HYDM-DF-D-2.36-XWL41 Hydraulic Motor | 2.36 cid Danfoss

HYDM-DF-D-2.36-XWL41 Hydraulic Motor | 2.36 cid Danfoss

• HYDM-DF-D-2.36-XWL41 is a compact, direct-drive hydraulic motor kit
  built around a Danfoss D-Series external-gear motor with
  2.36 in³/rev (≈38.7 cc) displacement.
• Engineered to spin Annovi Reverberi (AR) triplex pumps smoothly
  without belts or a separate engine/electric drive.
• Motor and pump mount on a shared, rigid base that keeps both shafts on the same
  centerline, shrinking the footprint for tight skids, service bodies, enclosed vans,
  and plant carts.
• Precise centerline alignment reduces side-loads on bearings and seal packs so the
  assembly runs cooler, quieter, and longer than belt systems.
• Balanced LSHT gear-motor design delivers confident starting torque and calm,
  predictable speed for small- to mid-frame AR pumps in high-pressure washdown and
  process-rinse duty.
• Alignment-friendly layout preserves clear access to the coupling, oil sight glass,
  vented dipstick, and fasteners so a single technician can perform coupling checks,
  oil changes, and torque verification with common tools.

Mounting & Packaging

• Shared rigid base with slotted patterns keeps the motor-to-pump position
  predictable for repeatable shop and OEM builds.
• Perimeter space is planned for short, direct suction runs and
  tidy pressure and bypass routing.
• Provides room to mount an unloader block without tight bends or guard conflicts,
  simplifying future pump swaps and field service.

Hydraulic Motor & Porting

• Motor type & brand:
  Danfoss D-Series external-gear LSHT, 2.36 in³ (≈38.7 cc).
• Typical hydraulic ports:
  SAE-12 ORB (3/4″) pressure/return and
  SAE-8 ORB (1/2″) case-drain when required (verify selected
  build).
• Observe A/B port orientation for correct rotation and route the case-drain above
  reservoir oil level to prevent aeration.
• Size hose IDs generously and respect minimum bend radii on all lines to avoid
  restriction and excess heat.

Sizing & Power Calculations

• Estimate pump speed with:
  rpm ≈ 231 × hydraulic gpm ÷ motor displacement (cid).
• Estimate shaft torque with:
  lb-in ≈ motor displacement (cid) × psi ÷ 6.283.
• Plan hydraulic horsepower with:
  hp ≈ gpm × psi ÷ 1714, then apply realistic system efficiency to
  confirm available shaft power at your nozzle selection.

Circuit Protection & Cooling

• HYDM-DF-D-2.36-XWL41 Protect the circuit with upstream relief valves set to the working pressure for
  your duty class.
• Specify 10–25 μm return filtration with an adequate β-rating and
  keep the reservoir clean.
• Size the reservoir for heat rejection using
  2–3× total system flow as a practical guideline.
• Add an oil cooler for hot climates, prolonged bypass, or continuous-duty
  applications.

Water-Side Plumbing

• Intended for small- to mid-frame AR pumps:
  typical small-frame ports are
  1/2″ F-BSPP inlet / 3/8″ F-BSPP outlet.
• Typical mid-frame ports are
  1″ F-BSPP inlet / 1/2″ F-BSPP outlet; adapters to NPT
  are readily available.
• HYDM-DF-D-2.36-XWL41 Keep the suction run short, straight, and oversize from a flooded feed; use
  anti-collapse suction hose and a coarse inlet strainer to preserve volumetric
  efficiency and prevent cavitation.
• Size the unloader and high-pressure relief to the chosen AR duty class and add
  a glycerin-filled gauge for commissioning and diagnostics.
• Include a thermal relief valve on the bypass loop to protect seals during
  extended gun-closed operation.
• DI/chemical-friendly plumbing possible when seals, hoses, and fittings are
  specified for media compatibility.

Pump Manufacturer & Warranty

• Pump manufacturer:
