DDP servicing overview
This manual includes maintenance information and minor repair procedures of the Digital Displacement
®
Pump DDP096. Performing maintenance and minor repair of Digital Displacement
®
Pumps DDP096
according to the procedures detailed in this manual will not affect your warranty. Any other repair
operation voids the warranty. For more information about the DDP096 service parts, please refer to the
DDP096 Parts Manual.
Performing minor repairs requires the DDP096 pump to be disconnected from the DPC12 controller and
removed from the vehicle/machine. Thoroughly clean the pump before beginning maintenance or repair
activities. Since dirt and contamination are the greatest enemies of any type of hydraulic equipment,
follow cleanliness requirements strictly, especially when changing the system filter and when removing
hoses or plumbing.
When removing hoses or plumbing, add port covers – the port covers shipped with the pump are
appropriate. Do not plug ports with rags, especially the inlet port as any pieces left behind can cause
pump to malfunction.
Safety precautions
Always consider safety precautions before beginning a service procedure. Take the following general
precautions whenever servicing a hydraulic system in addition to other vehicle or machine precautions.
Unintended machine movement
Unintended movement of the machine or mechanism may cause injury to the technician or bystanders.
Secure the machine or disable/disconnect the mechanism while servicing to protect against unintended
movement.
Flammable cleaning solvents
Some cleaning solvents are flammable.
Do not use cleaning solvents in an area where a source of ignition may be present to avoid possible fire.
Fluid under high pressure
Escaping hydraulic fluid under pressure can have sufficient force to penetrate skin causing serious injury
and/or infection.
Additionally, the fluid may cause burns.
Use caution when dealing with hydraulic fluid under pressure.
Always relieve pressure in the system before removing hoses, fittings, gauges, or other components.
Never use hands or any other body parts to check for leaks in a pressurized component; seek medical
attention immediately if you are cut by hydraulic fluid.
Personal safety
Protect yourself from injury whenever servicing a hydraulic system.
Use proper safety equipment, including safety glasses, at all times.
Hazardous material
Hydraulic fluid contains hazardous material.
Avoid prolonged contact with hydraulic fluid. Always dispose of used hydraulic fluid according to state,
and federal environmental regulations.
