HAMM Hydraulic Pump Dealer and Supplier in Karnataka

HAMM road rollers and compactors depend on hydraulic systems for hydrostatic travel, vibration, steering and other machine functions. Customers looking for replacement hydraulic pumps need to match the pump with the exact machine model, serial number, hydraulic circuit and original pump identification. Multitech India supports HAMM Hydraulic Pump Dealer and Supplier in Karnataka enquiries for HAMM equipment across Karnataka, including replacement, sourcing and identification requirements.

For customers in Bengaluru and Mysuru, the machine model and pump nameplate can be used to identify the required hydraulic unit before a quotation is prepared. A clear photograph of the original pump can also help establish the manufacturer, displacement and control configuration.

HAMM Hydraulic Pump Dealer and Supplier in Karnataka

Multitech India supplies and sources hydraulic pumps and related components for HAMM rollers and compactors. The requirement may involve a hydrostatic travel pump, vibration pump, tandem pump, auxiliary hydraulic pump or another hydraulic component.

Customers from Hubballi and Mangaluru can provide the complete HAMM machine designation, serial number and existing pump details. This is particularly important because pumps with similar external dimensions can have different displacement, rotation, control, shaft and mounting specifications.

HAMM Hydraulic Pump Models

HAMM equipment has used hydraulic pumps from established hydraulic-component manufacturers. Depending on the machine generation and hydraulic circuit, documented HAMM applications include Bosch Rexroth A4VG-series and Sauer-Danfoss pump families.

Bosch Rexroth pump models used in documented HAMM applications

• A4VG45

• A4VG56

• A4VG71

• A4VG90

• A4VG105

• A22VG45

• A4VG71 + A22VG45

• A4VG71 + A4VG71, where applicable

Sauer-Danfoss pump models associated with HAMM applications

• 90R055

• 90R075

• 90R100

• PV90R75

• PV90L75

• JRR075

• JRL075

These are hydraulic-pump model designations, while HD, HD+, HC, HX, HP and DV+ are HAMM machine families. They should not be treated as universally interchangeable.

For Belagavi and Davanagere, buyers can send the complete pump code rather than ordering solely by displacement. This helps establish whether the requirement is for the correct control version and hydraulic configuration.

HAMM Hydraulic Pump for HD Series Rollers

HAMM HD tandem rollers use hydraulic systems for propulsion and compaction functions. Different generations of HD machines can use different pump arrangements, making machine identification important when sourcing a replacement.

Customers in Tumakuru and Shivamogga can enquire for HD-series hydraulic pumps by providing the machine plate and original pump photograph. Multitech India can then assess the requirement according to the available identification information.

HAMM HD machine models

• HD 8

• HD 9

• HD 10

• HD 11

• HD 12

• HD 13

• HD 14

A machine model alone does not establish the exact pump part number. The serial range and original hydraulic pump identification remain important.

HAMM Hydraulic Pump for HD+ Rollers

The HD+ series includes modern tandem rollers with electronically managed machine functions. Hydraulic systems support important operations including travel and vibration, with specifications varying between machine configurations.

For Ballari and Kalaburagi, pump enquiries can be checked against the complete HD+ model designation. Providing the suffix and machine serial number is useful when identifying the correct replacement unit.

HAMM HD+ models

• HD+ 70i

• HD+ 80i

• HD+ 90

• HD+ 90i

• HD+ 90i PH

• HD+ 100

• HD+ 110

• HD+ 110i

• HD+ 120

• HD+ 120i

• HD+ 140

• HD+ 140i

The HD+ 90i PH uses HAMM's Power Hybrid technology, so its hydraulic arrangement should be verified against the specific machine rather than assumed to be identical to a conventional tandem roller.

HAMM Hydraulic Pump for HC Soil Compactors

HAMM HC machines are designed for soil-compaction applications. Their hydraulic systems support propulsion, vibration and other machine functions, with pump arrangements depending on the particular generation.

For Vijayapura and Hassan, buyers can provide the HC machine model, serial number and pump nameplate so that the hydraulic requirement can be checked before replacement.

HAMM HC machine models

• HC 50i

• HC 70i

• HC 110

• HC 110i

• HC 119

• HC 119i

• HC 130

• HC 130i

• HC 139i

• HC 139i D

• HC 180

• HC 200

• HC 250

The pump serving the travel circuit may differ from the hydraulic unit serving vibration, so the affected function should be identified before ordering.

HAMM Hydraulic Pump Models for Older Rollers

Older HAMM rollers continue to generate replacement-pump enquiries, particularly where original hydraulic components have experienced wear after extended operation. Documented parts references associate various Bosch Rexroth A4VG pumps with older HAMM equipment.

