Optimized, in so many ways.

Danfoss’ fixed displacement motors are designed for use in mobile equipment using existing and proven technology. These motors have been optimized around product life, package size, option variety, and low installation effort.


Danfoss fixed displacement piston motors offer a wide range of capacities, with displacements ranging from 12 cm3 to 125 cm3 [0.75 in3 to 7.6 in3] and continuous pressure ranges from 210 bar to 480 bar [3,000 psi to 7,000 psi].

New! H1F Fixed Motors

The next chapter of the H1 legacy is here! Our new H1F fixed displacement bent-axis hydraulic motor is designed for open- and closed-circuit applications, and offers a compact design, proven reliability, and efficiency – up to 95% - completely surpassing the competition, no matter the pressure rating or rotational speed. The lightweight H1F motor features a power-dense, compact envelope for ease of installation. With its short length and 32-degree angle, the package size is one of the most compact on the market, enabling machine manufacturers to reduce the space claim of the hydraulic system.

Key benefits:

  • Proven H1 technology, building on the solid legacy of H1B bent-axis motors
  • Up to 95% efficiency – leading to fuel savings, improved productivity, and reduced heat
    generation
  • System pressure up to 510bar (abs), 480bar (delta)
  • Can be used for open- and closed-circuit applications
  • Our 80cc is the first frame size – many more to come, from 60cc to 250cc

MP1 fixed displacement axial piston motors

MP1 motor is our next generation of fixed displacement axial piston motors. The MP1 motor is designed for use in mobile equipment using existing and proven technology.

These motors have been optimized around product life, package size, option variety, and low installation cost.

We offer rapid prototype delivery which will allow your application to get faster into the market.

MP1 motors are offered in four displacements in two package sizes, 20/24 and 28/32cc/rev, and are capable of operating in closed-loop and open-loop systems. Different mounting configurations are available: SAE A, B, and cartridge style two-bolt flange.

New! Now available - twin axial port and split flange for MP1M 28/32, in addition to the original twin radial port.

Fan Drive Systems

MP1 motors can be used in different fan drive circuits along with other Danfoss products, offering great versatility and flexibility to fit your needs.

Examples of Fan Drive system solutions using MP1 motors:

Features and benefits

Easy installation: Lightweight aluminum housing, shortest length in the market, low volume occupation in tight spaces such as engine compartments

Easy integration: Compact package size, cartridge mounting for easy integration into fan shroud, system solution when combined with other Danfoss products (MP1P, DDC20, S45, PLUS+1)

High efficiency: Lower fuel cost, more productivity, allows for downsizing with equal or better machine performance

High pressure capability: Max working pressure of 350 bar, enables downsizing of the Fan Drive system, higher durability and longer life

Wide range of options: PLUS+1 Compliant speed sensor, integrated loop flushing valve option, anti-cavitation and shock valve option, two displacements in a single package, SAE A, B, and cartridge style two-bolt mounting configurations available, tapered shaft with optional shaft seal dust protector for fan drive applications
