Andhra Pradesh's port infrastructure, highway development, industrial corridors, mining activities and urban construction projects require dependable compaction machinery. HAMM manufactures road rollers and compactors for asphalt construction, earthwork and soil preparation. Its equipment portfolio includes tandem rollers, soil compactors and pneumatic-tyre rollers designed for different working conditions.

HAMM Hydraulic Pump Dealer and Supplier in Andhra Pradesh are important to the operation of these machines, supporting hydrostatic travel and other hydraulic functions. When a pump needs attention, the replacement must be matched to the original component's displacement, control configuration, shaft, mounting and hydraulic application. Multitech India assists construction companies, equipment owners and repair workshops with pump identification, replacement sourcing and repair evaluation.

HAMM Hydraulic Pump Dealer and Supplier in Andhra Pradesh for Construction Equipment

Contractors operating around Vijayawada and Visakhapatnam may require replacement hydraulic pumps for HAMM rollers used in infrastructure and industrial projects. The first step is to identify the precise pump installed in the machine.

Customers should provide the complete HAMM machine model, serial number and existing pump code. Clear photographs of the identification plate, mounting face, shaft and hydraulic ports can help establish the correct specification.

A machine's series name alone may not identify the pump because different production versions can use different hydraulic configurations. Multitech India assists buyers with checking the available technical information before selecting a replacement.

HAMM Hydraulic Pump Supplier for Highway and Asphalt Projects

For construction companies working around Guntur and Nellore, HAMM rollers can support asphalt compaction and road-surface preparation. Different machine configurations are designed for different operating weights and compaction requirements.

The hydraulic pump must be selected according to the function it performs. A pump serving the travel drive may have different operating characteristics from one associated with vibration or another hydraulic circuit.

Before procurement, the original pump code, displacement, control type and mounting arrangement should be checked. This makes the replacement process more reliable and helps avoid unnecessary modifications during installation.

HAMM Hydraulic Pump Models and Machine Compatibility

Equipment owners in Kurnool and Rajahmundry may operate HAMM machinery from different production generations. Identifying the machine family helps establish the equipment category, but the hydraulic pump requires separate verification.

Examples of HAMM machine designations include:

HD compact rollers: HD 8, HD 9, HD 10, HD 11, HD 12, HD 13 and HD 14.

Larger HD machines: HD 70, HD 75, HD 90, HD 100, HD 110, HD 120, HD 130 and HD 140.

HD+ series: HD+ 70i, HD+ 80i, HD+ 90i, HD+ 90i PH, HD+ 100, HD+ 110i, HD+ 120i and HD+ 140i.

HC soil compactors: HC 50i, HC 70i, HC 100i, HC 110i, HC 119i, HC 130i, HC 140i, HC 160i, HC 180i, HC 200i and HC 250i.

HP pneumatic-tyre rollers: HP 180, HP 180i, HP 190i, HP 200i, HP 210i, HP 220i, HP 230i, HP 240i, HP 250i and HP 280i.

These are examples of HAMM machine families, not hydraulic pump part numbers. The actual pump must be identified from the installed component and machine specifications.

Documented HAMM Hydraulic Pump Models for Replacement

For equipment workshops around Tirupati and Anantapur, documented Bosch Rexroth pump applications can help narrow down the identification of older HAMM hydraulic systems.

Important pump references include:

A10VG18 — documented for HAMM HD 8-10C / H1.70.
A10VG28 — documented HAMM pump application.
A10VG45 — documented HAMM pump application.
A10VG45 + A10VG28 — double variable-pump arrangement associated with HAMM 70-75 / HD 70-75.
A4VG40 — documented HAMM applications.
A4VG56 — associated with HAMM 3412 / 3412 P.
A4VG71 — documented across multiple HAMM applications.
A4VG90 — documented HAMM applications.
A4VG105 — associated with HAMM H202 / S400.
A22VG45 — documented HAMM application.
A20VLO190 + A4VG56 — documented combined pump arrangement.
A4VG71 + A22VG45 — documented double variable-pump arrangement.

These are documented pump families and application references, not universal fitments for every HAMM machine. The full pump code and machine configuration should be checked before confirming a replacement.

HAMM Hydraulic Pump Replacement for HC Soil Compactors

For earthwork contractors around Kadapa and Chittoor, HAMM HC soil compactors may be relevant to road foundations, embankment preparation and other compaction activities. The HC family includes different operating weights and drum configurations.

If an HC machine develops reduced travel performance, slow response, overheating or inconsistent operation, the complete hydraulic circuit should be examined. Pump wear is one possible cause, but contaminated oil, restricted filtration, charge-pressure problems and control-valve faults can also affect performance.

