Description
The SHO/CO pumps Lowara combine the advantages of an open impeller with those of the AISI 316 stainless steel construction, which is particularly suited for handling moderately aggressive liquids with suspended solids.
The SHO series consists of single stage centrifugal pumps made of pressed AISI 316 stainless steel with open and recessed impeller made of AISI CF8M stainless steel (casted AISI 316).
MARKET SECTORS: CIVIL, INDUSTRIAL.
APPLICATIONS
- Washing of metal parts and/or surface treatment.
- Washing of produce in the packaging industry.
- Food industry washing equipment and syatems.
- Dyeing plant and textile industry.
- Plants for the circulation and transfer of moderately viscous liquids, with light chemical aggressiveness.
- Industrial washing machines and commercial dishwashers.
