Rickmeier gear pump

1、 Product Overview

• application fieldHydraulic systems, lubrication systems, and oil transportation cover 19 industries including engineering machinery, automotive manufacturing, wind power, ships, and chemical equipment.

• Typical mediaHydraulic oil, gear oil, diesel, engine oil, cutting oil, etc. (medium gas content ≤ 10%).

• 
  

• Core Features：

• Short straight channel design, low-noise gear structure, excellent oil absorption performance.

• Shell material: Grey cast iron EN-GJL-250 (optional ductile iron EN-GJS-400-15).

• Transmission components: carburizing hardened steel gear shaft; Composite sliding bearings (including lead-free options).

• Shaft seal standard configurationRadial shaft seal ring (RWDR), optional slip ring seal (GLRD) or magnetic coupling (MK) to achieve zero leakage.

2、 Key technical parameters

1. Usage restrictions(Standard specifications):

   parameter	minimum	maximum
   Kinematic viscosity	5 mm²/s	20,000 mm²/s
   Pollution level (ISO 4406)	-	21/19/17
   Temperature (NBR seal)	-25°C	80°C
   Temperature (FKM seal)	-25°C	150°C
   Inlet pressure (during RWDR operation)	-0.4 bar	0.5 bar
   Inlet pressure (MK seal)	-0.4 bar	16 bar

2. Maximum operating parameters(Partial examples):

   structural dimensions	Displacement (cm ³)	Maximum pressure (bar)	Maximum speed (rpm)	Sound pressure level [dB (A)]
   R25	20	25	3600	59
   R95	1800	25	1800	87
   R105	2600	12	1600	90

3. Flow and power(Mineral oil, viscosity 33 mm ²/s):

• The flow rate decreases with increasing pressure (for example, the flow rate of R25/10 cm ³ pump drops to 0.9 L/min @ 950 rpm at 25 bar).

• The driving power demand increases with pressure/viscosity (a 10% motor power margin should be reserved when selecting).

3、 Configuration Options

1. modular design：

• interface typeBritish thread, SAE flange (standard), DIN flange (R95/R105), customized axial/misalignment interface.

• Shaft end formCylindrical with sliding key (standard), conical seat, spline shaft, Oldham coupling.

• Pressure limiting valve (DB)Integrated spring valve (pressure range 1-25 bar), with optional damping/heat resistance/pilot control specifications.

• rotation directionRight rotation (R), left rotation (L), bidirectional rotation (C/UNI).

2. special specifications：

• noise optimizationFor gas containing media, the maximum reduction in sound pressure level is 15 dB (A).

• double pumpSuitable for R25/R35/R45 sizes.

• corrosion protectionTwo component paint (optional C4 coating).

4、 Size and weight

5、 Pump unit and accessories

• Motor compatibilityStandard configuration includes IE3 three-phase asynchronous motor and supports customization of DC motor.

• Installation type：

• IM B35Flange installation (see pages 37-47 of the manual for size chart).

• IM B5Equipped with a pump bracket base (heavy-duty structure recommended for high vibration scenarios).

• Key attachments：

• Coupling (elastic/toothed, suitable for different motor shaft diameters).

• SAE/DIN connection flange (including welding/thread specifications).

• Pump bracket (such as R95 bracket weighing 4.15-19.0 kg).
