Specifications

The 50 Gallon Upright Reservoir/Direct Mount Pump Wetline Kit with a Poly Tank and Counterclockwise (CCW) rotation is an engineered solution designed for the rigorous demands of heavy-duty commercial applications, particularly within the dump body and material handling sectors. This comprehensive kit provides all essential components required to establish a high-performance hydraulic power unit, directly integrating with a vehicle's Power Take-Off (PTO) system to operate various hydraulic functions with efficiency and reliability.

A wetline kit, in the context of mobile hydraulics, refers to a complete system that supplies hydraulic fluid under pressure to operate auxiliary equipment. Unlike "dryline" systems, which typically involve only the mechanical connection for a PTO, a wetline system includes the reservoir, pump, control valves, hoses, and fittings necessary to generate, store, and transmit hydraulic power. This particular kit is meticulously assembled to ensure compatibility, optimal performance, and ease of installation, thereby minimizing downtime and maximizing operational productivity for fleet operators and equipment managers.

The Polyethylene Reservoir: Durability and Performance

At the core of this specific wetline kit is the 50-gallon polyethylene upright reservoir. The selection of polyethylene as the reservoir material is a deliberate engineering choice, offering several distinct advantages over traditional steel or aluminum reservoirs, especially in certain operating environments. Polyethylene, often high-density polyethylene (HDPE) or cross-linked polyethylene, provides exceptional corrosion resistance, rendering it impervious to rust and many chemical contaminants frequently encountered in outdoor and industrial settings. This characteristic significantly extends the lifespan of the reservoir and helps maintain the purity of the hydraulic fluid, which is paramount for the longevity of the entire hydraulic system. Furthermore, polyethylene reservoirs are inherently lighter than their metallic counterparts, contributing to a reduction in overall vehicle weight, which can translate to improved fuel economy and increased payload capacity.

The material's inherent flexibility and impact resistance also make it highly durable, capable of absorbing shocks and vibrations without denting or fracturing, a common issue with rigid metal tanks in demanding applications. The translucency characteristic of some polyethylene formulations can provide a visual indication of the fluid level, facilitating quick pre-operation checks without the need for additional sight gauges, although dedicated fluid level indicators are typically integrated for precision. Polyethylene also exhibits excellent thermal stability within typical hydraulic operating temperature ranges and is compatible with a wide spectrum of hydraulic fluids. The "upright" design configuration of this 50-gallon reservoir is optimized for space efficiency on truck frames, allowing for flexible mounting options while often improving the net positive suction head (NPSH) for the pump, which is crucial for preventing cavitation.

The 50-gallon capacity is carefully selected to ensure an adequate volume of hydraulic fluid for heat dissipation and to meet the operational demands of typical dump applications. Sufficient fluid volume helps to manage heat buildup, thereby preserving the integrity of the hydraulic fluid and extending the life of seals and other components. Integrated into the reservoir design are provisions for proper fluid return, typically with diffusion mechanisms to minimize aeration, and often includes an internal baffle system to prevent sloshing and aid in debris settlement. Breather caps with integrated air filters are standard, preventing the ingress of atmospheric contaminants into the hydraulic system while allowing for pressure equalization during fluid level changes.

The Direct Mount Pump/Valve Assembly: Power and Precision

Central to the kit's functionality is the cast iron pump/valve combination, engineered to deliver a robust flow rate of 46 Gallons Per Minute (GPM) at 1800 RPM. This unit is specifically designed for direct mounting to the PTO, creating a highly efficient and compact power unit. The pump type is typically a heavy-duty gear pump, renowned for its simplicity, robustness, and reliability in challenging industrial and mobile applications. Cast iron construction provides exceptional strength, rigidity, and resistance to wear, making it ideal for high-pressure, high-flow environments. Its superior thermal stability and vibration damping characteristics also contribute to reduced noise and extended operational life.

The flow rate of 46 GPM at 1800 RPM is a critical specification, directly correlating to the speed at which hydraulic cylinders (e.g., dump hoists) will extend and retract. This flow rate is optimized to provide rapid cycle times for dump operations, enhancing productivity without overstressing the system. The 1800 RPM refers to the input speed required by the pump, which is typically matched to the output speed of the vehicle's PTO when engaged. Proper matching of the PTO's gear ratio and the pump's displacement is essential to achieve the rated flow and prevent inefficiencies or damage.

The integration of the valve assembly directly with the pump offers significant advantages. This combination unit streamlines the hydraulic circuit, reducing the number of external hoses and fittings, which in turn minimizes potential leak points and simplifies installation. The valve typically incorporates essential functions such as lift, hold, and lower for the dump body. It often includes an adjustable pressure relief valve to protect the system from overpressure, ensuring safe operation and preventing damage to components. The direct mount configuration eliminates the need for an intermediate driveshaft, reducing complexity, minimizing alignment issues, and creating a more compact and robust power unit that can withstand the vibrations and stresses inherent in mobile equipment operation.

A crucial specification for this particular kit is the "Counterclockwise" (CCW) pump rotation. The direction of pump rotation must precisely match the rotational direction of the PTO output shaft when viewed from the drive end. Incorrect rotation will prevent the pump from priming and can lead to immediate damage to the pump and potentially the PTO. This CCW designation ensures compatibility with a specific range of vehicle PTO configurations, and it is imperative for users to verify their PTO's rotational direction before installation. Contacting customer service for verification, as suggested, is a prudent step to ensure proper system setup.

