CMP Series Hydraulic Motors - Frequently Asked Questions

What are the main features and specifications of CMP hydraulic motors?

CMP hydraulic motors are spool valve Gerotor motors for medium to light-duty applications with the following features:

  • Displacement: 49.5 cm³/rev to 396 cm³/rev
  • Max. speed: up to 1100 rpm (CMP 100)
  • Min. speed: down to 5 rpm (depending on model)
  • Max. torque: 12.6 daNm (continuous) up to 52.0 daNm (peak load)
  • Max. output power: 40.0 kW
  • Temperature range: -40 to 140 °C
  • Optimal viscosity: 20–75 mm²/s
  • Recommended filtration: ISO 20/16 (min. 25 µm)

In which typical applications are CMP hydraulic motors used?

CMP hydraulic motors are versatile and are used in, among others:

  • Conveyor systems
  • Feed mechanisms for robots and manipulators
  • Metalworking machines
  • Textile machinery
  • Agricultural machinery
  • Food processing industry
  • Lawn mowers

What types of shaft options are available for CMP motors and what are their torque limits?

  • C-shaft (Ø25 mm straight): Key A8x7x32 DIN 6885 – max. 34 daNm
  • CO-shaft (Ø1" straight): Key ¼"x¼"x1¼" BS46 – max. 34 daNm
  • SH-shaft (splined, SAE 6B): BS 2059 – max. 40 daNm

These variants allow adaptation to different mechanical requirements.

What fluid requirements and recommendations apply for operation?

  • Mineral oil-based Type HM (ISO 6743/4) or HLP (DIN 51524)
  • Optimal viscosity: 20–75 mm²/s
  • Minimum viscosity: 13 mm²/s at 50 °C
  • Max. operating temperature: 82 °C
  • Filtration: ISO 20/16 (min. 25 µm)
  • For synthetic fluids: consult manufacturer for alternative seal options

What is meant by "Continuous operation", "Intermittent operation" and "Peak load"?

  • Continuous: Operation without interruption
  • Intermittent: Max. 10% per minute, speed and pressure drop not simultaneous
  • Peak load: Max. 1% per minute, short-term maximum values

These specifications are important for correct sizing and long service life of the motor.

What are the typical connection types and dimensions?

  • Flange mounting with side ports
  • Main ports: G 1/2 (depth 16 mm)
  • Case drain port: G 1/4 (depth 12 mm)
  • Pilot diameter: Ø82.5 mm
  • Length Lmax: 135.5 mm (CMP 50) to 182.0 mm (CMP 400)

How is the permissible radial shaft load calculated?

The permissible radial load depends on speed (n, RPM) and distance L. Formula:

Prad = 800 / (n / 15000 + (L / 95)) × x (x from diagram values)

Limits:

  • Max. 150 daN (continuous)
  • Max. 200 daN (intermittent)

The limits from the diagrams must not be exceeded to avoid shaft and seal damage.
