AR26472 RK15.20 Hydraulic Pump | NPT Ports RK Series

Overview

The AR AR26472 RK15.20 NPT Hydraulic Pump is a premium-grade, hydraulically driven
pressure pump from Annovi Reverberi’s renowned RK Series, engineered for exceptional flow efficiency,
durability, and precision in demanding industrial and commercial cleaning systems. Designed specifically
for integration into hydraulic-powered setups, the RK15.20 delivers smooth torque transmission,
reliable pressure stability, and long-term performance in continuous-duty applications.

NPT (National Pipe Thread) suction and discharge ports provide secure, standardized connections for easy
plumbing into U.S. hydraulic and water systems. With its forged brass head, ceramic plungers, and
heavy-duty crankcase, this pump offers the strength, efficiency, and reliability required for mobile
rigs, fleet wash stations, and industrial washdown equipment where uptime is critical.

Key Features & Applications

Forged Brass Manifold & Industrial Build

• Forged brass manifold head resists pitting, cracking, and fatigue under high pressure and temperature.
• Corrosion-resistant construction stands up to water, detergents, and harsh cleaning chemicals.
• Dimensional accuracy maintains tight sealing surfaces for long-term leak-free performance.
• Ideal for heavy-duty environments including mobile hydraulic wash systems and fixed industrial stations.

Ceramic Plungers & Heavy-Duty Crankshaft

• Precision-ground ceramic plungers provide superior wear resistance and excellent heat dissipation.
• Hardened, forged crankshaft runs on tapered roller bearings for smooth, low-friction operation.
• Balanced internal geometry minimizes vibration and noise for quiet, stable performance.
• Robust drivetrain design extends the life of both the pump and the driving hydraulic motor.

Hydraulic Direct-Drive with NPT Connections

• Designed to couple directly to hydraulic motors—no belts, pulleys, or extra drive components required.
• Direct-drive layout improves torque transfer efficiency and reduces mechanical wear.
• NPT inlet and outlet ports ensure leak-free, U.S.-standard plumbing with common fittings and hoses.
• Maintains consistent flow and pressure output even under variable hydraulic load conditions.

Optimized Flow Path, Cooling & Sealing System

• Precisely machined internal passages promote smooth fluid flow and reduce cavitation risk.
• Die-cast aluminum crankcase with cooling fins enhances heat dissipation for extended duty cycles.
• Sealed crankcase with sight glass, vented fill cap, and drain plug simplifies oil checks and changes.
• High- and low-pressure synthetic seals and stainless-steel valves maintain pressure integrity and volumetric efficiency.

Installation Flexibility & Typical Uses

• Compact footprint fits easily on trailers, vehicles, skids, and industrial frames.
• NPT fittings and hydraulic drive allow straightforward integration into new or existing systems.
• Well-suited for fleet and equipment washing, agricultural and construction washdown, and industrial cleaning lines.
• Stable, high-pressure water delivery supports both precision work and large-scale cleaning operations.

Quality Assurance & Service

• Each AR26472 pump is factory-tested for pressure accuracy, flow stability, and leak prevention.
• Engineered for low-maintenance operation—routine oil checks, valve inspections, and periodic seal replacement.
• Corrosion-resistant materials and advanced sealing technology support long service life with minimal downtime.
• Backed by Annovi Reverberi’s reputation for innovation, reliability, and professional-grade pump engineering.
