HAMM Hydraulic Pump Dealer and Supplier in Bihar

HAMM Hydraulic Pump Dealer and Supplier in Bihar is widely associated with road construction, asphalt compaction, earthwork and soil compaction. Its product range includes articulated and pivot-steered tandem rollers, soil compactors and pneumatic-tyre rollers. HAMM’s current range includes HD, HD+, HX, HC and HP families, covering machines from compact construction equipment to heavy soil compactors.

For contractors, road developers and equipment workshops in Bihar, hydraulic pump replacement should be based on the actual machine and hydraulic circuit rather than simply selecting a pump from the HAMM model name. Pump displacement, control configuration, rotation, mounting, shaft arrangement and the original identification code can all affect compatibility.

HAMM Hydraulic Pump Dealer and Supplier in Bihar for Replacement Requirements

Multitech India supports buyers looking for replacement and service solutions for HAMM hydraulic pumps used in construction and compaction equipment. Customers in Patna and Gaya can share the machine model, serial number, old pump photograph and pump nameplate details before purchasing a replacement.

A correct identification process helps avoid installing a pump with the wrong displacement or control configuration. This becomes especially important for older HAMM machines where the original hydraulic assembly may have been replaced or rebuilt during the machine's service life.

HAMM Hydraulic Pump Supplier for Road Construction Equipment

Road projects around Muzaffarpur and Bhagalpur frequently require dependable compaction equipment for asphalt and earthwork applications. HAMM's product portfolio includes tandem rollers for asphalt construction and soil compactors for earthworks, while HP pneumatic-tyre rollers are designed for earthwork and asphalt applications.

A hydraulic pump supplier should therefore evaluate whether the requirement is related to travel, vibration, steering, auxiliary functions or another hydraulic circuit. Supplying the correct pump assembly can reduce unnecessary modifications during installation.

HAMM Hydraulic Pump Distributor for HD and HD+ Rollers

For equipment operating around Darbhanga and Purnia, HD and HD+ machines can be important parts of road-building fleets. HAMM's range includes HD machines from compact rollers through larger tandem rollers, while the HD+ family extends across several operating-weight classes.

Common machine families that may require hydraulic-pump identification include:

• HD 8, HD 9, HD 10, HD 11, HD 12, HD 13 and HD 14

• HD 70, HD 75, HD 90, HD 100 and HD 110

• HD 120, HD 130 and HD 140

• HD 90i, HD 110i, HD 120i, HD 130i and HD 140i

• HD+ 70i, HD+ 80i, HD+ 90i, HD+ 100, HD+ 110i, HD+ 120i and HD+ 140i

The exact hydraulic pump should still be confirmed from the machine and existing component identification.

HAMM Hydraulic Pump Models Used in Documented Applications

A number of Bosch Rexroth axial-piston pumps are documented for HAMM applications. Available parts references identify A10VG and A4VG pump families on different HAMM machines. For example, A10VG18 is documented for the HAMM HD 8-10C/H1.70, while A4VG71 is documented as a travel pump for D12, H207, HD120 and HD140.

Important documented pump references include:

• A10VG18 — HAMM HD 8-10C / H1.70

• A10VG28 — documented HAMM hydraulic pump application

• A10VG45 — documented HAMM hydraulic pump application

• A10VG45 + A10VG28 — double variable-pump arrangement for HAMM 70-75 / HD 70-75

• A4VG40 — documented HAMM applications

• A4VG56 — HAMM 3412 / 3412 P

• A4VG71 — several HAMM applications including D12, H207, HD120 and HD140

• A4VG90 — documented HAMM applications

• A4VG105 — HAMM H202 / S400

• A22VG45 — documented HAMM application

• A20VLO190 + A4VG56 — documented HAMM pump arrangement

• A4VG71 + A22VG45 — documented double variable-pump arrangement

These are documented pump families and references, not a claim that every listed pump fits every HAMM machine. The complete pump code is essential when ordering a replacement.

HAMM Hydraulic Pump Dealer for HC Soil Compactors

In Bihar Sharif and Ara, HAMM HC soil compactors can be used for demanding earthwork and soil-compaction requirements. HAMM's current range includes HC CompactLine machines and larger HC compactors, with machines available across different weight and drum configurations.

Relevant HAMM machine families include:

• HC 50i and HC 70i

• HC 100i, HC 110 and HC 110i

• HC 119, HC 119i and HC 119i D

• HC 120i and HC 129

• HC 130 and HC 130i

• HC 139i, HC 139i D and HC 140i

• HC 160, HC 160i, HC 180 and HC 180i

• HC 200, HC 200i, HC 250 and HC 250i

Current HAMM machines use electronic machine-management functions, and the hydraulic system can be closely integrated with machine drive and vibration functions. HAMM states that HAMMTRONIC regulates functions including drive torque distribution and the hydrostatic vibration drive.

