CHEMCOS CERAMIC COATINGS OFFERS EFFICIENCY INCREASE

10/01/2017 10:00

After many years utilising other ceramic systems, KDHC were searching for a new system which could improve the efficiency of their hot and cold water pumps.

KDHC were looking for a minimum 5% reduction in overall energy consumption. The chosen system would then be specified to coat all of their pumps. The hot water pump coating also had to be able to withstand temperatures up to 100°C.

    
Original Condition

Both the hot and cold water pumps were grit blasted to Sa 2½, before localised areas affected by pitting damage were filled using specialised metal repair putties.

    
After Surface Preparation

The hot water pumps received two coats of Hot-cote™ RF 900 and the cold water pumps received two coats of Ceram-chem™ RP 500.

    
Completed Application

Please find the outcome of the testing in the table below:

  Hot Water Pump
  Before After Change
Power (kW) 324.94 298.21 -8.2%
Flow (m3/hr) 1,108.13 1,296.89 +17.0%
Efficiency (%) 45.5 61.8 +16.3%
  Cold Water Pump
  Before After Change
Power (kW) 443.49 419.54 -5.4%
Flow (m3/hr) 3,173.06  3,520.0  +10.9%
Efficiency (%) 56.4 72.1 +15.7%

By utilising the Chemco technology, the overall energy consumption had decreased by the required percentage whilst the efficiency had increased by +16.3% and +15.7% respectively.

All hot and cold water pumps under the control of KDHC will now be coated using Chemco's solvent-free ceramic coating technology.

The following benefits can be achieved by utilising these coating systems:

  • Solvent-free
  • Significantly increased pump efficiencies
  • Energy consumption substantially reduced
  • High temperature resistance (up to 210°C)
  • Hardwearing ceramic coatings with excellent abrasion and impact resistance
