:: New Froth Pumping Solution GIW Announces HVF Pump

GIW Industries, a leader in the design, manufacture and application of heavy-duty, centrifugal slurry pumps, announces the launch of its new High Volume Froth (HVF) pump. Unlike any other pump on the market, GIW's HVF pump can pump froth without airlocking. The HVF provides continuous operation without shutdown or operator intervention. The new hydraulic design actually removes air from the impeller eye while the pump is running, so you can keep your process moving and improve efficiency.

The GIW HVF can be retrofit into many existing froth applications. The pump's de-aeration system includes a GIW patent-pending vented impeller and airlock venting. This helps to eliminate sump overflow due to pump airlock; reduce downtime; and allow water use to be restricted to the bare minimum. Fewer pumps are required for less capital expense, requiring less water and power usage.

GIW's HVF pump has been fully tested on froth and viscous liquids. The pump exceeded expectations at a large phosphate company in Finland. The company's existing pumps were not able to provide the required flow and were airlocking at only 1/3 process design capacity. After installing GIW's HVF pump, the company achieved a flow of 415 m3/hr. The result? A very satisfied customer.

Designed for air-entrained slurries, the pump can be used in phosphate mining, hard rock mining and oil sands. The pump offers improved efficiency and is environmentally friendly and cost-effective.
