.  The hardened wet-end components allow for heavy abrasives.  The 100% recessed vortex impeller allows for large solids passage without clogging.  These engineered pumps are heavily used in the wastewater & mining markets.

Impeller Designs

Standard 100% Recessed Vortex Impeller Ring Cup Impeller Cup Impeller

Standard 100% recessed vortex impellers can be trimmed in any material. Cast iron, ductile iron, stainless steel, duplex stainless steel, Ni-Hard, HCI (High Chrome Iron) plus many many more.

Ring cup impellers are used in various applications but, are primarily used in grit , slurry or sludge applications. The outside diameter encompasses a ring which is part of the impeller shroud to keep particle impact to a minimum on the pump case. These impellers are available in the same materials as the standard vortex impellers.

Cup style impellers are used in grit and slurry applications with high particle content. Originally developed for the waste water grit handling market this design has found acceptance in handling sludge as well. This design is available in Ni-Hard and HCI as standard materials with Brinnell hardness ranging from 550 (as cast) up to 750. These impellers typically cannot be trimmed. Other materials can be furnished upon request.