Hoses and Fittings: The Lifelines of Hydraulic Power

The integrity of a hydraulic system heavily relies on its hoses and fittings, which serve as the conduit for fluid power. This kit includes a comprehensive selection designed for durability and performance:

• 6 ft Internally Reinforced 1-1/4 in. Suction Hose: The suction line is critical for drawing hydraulic fluid from the reservoir to the pump. Its larger diameter (1-1/4 inch) is specifically chosen to minimize flow restriction and pressure drop, preventing cavitation – a destructive phenomenon caused by insufficient fluid supply to the pump. Internal reinforcement ensures the hose maintains its shape under vacuum, preventing collapse and ensuring a steady, unimpeded flow of fluid, even under demanding conditions. The 6-foot length provides flexibility for routing to the upright reservoir.
• (2) 1-1/4 in. Barbed Adapter Fittings and (2) 1-1/4 in. Stainless Steel Hose Clamps: These components facilitate secure and leak-proof connections for the suction hose to the reservoir and the pump inlet. Barbed fittings provide a strong mechanical grip within the hose, while stainless steel clamps offer excellent corrosion resistance and robust clamping force, ensuring a durable seal against pressure and vibration.
• 1 in. High Pressure Swivel Adapter: This adapter is vital for connecting the high-pressure line from the pump/valve assembly to the rest of the hydraulic circuit, such as the quick-detach coupling. Its swivel capability allows for rotational adjustment during installation, preventing hose twist and reducing stress on connections, thereby extending hose life and easing maintenance. It ensures a flexible, secure connection even in dynamic operating environments.
• 1 in. Wing-Type High Pressure Quick Detach Coupling: This component is a cornerstone of operational flexibility. The quick-detach coupling allows for rapid and tool-free connection and disconnection of the high-pressure hydraulic line to a dump trailer or other hydraulically actuated equipment. The "wing-type" design refers to its robust, user-friendly locking mechanism, often featuring large levers for easy manipulation even with gloved hands. Key benefits include:
  • Versatility: Enables a single power unit to operate multiple trailers or attachments.
  • Reduced Downtime: Quick changes minimize time spent connecting and disconnecting.
  • Contamination Control: Designed to minimize fluid spillage and prevent dirt and moisture from entering the hydraulic system during connection and disconnection.
  • Safety: Engineered to withstand high pressures, ensuring a secure connection during operation.
• 1 in. High Pressure Hose, 6 ft long: This hose is constructed to withstand the elevated pressures generated by the pump. Typically comprising multiple layers of synthetic rubber and high-tensile wire braid reinforcement, it offers exceptional strength, flexibility, and resistance to abrasion, oils, and environmental factors. The 6-foot length provides adequate reach for connecting the pump to the quick-detach coupling, allowing for proper routing while avoiding sharp bends that could compromise hose integrity.

Mounting and Isolation: Foundation for Longevity

The stability and longevity of any mobile hydraulic system are greatly influenced by its mounting and vibration isolation. The kit includes:

• Frame Bracket Kit with Fasteners: Designed specifically for the upright reservoir, this kit provides a robust and secure mounting solution to the vehicle's frame. The brackets are engineered to distribute the weight of the full reservoir evenly and withstand dynamic forces encountered during vehicle operation, ensuring the reservoir remains firmly in place. High-grade fasteners are included to guarantee a reliable, long-lasting attachment.
• Reservoir Isolation Package: This critical component set, typically consisting of rubber isolators, pads, or specialized mounts, serves to dampen vibrations and absorb shocks transmitted from the vehicle frame to the reservoir. Vibration isolation is paramount for preventing stress fatigue in both the reservoir and its mounting points, reducing noise, and protecting the hydraulic fluid from aeration caused by excessive agitation. By isolating the reservoir, the overall lifespan of the system components is significantly extended.

Applications, Installation, and Maintenance

This 50 Gallon Upright Reservoir/Direct Mount Pump Wetline Kit is an indispensable component for a wide array of heavy-duty applications requiring dedicated hydraulic power. Its primary application is for dump trucks and trailers, providing the hydraulic force necessary to raise and lower the dump body.

For optimal performance and safety, professional installation is strongly recommended. This involves meticulous attention to hose routing to avoid chafing and kinking, proper tightening of all fittings to prevent leaks, secure mounting of the reservoir and pump, and verification of the correct pump rotation. Prior to initial operation, the hydraulic system must be properly filled with the correct type and viscosity of hydraulic fluid, and thoroughly bled to remove any trapped air, which can cause erratic operation and damage components. Fluid cleanliness is paramount; only filtered fluid should be introduced into the system.

Regular preventative maintenance is crucial for maximizing the lifespan and reliability of the wetline kit. This includes periodic inspection of all hoses and fittings for signs of wear, leaks, or damage; routine checks of the hydraulic fluid level and condition; scheduled filter changes (if applicable, such as a return line filter, which may be integrated into some reservoir designs or plumbed separately); and monitoring for any unusual noises or performance degradation from the pump or valve. Adhering to manufacturer guidelines for fluid specifications and maintenance schedules will ensure sustained high performance and reduce the total cost of ownership.