A proper inspection helps determine whether repair, rebuilding or replacement is appropriate. Evaluating the surrounding hydraulic system before installing another pump can also reduce the possibility of repeat failure.

HAMM Hydraulic Pump Supplier for Pneumatic-Tyre Rollers

Customers working around Ongole and Eluru may require hydraulic components for HAMM pneumatic-tyre rollers used in asphalt and earthwork projects. The HP family includes different machine sizes and configurations for various compaction requirements.

Relevant machine designations include:

HP 180 and HP 180i
HP 190i and HP 200i
HP 210i and HP 220i
HP 230i and HP 240
HP 240i and HP 250i
HP 280 and HP 280i

The pump fitted to an individual machine may vary according to its production version and hydraulic circuit. Buyers should verify the original pump identification rather than relying only on the HP model designation.

HAMM Hydraulic Pump Identification for Older Machines

For equipment owners around Srikakulam and Vizianagaram, older HAMM machinery may require identification through historical model references. HAMM-related pump documentation includes machine designations such as 3410, 3412, 3412 P, D12, H207, E3-412 and H202/S400.

Documented pump associations include:

A4VG56: HAMM 3412 / 3412 P.
A4VG71: HAMM D12 / H207 / HD120 / HD140.
A4VG71: HAMM E3-412.
A4VG105: HAMM H202 / S400.
A10VG18: HAMM HD 8-10C / H1.70.

These historical references can narrow down the possible pump family, but the actual installed pump code must be verified. Previous repairs or modifications may have changed the machine's original hydraulic configuration.

HAMM Hydraulic Pump Service for Travel and Vibration Circuits

For maintenance teams around Machilipatnam and Kakinada, hydraulic pump problems may become visible through abnormal noise, overheating, pressure fluctuations, weak travel response or inconsistent vibration.

These symptoms do not necessarily mean that the pump alone has failed. Contaminated hydraulic oil, restricted filters, inadequate charge pressure, damaged couplings and control-valve faults can also cause performance problems.

A proper diagnostic process should include pressure checks, oil-condition inspection and examination of the connected hydraulic circuit. This helps establish the cause before deciding whether repair or replacement is necessary.

HAMM Hydraulic Pump Replacement for Combined Assemblies

For workshops serving Tenali and Hindupur, certain older HAMM machines may require identification of double-pump or combined hydraulic assemblies. These arrangements can include separate pump sections with different displacements and functions.

Documented examples include:

A10VG45 + A10VG28 double variable-pump arrangement.
A4VG71 + A22VG45 double variable-pump arrangement.
A20VLO190 + A4VG56 documented combined pump arrangement.

The complete assembly should be reviewed before ordering individual pump sections. A component with a similar displacement may still be unsuitable if its shaft, mounting, controls or hydraulic connections differ.

HAMM Hydraulic Pump Support for Modern Compaction Technology

Construction companies operating around Proddatur and Madanapalle may encounter modern HAMM rollers with integrated electronic and hydraulic controls. Depending on the model, these systems coordinate travel and compaction functions to maintain the intended operating performance.

Certain HD+ machines offer vibration and oscillation configurations, while applicable hybrid machines use hydraulic-drive technology and an accumulator to provide additional power during selected peak-load conditions.

These differences make exact machine identification important. A replacement pump should be selected according to the specific hydraulic configuration rather than simply matching a general machine-family name.

HAMM Hydraulic Pump Procurement for Andhra Pradesh Equipment Fleets

For equipment workshops around Nandyal and Adoni, maintaining an individual hydraulic component record for each HAMM machine can simplify future procurement. Useful information includes the machine model, serial number, pump manufacturer, complete pump code, displacement and photographs of the installed unit.

This record can help distinguish between travel pumps, vibration-related components and auxiliary hydraulic units. It is especially useful for fleets that maintain machines from different production generations.

Multitech India assists customers with pump identification, replacement sourcing, repair evaluation and related spare-parts requirements.

HAMM Hydraulic Pump Identification Case Study

A contractor operating a HAMM roller near Amalapuram and Tadepalligudem noticed inconsistent travel performance during regular site operations. The initial requirement was to source a replacement pump, but the machine's model designation alone did not establish the exact hydraulic specification.

The existing pump's identification plate was photographed, and the shaft, mounting surface and hydraulic ports were documented. The machine serial information was then considered alongside the pump details. The hydraulic function was also reviewed to distinguish the travel circuit from other systems.

Instead of choosing a replacement solely by approximate displacement, the identification process focused on the original component code and configuration. This provided a more reliable basis for checking compatibility and evaluating the replacement requirement.

The practical lesson is to preserve the complete pump identification whenever a hydraulic unit is removed. The machine serial number, pump code and clear photographs can reduce uncertainty during future procurement and maintenance.
