The advanced stamped technology is applied now also in the new OPEN IMPELLER centrifugal pumps having the volute casing as integral part of the pump body. The DWO are pumps extremely versatile: the particular costruction of impeller allows to handle liquids with floating solids; in this case the suitable mechanical seal must be used. Moreover, the special feature at inlet and outlet allows to fit the pumps both to threaded pipes or to flexible pipes.

USES

• Washing of vegetables, meats, fishes.
• Washing and finishing of tins, cables, etc.
• Washing of bottles, jars, cases, etc.
• Industrial dish-washers.
• Painting cisterns cabins.
• Flow irrigation.
• All applications requesting to move charged liquids, including cases when small solids are floating.
• Swimming pool.

MATERIALS

• Pump casing, mechanical seal, back cover and impeller made of stainless steel AISI304.
• Pump shaft made of stainless steel AISI 304
• Std Mechanical seal: ceramic/carbon (siliconcarbide/silicon carbide "HS" version).
