Hansa-TMP

Hansa-TMP is an Italian manufacturer of hydraulic drive components that has been supplying specialized hydraulic motors and pumps for the mobile and industrial market for many years. The company, founded in Italy, has built a solid reputation as a supplier of reliable radial hydraulic motors, gear pumps, and hydraulic tandem combinations to leading OEM machine builders in Europe and worldwide.

The core product of Hansa-TMP are the radial hydraulic motors used for driving travel movements, winches, drilling machines, and hoisting installations in construction machinery, agricultural machines, and industrial equipment. The radial motor construction is characterized by high torque density at low speed, compact dimensions, and robust design for heavy-cycle operation. The motors are available in a wide displacement volume range, enabling torque and speed to be matched to the specific drive task.

In addition to radial motors, Hansa-TMP supplies gear motors and gear pumps for medium and high-pressure hydraulic circuits. The gear pumps are used as hydraulic supply pumps in mobile machinery and industrial hydraulic systems, and are available as single pumps and as tandem combinations where two pumps are mounted on one drive shaft for simultaneous supply of multiple hydraulic circuits. The gear pumps are distinguished by high volumetric efficiency, low pulsation, and long service life in continuous operation.

For installing and coupling Hansa-TMP motors and pumps, the company supplies a wide range of mounting flanges in SAE and ISO configuration, drive couplings, hydraulic manifolds for combining multiple connections, and measurement ports for pressure and flow measurement in the hydraulic circuit. Seal kits are available for overhaul of all common Hansa-TMP motor and pump types, including shaft rotary seals, O-rings, and valve seats.

Verkopershulp.nl supplies Hansa-TMP hydraulic motors, gear pumps, and associated parts for replacement and overhaul of hydraulic drives. Our hydraulic systems team advises on choosing the correct displacement volume, pressure class, mounting flange, and shaft configuration for your specific hydraulic application.

History

Hansa-TMP was founded in Italy as a specialized manufacturer of hydraulic motors and pumps for the European market. The company focuses specifically on developing and producing radial motors and gear hydraulics for demanding mobile and industrial applications. Through a consistent focus on quality and the supply of wide configuration variants of its product range, Hansa-TMP acquired a firm position as a supplier to European machine builders in the construction and agricultural sector, alongside deliveries to hydraulic system integrators and the aftermarket for hydraulic drive components.

Frequently Asked Questions

How do I select the correct displacement volume for a Hansa-TMP radial motor?
Displacement volume determines the torque the motor delivers at a given hydraulic pressure. Torque (Nm) equals displacement volume (cm³/rev) multiplied by differential pressure (bar) multiplied by the mechanical efficiency factor, divided by 20π. A higher displacement volume gives more torque at lower speed. Choose a lower displacement volume for higher speed with less torque requirement. Provide us your required torque and speed and we calculate the optimal displacement volume for your Hansa-TMP motor.
Are Hansa-TMP gear pumps suitable for continuous high pressure?
Hansa-TMP gear pumps are designed for continuous working pressures up to 250 bar and peak pressures up to 280 bar, depending on the model. For continuous high-pressure operation above 200 bar, versions with reinforced bearing housing and hardened gears are available. The pumps are not suitable for closed hydraulic circuits; use axial piston pumps or plunger pumps for closed circuits.
Which shaft configurations are available for Hansa-TMP motors?
Hansa-TMP radial motors are standard available with cylindrical output shaft conforming to DIN 748, splined shaft conforming to DIN 5480 (metric), and SAE splined shaft for coupling with American SAE standard drive elements. Special shaft versions with clamping coupling, flange shaft, or hollow shaft are available on request. Specify when ordering the desired shaft type and desired mounting flange for the correct motor version.
How do I replace the shaft seal of a Hansa-TMP gear pump?
Dismount the pump from the hydraulic installation and clean the exterior. Remove the shaft seal plate by loosening the retaining bolts. Carefully extract the existing shaft rotary seal (lip seal) from the seal plate using an internal puller. Inspect the drive shaft for wear or damage. Press the new rotary seal evenly into the seal plate with a suitable drift until it seats. Apply a thin coat of hydraulic oil to the seal lip. Refit the seal plate with a new O-ring and tighten the retaining bolts to the specified torque.
Can I use a Hansa-TMP motor as a hydraulic pump?
Technically, certain Hansa-TMP gear motors can also be used as pumps at low pressures, but this is not recommended. Hydraulic motors are optimized for motor operation (high input torque, high pressure) and not for pump operation (high flow at low input pressure). Use as a pump leads to lower volumetric efficiency and faster wear. Use the specific Hansa-TMP gear pump models for pump applications.
Are Hansa-TMP radial motors suitable for low-speed high-torque applications?
Yes, Hansa-TMP radial hydraulic motors are eminently suitable for low-speed high-torque (LSHT) applications. Radial motors deliver high torque from standstill, making them ideal for direct driving of winches, travel rollers, and boring tools without the need for a gearbox. Speeds from 0 to approximately 400-800 rpm are common, depending on the displacement volume.
Does Verkopershulp.nl supply seal kits for Hansa-TMP motors?
Yes, Verkopershulp.nl supplies original Hansa-TMP seal kits for all common motor and pump types. The kits contain all necessary rotary seals, O-rings, and gaskets for a complete overhaul of the hydraulic motor or pump block. Provide the complete type and serial number of your motor or pump for the exact kit composition.
What is the intended service life of a Hansa-TMP radial hydraulic motor?
Hansa-TMP radial motors are designed for a service life of more than 10,000 operating hours with correct maintenance, clean hydraulic oil (ISO VG 46 or ISO VG 68, contamination class maximum ISO 18/16/13), and operation within the permitted pressure and temperature limits. Regular replacement of hydraulic oil and filters is the most important maintenance measure for maximum service life.
