RK1515-HYD 4.0 GPM 2000 PSI Hydraulic Pump | F38 Flange Mount

RK1515-HYD 4.0 GPM 2000 PSI Hydraulic Pump | F38 Flange Mount

4.0 GPM, 2,000 PSI hydraulic-drive triplex pump

• The AR RK1515-HYD is a high-performance hydraulic-drive pressure pump engineered
  for consistent flow, stable pressure, and long-term durability in demanding service.
• Rated at 4.0 GPM and 2,000 PSI, it provides controlled cleaning strength for
  medium- to heavy-duty industrial, agricultural, and mobile wash systems.
• Ideal for equipment washdowns, spray bars, mobile wash trailers, sanitation rigs, and utility or
  municipal fleet cleaning where hydraulic power is the preferred drive source.

Hydraulic Drive & Mounting

Direct F38 hydraulic flange RK1515-HYD interface

• RK1515-HYD Equipped with an F38 hydraulic flange that mounts directly to compatible
  hydraulic motors for a secure, properly aligned connection.
• Direct-flange configuration eliminates external couplings and extra brackets,
  reducing installation time and potential misalignment issues.
• Ensures accurate shaft alignment, smooth torque transfer, and vibration control, supporting long
  pump life and stable operation.
• Designed to drop into mobile or stationary hydraulic circuits, removing the need
  for separate gas or electric drive motors.

Pump Architecture

Triplex plunger design for smooth flow

• Built on AR North America’s proven triplex plunger technology for smooth,
  pulse-reduced output.
• Three synchronized pistons balance internal motion and reduce pressure spikes that can damage
  hoses, guns, valves, and nozzles.
• Delivers consistent, predictable pressure across varying load conditions,
  improving cleaning quality and operator control.

Materials & Construction

Corrosion-resistant manifold and ceramic plungers

• Precision-machined brass manifold offers excellent corrosion resistance and
  long-term dimensional stability under continuous high-pressure cycling.
• Internal flow passages are engineered to minimize turbulence and maintain
  hydraulic efficiency.
• Hardened stainless-steel pistons run inside polished solid-ceramic plungers for
  a low-friction pumping stroke and outstanding wear resistance.
• Ceramic plungers resist abrasion, chemical attack, and thermal cycling, helping extend seal life
  and maintain steady pressure output over thousands of hours.
• High-grade elastomer seals and O-rings are formulated to handle repeated
  pressure cycles, chemicals, and temperature swings while minimizing leak risk.

Crankcase & Lubrication

Die-cast aluminum body with splash lubrication

• Die-cast aluminum crankcase provides a strong but lightweight housing with
  excellent heat dissipation for sustained-duty operation.
• Precision-ground crankshaft is supported by oversized bearings to ensure smooth,
  quiet rotation and reduced mechanical vibration.
• Splash-lubricated crankcase continually distributes oil across moving parts to
  reduce friction and extend mechanical life.
• Integrated oil sight glass makes routine level checks quick and simple, helping
  technicians stay ahead of maintenance.

Performance & Energy Transfer

Optimized for hydraulic-driven systems

• Engineered specifically for hydraulic input power, providing efficient energy
  transfer from motor to pump for reliable performance in variable-load environments.
• Operates effectively with both cold and compatible hot water feeds within AR’s
  rated limits.
• Stable pressure output and smooth flow help protect downstream components and
  reduce operator fatigue during long shifts.

Reliability, integration, and low ownership cost

• Easy integration into existing hydraulic circuits simplifies skid, trailer,
  tractor, or truck-mounted system design.
• Minimal maintenance: periodic oil changes plus seal and plunger inspections are
  typically all that’s required.
• Rugged materials and balanced mechanical design help reduce downtime and life-cycle
  cost for fleet and facility operators.
• Every unit is factory tested and calibrated for flow, pressure, sealing
  integrity, and smooth hydraulic response before shipment.

RK1515-HYD Typical Applications

Industrial, agricultural, and mobile hydraulic systems

• Mobile wash trucks and service trailers: on-site equipment cleaning, fleet
  washing, and municipal maintenance.
• Agricultural equipment and sprayers: tractor-driven wash systems, barn and
  implement cleaning, and spray-bar support.
• Construction, forestry, and landscaping machinery: removing mud, clay, and
  debris from heavy equipment in the field.
• Industrial wash platforms and fixed bays: hydraulic-powered cleaning stations in
  plants, warehouses, and sanitation facilities.
• Municipal and utility fleets: pressure cleaning of trucks, vacuum units, sewer
  jetters, and off-road service equipment.

Why Choose the RK1515-HYD

Hydraulic-drive pump built for continuous duty

• Combines a direct-mount F38 hydraulic flange, corrosion-resistant brass
  manifold, and solid-ceramic plungers in a compact, service-friendly package.
• Delivers the 4.0 GPM, 2,000 PSI duty point many mobile and industrial hydraulic
  systems require for everyday cleaning and rinsing tasks.
• Trusted by OEMs and system builders for its quiet, efficient operation and
  proven reliability in continuous-duty environments.
• An excellent choice for mobile wash units, tractor- or truck-driven equipment, and fixed
  hydraulic cleaning bays that demand long-lasting, hydraulically powered performance.