For Raichur and Bidar, customers with older machines should provide the original pump plate whenever possible. Older pump assemblies can have specifications that differ considerably from later HAMM equipment.

Documented older HAMM pump applications

• HAMM 3410 — A4VG71

• HAMM 3412 / 3412 P — A4VG56

• HAMM E3-412 — A4VG-series applications

• HAMM E3-519 — A4VG90

• HAMM 3516 / 3516 P — A4VG90

• HAMM 3518 / 3518 P — A4VG90

• HAMM 3520 / 3520 P — A4VG90

• HAMM H202 / S400 — A4VG105

• HAMM D12 / H207 / HD120 / HD140 — A4VG71

• HAMM D12 / H207 / HD120 / HD140 — A4VG71 + A22VG45

These references identify documented applications and should not be interpreted as blanket interchangeability specifications.

HAMM Hydraulic Pump for Vibration Systems

Vibration is a fundamental operating function of a HAMM roller. If travel remains normal while vibration becomes weak, intermittent or inconsistent, the problem may involve the vibration hydraulic circuit rather than the propulsion pump.

For Udupi and Chitradurga, Multitech India can assist with identifying whether the requirement involves a vibration pump, travel pump, hydraulic motor, valve or another component.

Common HAMM hydraulic-pump requirements

• Hydrostatic travel pump

• Vibration pump

• Variable-displacement piston pump

• Tandem hydraulic pump

• Double pump assembly

• Auxiliary hydraulic pump

• Steering-related hydraulic pump

• Replacement piston pump

• Hydraulic pump repair

• Hydraulic pump testing

HAMM Hydraulic Pump for Hydrostatic Drive

Hydrostatic drive systems allow HAMM rollers to control travel speed and direction through hydraulic power transmission. A problem in the drive circuit can appear as reduced travel force, inconsistent movement, poor climbing performance or excessive hydraulic temperature.

For Kolar and Mandya, buyers can provide the machine model together with the symptoms and original pump identification. This can help distinguish a possible pump requirement from a hydraulic motor, valve, control or other circuit issue.

HAMM Hydraulic Pump for DV+ and HP Machines

HAMM's product portfolio also includes DV+ tandem rollers and HP pneumatic-tyre rollers. These machines have different operating configurations, so pump selection should be based on the exact model and hydraulic circuit.

For Chikkaballapur and Gadag, customers can mention the full machine designation when requesting a hydraulic-pump quotation.

HAMM machine models beyond HD and HC

• DV+ 90i

• DV+ 110i

HAMM Hydraulic Pump Replacement Requirements

Correct identification is the most important step before purchasing a replacement pump. The pump's displacement is only one part of the specification. Rotation, control type, shaft, mounting and hydraulic circuit must also correspond to the machine.

For Dharwad and Bagalkot, customers can send photographs of the pump from multiple angles along with the machine identification plate. This can be particularly useful where the original part number is partially damaged or difficult to read.

Information required for pump identification

• HAMM machine model

• Machine serial number

• Machine year, if available

• Existing pump manufacturer

• Complete pump model

• Pump identification number

• HAMM part number

• Displacement

• Rotation direction

• Control configuration

• Shaft specification

• Mounting information

• Number of pumps

• Hydraulic function

• Clear pump nameplate photograph

HAMM Hydraulic Pump Supply for Karnataka Customers

Hydraulic-pump requirements can range from complete replacement units to pump repair, testing and associated hydraulic components. Multitech India focuses on matching the requirement with the actual machine configuration instead of supplying a pump based only on a generic model description.

For Ramanagara and Chikkamagaluru, customers can begin an enquiry by sharing their HAMM machine and existing pump information. This allows the requirement to be checked before deciding whether a replacement or repair route is appropriate.

For Haveri and Madikeri, pump enquiries can similarly be supported using the original hydraulic-component details. Older equipment should always be checked against the available machine and pump documentation.

HAMM Hydraulic Pump Identification Story

A Karnataka road contractor once experienced inconsistent vibration from a HAMM roller during a road-compaction project. The machine could still travel normally, so the operator initially suspected a mechanical problem with the vibration assembly. Instead of immediately replacing components, the machine identification plate and hydraulic-pump nameplate were photographed and the affected hydraulic circuit was traced.

The pump identification showed that the machine required a variable-displacement hydraulic unit with a specific control configuration. A visually similar pump was therefore not treated as a direct replacement. The contractor was able to proceed after the pump specification was checked against the machine configuration. The situation demonstrated why the complete pump code, machine serial number and hydraulic function are important when sourcing a HAMM hydraulic pump.
