From the field

Success Stories

Real projects from energy supply, the steel industry and surface treatment. Every report names the plant, the medium, the problem beforehand and what changed in operation — verifiable rather than claimed.

Plant building of the energy utility housing the exhaust air scrubberEnergy supply · Model TP · size TP50Conveying gypsum slurry under vacuum, reliablyA scrubber running around the clock, a highly abrasive slurry and a reactor held under vacuum: a duty that defeated several pump designs over the years.
HODD Model TP32 with pulsation dampeners feeding the filter press of a tinning lineSteel industry · Model TP · size TP32Feeding a filter press without diaphragm failuresA steel producer fed the membrane filter press of its tinning line with an air-operated diaphragm pump. Recurring diaphragm failures meant a complete spare pump had to be kept in stock at all times.
HODD Model FP20 at the chamber filter press of an electroplating plantSurface treatment · Model FP · size FP20A pump that builds the filtration pressure itselfAn electroplating plant fed its chamber filter press with a progressive cavity pump for many years. It served only as a filling pump — the actual filtration pressure then had to be generated with compressed air.
HODD Model FP in plastic at the chamber filter press of an electroplating plantElectroplating · Model FPReplaced although nothing was brokenThe existing pump was working. The operator replaced it anyway — because a cast iron pump remains a foreign body in a plant that is otherwise built entirely from plastic.
