|
 |
|
| Centrifugal Pumps are the most common and well-established pumps on the market. They come in many different models and can transfer fluids with high efficiency over a wide range of flows and pressures. |
|
| The pumps of the HD-HDA series are close-coupled centrifugal pumps with closed impeller suitable to convey either clear liquids or liquids containing a small percentage of solids in suspension. This series of pump together with the HG (open impeller) and RS (vortex) versions were designed to meet difficult applications needs with reduced costs. |
|
|
| These pumps have the same dimensions as DIN 24256 series. The pumps simple and modular design together with their versatility of use are at the basis of the huge success of this series. All available models can be equipped with different kinds of seals: single, double, back to back, flushed, cooled, or gland packing. |
