ES
ES(G) pump for gravel and dredging application.
Application

The ES and ESG series gravel pumps feature a horizontal, single-casing centrifugal design with cassette connections and wide flow channels and wear-resistant wet-end parts (hard nickel/high-chrome alloys). Their 360° adjustable discharge orientation enables flexible installation, while offering excellent cavitation resistance and abrasion protection.

The ESG pump is specifically designed for high-head applications.

Structure
Pump Features

Sand pumps are specifically designed for continuous transport of ultra-abrasive slurries with wide particle size distributions.

The ES pump is primarily recommended for: Suction hopper dredging; Dredging barge loading; Reclamation projects. It is also used for transporting heavy-media mixtures in coal washing plants. The thick wet parts significantly extend service life.

The single-casing design enables compact dimensions and reduced weight, making the pump ideal for confined vessel spaces.

The ESG and ESGP pumps are optimized versions of the ES series, which are designed to meet the requirements of multi-stage pump operation in demanding working conditions.
