Standard Chemical Pumps in Exotic Metals SGL Group’s ISO 2858, NFE 4421 and DIN 24256 standard chemical pumps have a proven record of exceptional reliability. All parts in contact with corrosive media are made from exotic metals such as titanium, Hastelloy, nickel alloys or zirconium. This ensures that the pumps are imper vious to liquids and resistant to highly corrosive and thermal stresses, depending on the process conditions and fluids involved. Capacities range from 2 to 3,000 m3/h and discharge heads from 5 to 150 mCL. 2

Besides these standard types, we cater for special requirements and develop pumps which can also be used safely and reliably for more demanding duties. In such cases, we work closely with our customers. Our teams of experts analyze the required liquid transfer and, on this basis, develop solutions which optimally meet their requirements in terms of performance, design and economy.
Titanium pump
1 Impeller
The impeller is assembled by welding massive exotic metal parts together. It is fitted with back vanes for optimum reliability, thus reducing the axial forces on the pump and ensuring a controlled pressure in the seal area. This assembly makes for optimum service conditions.
2 Pump volute
The cast iron or carbon steel external volute of the pump casing is lined with exotic metal sheets (titanium, Hastelloy, nickel alloys or zirconium) to ensure appropriate corrosion resistance.

Impeller Design Open or Closed We offer great flexibility of application in terms of delivered flow rate and discharge head.
Impeller design Closed impellers are designed for the transfer of clean fluids. Pumps equipped with closed impellers make for high discharge heads and good yields. Open impellers are especially suited to the transfer of loaded fluids. Pumps equipped with open impellers make for lower discharge heads and higher flow rates than pumps of the same type fitted with closed impellers. Their yield is lower, owing to the clearance between impeller and casing.
