what is the recommended application for DP-6512&DP-9CT2?

The main recommended applications of the DP-6512/DP-9CT2 will be ;

1. Polyurethane Resin

Key benefits of the polyurethane resin;

  • Non-foaming even in contact with water and will not absorb water
  • Penetrates cracks wider than 0.25 mm
  • Shows good adhesion to wet substrates
  • Fast reaction even underwater
  • Fire resistant
  • No agitation of components required beforehand
  • Low odour
  • Environmentally friendly
  • User friendly

Typical ApplicationsĀ of the polyurethane resin;

  • Strata consolidation in mines and tunnels
  • Stabilising of soft rock strata
  • Consolidation of fracture rock, sands and gravels
  • Water stopping in conjunction with other water stopping PU’s and acrylics
  • Rock bolting applications
  • Repair of underwater constructions
  • Repair of concrete cracks

2.Epoxy Resin

Key benefits of the epoxy Resin?

  • Highly flexible > 100% elongation
  • Low viscosity
  • Bonds to damp substrate
  • Good pot life
  • Can be filled if required

Typical ApplicationsĀ of the epoxy resin;

  • Hydro-electric plants
  • Circulating water tunnels
  • Waste water and sewer lines
  • Injection of moving cracks
  • Flexible floor jointing

 

DP-6512/DP-9CT2 is a high pressure, medium volume airless pump with a fixed ratio of 1:1 for automatic mixing systems. It is used in the construction and mining industry for the injection of polyurethane or epoxy injection resins. It is robust and can be easily wheeled onto any site. The DP-6512/DP-9CT2 incorporates a flush pump and flush pump feed line to the mixing head allowing for fast and efficient cleaning of the mixing head between breaks in the injection sequence.

 

Using the Pump

Specific requirements for using the pump depend largely on the type of material being injected and the application. Please consult your local DPAIRLESS representative for more information. Always make sure that the pump is thoroughly cleaned after use.

 

Cleaning the Pump

Flush as much of the material out of the pump as possible by removing the intake hoses from the material. Lift and run the pump until satisfied that all material has been purged from the pump.

  1. Place the intake hoses into a container of Polyurethane Resin Cleaner with the injection hose valve open and pointing into the cleaner to re-circulate the material.
  2. Run the pump under low pressure until the cleaner flows through the injection hose. Continue this for about 1 minute.
  3. Close the injection hose valve and run the pump under low pressure until lock off. This will ensure that the cleaner is forced into all parts of the pump, in particular the pressure gauges, if fitted.
  4. Turn off the air supply and release any built up pressure through the bleed lines. Then carefully open the injection hose valve to release the pressure.

 

Repeat steps 3 and 4 several times until satisfied that the injection material has been purged. Repeat step 1 to clear the pump of the Polyurethane ResinĀ Cleaner and then using fresh cleaner repeat steps 2 to 5 to purge the pump of contaminated cleaner as many times as necessary.

 

At some stage during the cleaning process, flush the bleed valve to keep it clear and operational. When the pump is not in use for any length of time, (particularly overnight), after cleaning, repeat steps 1 to 5 but this time with engine oil. To ready the paint spraying pump for use, repeat steps 1 to 5 using cleaner. Cleaning the pump is extremely important. If it is not done correctly it will seriously impact the effectiveness and working life of the pump. Grit and other solid particles within the pump will score and wear away at the pump parts and eventually stop it from operating.
