M S Hydraulic Motors - Hydromot Hydraulic Shop

M+S hydraulic motors are high-quality components that convert hydraulic energy into mechanical energy. They are designed for demanding industrial applications and offer high quality, reliability, and durability.

Typical applications:

• Agricultural machinery such as salt and fertilizer spreaders
• Construction machinery and mini excavators
• Metalworking machines
• Conveyor belts
• Lawn mowers

They are suitable for both mobile and stationary applications.

M+S Hydraulic offers a wide range of gerotor motors:

• Type MM: Displacement 8.2–50 cm³/rev
• Type MTM: 200–725 cm³/rev
• Type MH: 201.3–502.4 cm³/rev, up to 445 rpm, up to 104 daNm
• Type CMP: 49.5–396 cm³/rev, up to 1100 rpm, up to 40 daNm
• Type MH: 201.3–502.4 cm³/rev, up to 445 rpm, up to 104 daNm
• Type MS: 80.5–564.9 cm³/rev, up to 1125 rpm, up to 99 daNm
• Type MR: 51.5–397 cm³/rev, up to 970 rpm, up to 69 daNm
• Type MT: 161.1–724.3 cm³/rev, up to 775 rpm, up to 148 daNm
• Type MV: 314.5–801.8 cm³/rev, up to 630 rpm, up to 211 daNm

Overall range: torque approx. 45–2110 Nm (peak values for the largest motors).

• Shaft designs: Cylindrical, tapered, splined
• Ports: Side, rear, metric or BSPP
• Seal types: Standard or high pressure
• Special options: Speed sensor, low leakage (LL), free-running (FR), low-speed valves (LSV), tachometer connection, reverse rotation, various coatings including corrosion protection
• Integrated valves: e.g. relief valves in MMP/MMD
• Bearing types: Optional needle bearings (e.g. MR series)

M+S hydraulic motors are manufactured with robust and durable materials:

• Hardened steel for gears and rotor
• Heat-resistant alloys for heavily loaded parts
• High-quality seals

Precision manufacturing ensures tight tolerances, high efficiency, and long service life.

• Regular oil level checks
• Filter replacement according to ISO code 20/16 (min. 25 µm)
• Inspection and, if necessary, replacement of seals & hoses
• Temperature monitoring (optimum 20–75 mm²/s, max. 82°C)
• Before commissioning: fill with fluid and run for 10–15 minutes under moderate load and speed.

• Hydraulic fluid: Mineral oil HLP (DIN 51524) or HM (ISO 6743/4)
• Oil temperature range: -40°C to 140°C
• Optimum viscosity: 20–75 mm²/s
• Max. operating temperature: 82°C
• Filtration: ISO code 20/16, 25 µm or finer
• Intermittent operation: The specified intermittent values for speed and pressure drop must not be reached simultaneously.

• Cylindrical shafts: Ø25–50 mm with keyway, for general applications
• Tapered shafts: 1:10 with keyway, self-centering, for precise alignment
• Splined shafts: ANSI B92.1-1976 or DIN 5482, for high torque and backlash-free connection

When selecting the shaft, the permissible torque output of the shaft type must be observed, as it must not be exceeded. The permissible radial shaft load also depends on the speed and the distance of the load point from the mounting flange.
