Materials of Construction<br />
DÜCHTING PUMPEN High Pressure<br />
Pumps are built in several different<br />
material combinations:<br />
- Cast Iron<br />
- Cast Steel<br />
- Bronze<br />
- Stainless Steel<br />
- DUPLEX Stainless Steel<br />
- Super DUPLEX Stainless Steel<br />
Manufacturing<br />
Superior<br />
performance<br />
and precision is<br />
achieved by using<br />
the latest multiaxis<br />
CNC and balancing<br />
machines.<br />
acc. to ISO 9906-I<br />
Quality Assurance<br />
To ensure highest quality, every<br />
pump is tested and certified on<br />
our test bed according to<br />
international standards.<br />
Precision Casting<br />
Ceramic molds<br />
are used for<br />
impeller and<br />
diffuser castings<br />
so that a smooth<br />
surface is obtained<br />
resulting in<br />
improved hydraulic<br />
performance.<br />

Bearings<br />
Grease or oil-lubricated anitfriction<br />
bearings for long-life<br />
performance.<br />
Suction Chamber<br />
Advanced design for<br />
constant inlet velocities.<br />
Wear Rings<br />
Outstanding<br />
reliability while<br />
minimizing flow<br />
losses.<br />
Diffuser<br />
CFD optimized flow<br />
channels resulting in<br />
reduced impact losses.<br />
Discharge Casing<br />
CFD designed to<br />
achieve optimal<br />
discharge conditions.<br />
Balancing Device<br />
Axial thrust<br />
compensation by<br />
balancing discs or<br />
balancing drums.<br />
Impeller<br />
Optimized design for specific speed.<br />
Cast in ceramic molds for a smooth<br />
surface. Wide range of high efficiencies<br />
achieved by using different impeller sets<br />
for each pump size.<br />
