Welcome at the Waldemar Hagemann KG!

Overhaul reduces costs!

Here are some examples of our range:

injection pumps

Renewal of all worn parts such as pump elements, delivery valves, bearings, flyweights, springs, seals.
In the case of large pumps, if possible, pump elements and delivery valves will be reconditioned, to reduce costs.
After repairs: like new!

injector nozzles

Testing for repairability: nozzles with worn spray holes are not repairable!
The valve seat on the nozzle needle and body is ground and lapped. In case of to much pressure-decrease and needle lift , the nozzle needle must be renewed.
After repairs: like new!

pump elements

The barrel bore is honed out and a new plunger, made from approved materials, is tight-fitted. Sealing surfaces are ground and lapped.
After repairs: like new!

delivery valves + valve supports

The sealing surfaces and valve seats are ground and lapped. Opening pressure of pressure-balancing valves is adjusted.
After repairs: like new!

Signs of wear of injection pump, for example:

hunting;
loss of engine power;
thinning of lube oil

Signs of wear of injector nozzles, for example:

high exhaust temperature;
dark smoke;
pinking

Signs of wear of pump elements, for example:

cavitation-wear of the control edges and holes on plunger and barrel;
hence reduce of ignition pressure and loss of power

Signs of wear of delivery valves, for example:

loss of power;
high exhaust temperatures and dark smoke at part load and idle