HAMM Hydraulic Pump Replacement for HP and Other Machines

Customers in Sasaram and Dehri may require pump identification for pneumatic-tyre rollers and older HAMM equipment. The HP series is designed for earthwork and asphalt construction, with flexible ballasting used to adjust machine weight and wheel load.

HAMM HP machine references include:

• HP 180

• HP 180i

• HP 190i

• HP 200i

• HP 210i

• HP 220i

• HP 230i

• HP 240

• HP 240i

• HP 250i

• HP 280

• HP 280i

For older machines, the pump identification plate is particularly valuable because a machine model can have different pump configurations depending on production year and hydraulic-system specification.

HAMM Hydraulic Pump Service and Identification Support

Equipment owners in Begusarai and Katihar can simplify the replacement process by providing clear photographs of the existing pump. A useful identification package normally includes the complete model/code, serial information, mounting-side photograph, shaft-end photograph and hydraulic-port arrangement.

For Bosch Rexroth pumps, the difference between families such as A10VG and A4VG is significant. Even within the same family, displacement and control versions can vary. For example, documented HAMM references include A4VG40, A4VG56, A4VG71 and A4VG90 variants.

HAMM Hydraulic Pump Support for Bihar Construction Fleets

Projects around Chhapra and Hajipur can involve multiple generations of compaction equipment. A workshop may therefore have one modern HD+ roller alongside older HD or HC equipment. This makes component identification more important than ordering a pump solely from a machine-series name.

For newer HAMM equipment, model identification should be combined with the machine serial number and hydraulic component data. For older equipment, the original pump code can provide a more reliable starting point for sourcing a replacement or rebuilding an existing unit.

HAMM Hydraulic Pump Repair and Replacement in Bihar

In Motihari and Bettiah, hydraulic pump problems can become visible through weak travel performance, abnormal noise, pressure instability, overheating, slow response or inconsistent vibration performance. These symptoms do not automatically prove that the pump itself has failed, because contamination, charge pressure, control valves, couplings and other hydraulic components can also contribute.

A proper diagnosis should therefore include pressure testing and inspection of the complete circuit before deciding between pump repair, exchange or replacement. Multitech India can assist buyers with pump identification, replacement requirements, spare-parts evaluation and hydraulic service requirements.

HAMM Hydraulic Pump Models for Older Equipment

For customers in Sitamarhi and Jehanabad, older HAMM equipment may require identification from historical model numbers rather than current machine catalogues. Documented historical applications include HAMM 3410, 3412, 3412 P, D12, H207, E3-412 and H202/S400.

Examples of documented hydraulic pump associations include:

• A4VG56 — HAMM 3412 / 3412 P

• A4VG71 — HAMM E3-412

• A4VG71 — HAMM D12 / H207 / HD120 / HD140

• A4VG105 — HAMM H202 / S400

• A10VG18 — HAMM HD 8-10C / H1.70

The historical machine designation should always be checked against the pump's actual nameplate before procurement.

HAMM Hydraulic Pump Supplier for Modern Compaction Applications

For fleets operating around Madhubani and Samastipur, newer HAMM machines may incorporate more sophisticated electronic control and hydraulic functions. Current HAMM equipment includes HD+, HX, HC and HP series, with different machine configurations for asphalt, earthwork and specialised compaction.

The HD+ 90i PH, for example, uses a hybrid hydraulic drive and hydraulic accumulator to provide additional short-term power during peak-load events such as starting or activating vibration/oscillation.

HAMM Hydraulic Pump Identification Story

A road-construction contractor operating near Buxar and Kishanganj once approached a hydraulic supplier after a HAMM roller developed inconsistent travel performance. The first requirement appeared to be a replacement pump, but the machine model alone was not sufficient for identification.

The existing pump was photographed from several angles and its identification plate was checked carefully. The hydraulic circuit was then considered along with the machine generation and application. Instead of selecting a pump solely because its displacement appeared similar, the complete pump family and configuration were compared.

The inspection also helped distinguish the travel circuit from other hydraulic functions. This avoided ordering an incorrectly configured unit and allowed the replacement requirement to be evaluated more systematically. The lesson for equipment owners was simple: when a HAMM hydraulic pump needs replacement, the complete pump code, machine model and serial information should be considered together. Proper identification can save installation time and reduce the risk of an incompatible replacement.
