HD
HD pumps are suitable for a wide range of industrial applications, including the food, chemical, pharmaceutical, textile, water treatment fields, and more.
These pumps are known for their high efficiency and reliability. The simplicity of construction and component modularity ensure low spare stock and cost-effective operation.
Thanks to the closed impeller, HD pumps are perfect for conveying clean liquids or those with a small amount of suspended solids.

Technical features
➊ 1 casing, 2 impellers
Every size of pumps can use a unique casing that both applies to closed impellers and open impellers (with replaceable wearing plate). This versatility allows the pump to be easily used in new plants and processes.
Pump casings are made by investment casting and they are electrochemically polished.
➋ Standard electric motor
HD-HG pumps motors are unified according to IEC standard type B3B5 (flange/feet execution) and they are easily available on the market.
The pump shaft is fixed on the motor one and it can be easily replaced in case of wear.
➌ Casing design
Casings have high thickness, are made by investment casting and electropolished, thus ensuring low NPSH values and high efficiency.
HD pumps are mainly used in the following sectors
