These references should not be interpreted as a universal fitment list. The correct replacement depends on the complete ordering code, machine serial number, displacement, rotation, control arrangement, shaft and mounting specifications. HAMM designations such as HD, HD+, HC, DV, DV+ and HP refer to machine families, not hydraulic pump model numbers. Hydraulic motors must also be distinguished from hydraulic pumps.
HAMM Road Roller and Soil Compactor Machine Applications
HAMM manufactures tandem rollers, articulated tandem rollers, pneumatic tyre rollers and soil compactors. Each category performs a different compaction function and may use a different hydraulic configuration.
The HD and HD+ families include tandem roller applications, while DV and DV+ identify additional roller configurations. HC machines are soil compactors, and HP machines are pneumatic tyre rollers. Hydraulic pump specifications can vary between machine categories and production generations.
Multitech India can assist with hydraulic pump enquiries for older and newer HAMM machinery, subject to verification of the installed assembly and original equipment specification.

A Practical HAMM Hydraulic Pump Identification Case
A construction contractor reported that a HAMM roller had developed inconsistent vibration and reduced hydraulic response during a road-compaction assignment. The maintenance team initially considered replacing the complete pump assembly, but the actual cause of the problem had not been confirmed.
The technicians first checked hydraulic oil condition, filters, suction connections and visible hoses. They then recorded the machine serial number and photographed the installed pump nameplate. These details helped distinguish the existing hydraulic configuration from other pump assemblies with similar external dimensions.
The example highlights the importance of technical identification before procurement. A machine brand and model alone may not provide sufficient information to select a suitable replacement. The complete pump code, control arrangement and original hydraulic specification should be verified to reduce the possibility of incorrect supply and repeated downtime.
