Danfoss

Danfoss makes hydraulics, drives, refrigeration controls and heating products, so a request for "a Danfoss part" could mean an orbital motor on a sweeper or a thermostatic valve on a radiator. Naming the product family is the fastest way to a quote.

Our work sits in Danfoss Power Solutions: orbital motors, proportional and directional valves, pumps and steering units. These are the components that move machinery, and they are what U.S. plants and machine builders ask us to source.

Orbital motors are the volume item. They are low-speed, high-torque motors built around a gerotor or geroler element, and they drive conveyors, augers, winches, sweepers and steering. The OMP, OMR and OMH families cover most of the range, with OMS and OMT above them and the newer Orbital X generation raising torque capacity again.

The code number on the nameplate is the whole specification. Displacement, shaft type and size, port configuration, mounting flange and options are all encoded in one string, which is why two motors that look identical on a bench can be functionally different. Send the code exactly as printed and we can quote without a conversation about dimensions.

On the valve side, the PVG range is modular. Inlet, work and end sections bolt together so a bank is built to the machine's exact function count, with pressure compensation keeping each section's speed steady as load changes and load-sensing holding pump pressure only slightly above the highest demand. That is where the efficiency comes from, and it is also why a replacement section has to match the bank it joins.

Motors fail in a predictable order. Shaft seals go first, usually after contamination has been through the circuit, then the internal wear pair. A seal kit fitted early is a fraction of the cost of a motor, so it is worth looking at the fluid before assuming the motor is finished.

We source Danfoss Power Solutions components and seal kits for North American machine builders and maintenance teams. Send the code number, or the displacement, shaft, porting and mounting, and we will quote availability and lead time.
