HAMM Hydraulic Pump Dealer and Supplier in West Bengal

West Bengal's road development, industrial expansion, mining-related infrastructure and construction projects require compaction equipment that can operate reliably under demanding site conditions. HAMM Hydraulic Pump Dealer and Supplier in West Bengal specialised machinery for asphalt compaction, soil compaction and earthwork, including tandem rollers, soil compactors and pneumatic-tyre rollers.

When a HAMM machine experiences hydraulic performance problems, selecting a replacement pump requires accurate component identification. Pump displacement, control type, mounting arrangement, shaft configuration and the hydraulic circuit all influence compatibility. Multitech India assists customers with hydraulic pump identification, replacement sourcing, repair evaluation and related spare-parts requirements.

HAMM Hydraulic Pump Dealer and Supplier in West Bengal for Replacement Needs

Construction companies operating around Kolkata and Howrah may require hydraulic pumps for HAMM tandem rollers, soil compactors and other compaction equipment. Before purchasing a replacement, buyers should collect the complete pump identification code and the machine's serial number.

A photograph of the existing pump can help establish the manufacturer, model family and configuration. This is especially useful when the original component has been repaired previously or when the machine has been in service for many years.

Multitech India helps customers evaluate their requirements before selecting a replacement. The objective is to match the hydraulic component to the actual machine rather than relying only on a general model description.

HAMM Hydraulic Pump Supplier for Road Construction Machinery

HAMM Hydraulic Pump Dealer and Supplier in West Bengal For contractors working in Durgapur and Asansol, reliable compaction machinery is important for road construction, industrial development and infrastructure maintenance. HAMM offers different roller configurations for asphalt and earthwork, with hydraulic systems performing functions associated with travel, vibration, steering and auxiliary operations.

The correct pump depends on which circuit requires attention. A travel-drive pump and a vibration-related hydraulic unit may have different operating requirements, even when installed in machines belonging to the same broad family.

Before ordering, customers should confirm the machine generation, pump manufacturer's code, displacement and control arrangement. This process can reduce the risk of receiving a component that requires unsuitable modifications during installation.

HAMM Hydraulic Pump Models and Machine Compatibility

Customers in Siliguri and Kharagpur may operate HAMM equipment from different production periods. The machine series helps identify the equipment category, but it does not automatically identify the hydraulic pump installed in that machine.

Common HAMM machine families include:

• HD series: HD 8, HD 9, HD 10, HD 11, HD 12, HD 13 and HD 14.

• Larger HD rollers: 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 series: HC 50i, HC 70i, HC 100i, HC 110i, HC 119i, HC 130i, HC 140i, HC 160i, HC 180i, HC 200i and HC 250i.

• HP series: HP 180, HP 180i, HP 190i, HP 200i, HP 210i, HP 220i, HP 230i, HP 240i, HP 250i and HP 280i.

These are machine designations, not hydraulic pump part numbers. The installed pump must be verified separately against the machine's specifications and identification plate.

HAMM Hydraulic Pump Models for Documented Applications

Equipment owners around Bardhaman and Haldia may need to identify hydraulic pumps used in older HAMM machines. Documented Bosch Rexroth applications include several A10VG and A4VG variable-displacement pump families.

The following are useful pump references for identification:

• A10VG18 — documented for HAMM HD 8-10C / H1.70.

• A10VG28 — documented in a HAMM pump application.

• A10VG45 — documented in a 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 references are not universal fitments for every HAMM machine. The complete part number, machine serial information and hydraulic configuration should be checked before confirming a replacement.

HAMM Hydraulic Pump Replacement for HC Soil Compactors

Industrial and earthwork operations around Baharampur and Malda may require soil-compaction machinery capable of maintaining consistent performance over long working periods. HAMM's HC family includes different machine sizes and drum configurations for soil compaction.

When an HC machine develops slow response, weak travel or inconsistent operation, the hydraulic system should be assessed methodically. Potential causes include pump wear, contamination, incorrect oil viscosity, restricted filtration, charge-pressure problems or faults in connected valves and controls.

A pump replacement should follow diagnosis rather than being based solely on symptoms. Checking the original pump identification and the condition of the surrounding hydraulic circuit can help determine whether repair or replacement is the more appropriate option.

