Type DKP

DKP Flow meter mounted Additive Dosing Piston Pumps

These systems are very beneficial in extreme climate conditions and/or in the absence of any electronics.

The metering system comprising the mechanical additive piston pump type DKP is a versatile system used for metering and injection of a wide range of additive products.

Typical applications are anti-icing (aviation market sector) as well as mineral oil performance additives or markers. 

Benefits from its simplicity

  • the metering piston pump is constructed as a separate part and is made of stainless steel and roller bearing steel.
  • DKP injector pumps are direct meter coupled
  • integration requires mechanical expertise only
  • the system is easy to operate via a knob to enable or disable the proportional additive injection into the main stream
  • virtually maintenance free

Application range

  • typical nominal injection ratios are 1000, 2000 and 3000 ppm
  • the DPK injector pumps are available with 1 or 2 cylinder which enable up to 3 injector rates depending the actual cylinder activation
    • 1st cylinder active (first number in model code)
    • 2nd cyclinder active (second number in model code)
    • both cyclinder active
  • nominal pressure capability 10 bar
  • generic low temperature capable
  • NBR 872 gasket compatible fluids and conditions

Typical combinations

The DKP is typically applied to Alfons Haar PD meter type
