Three-phase drainage pumps equipped with dual impellers capable of very high heads. Cast iron construction gives exceptional performance in harsh operating conditions. With this design the base is small, which enables good positioning in confined spaces.

The LH-W-series is a three-phase cast iron extra high head drainage pump having dual impellers. Installations in narrow spaces like deep wells are no problem thanks to its slim design. The center flange construction assures a stable installation even if it is fixed by the discharge pipe.*1 The top discharge, flow-thru design provides maximum motor cooling efficiency allowing continuous operation at low water levels and extended dry-run capability. The pump incorporates seal pressure relief ports that prevent the pumping pressure from applying to the shaft seal.*2

Ash from the recycling process is stored on the premises of a steel recycling company. Recycled water is used to cool the ash. This drainage water must be sprayed in large quantities onto the hot ash via a sprinkler system. The sprinkler system itself operates at a system pressure of 3 to 4 bar.
