pionEEring
By implementing a large modulation range in connection with very small injection amounts in the lower load
point the Mdp enables innovative burner solutions for modern condensing boilers.
the new concept of the motor-pump combination with integrated drive electronics improves the comfort during
installation, operation and maintenance.
EconoMical
the exact dosing of the fuel enables the reliable operation of the burner with little air surplus, which increases the
efficiency of the heating system.
during full load operation the pump requires less than 60 w of electrical energy thanks to its energy-saving
magnetic drive and the low circulation rate of the fuel at low pressure.
rEliaBlE
the automatic ventilation of the fuel ensures consistent fuel injection without interruptions. this is a definite
advantage when using the Mdp in a Blue flame burner, particularly for small firing capacities.
nozzle tolerances and depositions are automatically compensated by moving the dosing function into the pump.
roBUSt
the pump functions thanks to its design virtually wear-free and thus enables a long lifespan.
due to the permanent automatic ventilation the pump is very robust against air incorporation in inadequately
installed oil systems. therefore, it can be connected to existing oil supply systems without hesitation. Even the dry
suction of fuel is permitted and cannot damage the pump.
QUiEt
Elastomer elements buffer the movement of the pistons before they reach their end positions. this causes less
noise than in an impact without braking. the casing which is isolated from vibration reduces the noise even
further.
EaSily coMBinaBlE
the pump can be used in the burner with pressure atomizing systems common on the market.
the electronic specification of the discharge and the output of the feedback signal after every correctly executed
delivery stroke facilitate the incorporation of the pump in fuel/air control systems.