HAMM Hydraulic Pump Supplier for Pneumatic-Tyre Rollers

For equipment fleets around Jalpaiguri and Cooch Behar, pneumatic-tyre rollers may be used in asphalt and earthwork applications. HAMM's HP family includes different operating-weight configurations designed for compaction tasks where tyre contact and load distribution are important.

Relevant machine designations include HP 180, HP 180i, HP 190i, HP 200i, HP 210i, HP 220i, HP 230i, HP 240, HP 240i, HP 250i, HP 280 and HP 280i.

The hydraulic pump fitted to an individual machine can vary according to the production version and circuit specification. Buyers should therefore provide the complete machine model and pump code before selecting a replacement.

HAMM Hydraulic Pump Service for Travel and Vibration Systems

Contractors operating in Bankura and Purulia may encounter hydraulic problems during demanding compaction work. Common warning signs include unusual pump noise, overheating, pressure fluctuations, reduced travel performance and weak vibration response.

These symptoms can arise from several causes. A worn pump may contribute to pressure loss, but a blocked filter, damaged coupling, control-valve fault or inadequate charge pressure can also affect system performance.

A suitable assessment should consider operating pressure, oil condition, filtration, pump controls and related hydraulic components. Identifying the source of the problem before installing a replacement helps reduce the risk of repeat failure.

HAMM Hydraulic Pump Identification for Older Equipment

Customers in Krishnanagar and Ranaghat may maintain older HAMM machines whose original hydraulic specifications are not immediately available. Historical machine designations found in HAMM-related pump references include 3410, 3412, 3412 P, D12, H207, E3-412 and H202/S400.

Examples of documented 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 help narrow down the identification process, but the installed pump code should always be checked. Previous repairs or component replacements may mean that the existing configuration differs from the original factory arrangement.

HAMM Hydraulic Pump Replacement for Combined Pump Assemblies

For industrial customers around Kalyani and Uluberia, certain older HAMM applications may require attention to combined or double-pump arrangements. These assemblies can contain pump sections with different displacements or hydraulic functions.

Documented examples include the A10VG45 combined with A10VG28, the A4VG71 combined with A22VG45, and the A20VLO190 combined with A4VG56. When evaluating such equipment, the complete assembly and individual pump sections should be identified before procurement.

Ordering a component based only on a partial model number can create problems with displacement, control settings, mounting and circuit compatibility. A clear nameplate photograph and the original part reference are therefore valuable.

HAMM Hydraulic Pump Supplier for Modern Compaction Technology

Construction fleets in Midnapore and Contai may include modern HAMM rollers with integrated electronic and hydraulic controls. Depending on the model, these systems coordinate travel, vibration and other machine functions to support consistent compaction performance.

Some HAMM HD+ machines offer vibration and oscillation configurations, while applicable hybrid models use hydraulic drive technology and a hydraulic accumulator to provide additional power during certain peak-load conditions.

Such differences matter when selecting replacement components. The correct pump must match the machine's particular hydraulic system, rather than simply fitting a general HAMM series designation.

HAMM Hydraulic Pump Sourcing for West Bengal Contractors

For contractors operating around Raiganj and Balurghat, keeping accurate equipment records can simplify future pump replacement. Each machine record should include the machine model, serial number, pump manufacturer, complete pump code, displacement and photographs of the installed component.

This information is particularly helpful when a fleet contains multiple generations of HAMM rollers. It allows technicians and suppliers to distinguish between different pump families and reduces reliance on visual similarity alone.

Multitech India assists customers with hydraulic pump identification, replacement sourcing, repair evaluation and spare-parts requirements for construction equipment.

HAMM Hydraulic Pump Identification Case Study

A contractor maintaining a HAMM roller near Bolpur and Rampurhat noticed that the machine's travel response had become inconsistent during regular site operations. The initial requirement was to replace the hydraulic pump, but the machine model alone did not establish which pump configuration was installed.

The maintenance team recorded the pump identification plate and took photographs of the shaft, mounting surface and hydraulic ports. The machine's serial details were then compared with the existing component information. The hydraulic function was also considered to distinguish the travel circuit from other systems.

This structured identification process helped narrow the replacement requirement without assuming that a pump with a similar displacement would necessarily fit. It also highlighted the importance of checking the complete assembly before procurement. For HAMM equipment, retaining photographs and part-number records whenever a pump is removed can make subsequent maintenance decisions more efficient.
