HYD-RTX-SP Hydraulic Pump Solar Panel Cleaning

HYD-RTX-SP Hydraulic Pump Package | Solar Panel Cleaning

• HYD-RTX-SP is a purpose-built, belt-free solar-cleaning package that directly couples a low-speed/high-torque (LSHT) hydraulic motor to an Annovi Reverberi RTX-series triplex plunger pump on a rigid, alignment-stable base.
• Delivers smooth, controllable rinse flow to brushes and rinse bars in a compact footprint that fits rooftop carts, lift baskets, vans, trailers, and plant carts.
• Manufactured by Annovi Reverberi in Modena, Italy—recognized since 1958 as a leader in high-pressure pump quality.
• Pump ships with factory oil, an easy-view sight glass, and a vented dipstick so a single technician can complete pre-start checks and routine PM quickly.
• Coaxial motor and pump on a shared mounting plane keep shaft centerlines true, minimizing side loading on bearings and seal packs for longer life and quieter operation than belt drives.

Hydraulic Circuit & Motor

• Uses a displacement-matched LSHT gerotor/geroler-type hydraulic motor (brand may vary) sized to reach the desired low-pressure rinse speed.
• Interfaces with standard hydraulic circuits via pressure and return ports typically SAE-12 (3/4″ ORB), plus a case-drain port commonly SAE-8 (1/2″ ORB) when required by the motor build.
• HYD-RTX-SP Observe A/B port orientation for correct rotation and route the case drain above tank oil level to prevent aeration.
• Protect the circuit with upstream relief valves sized for the system, and specify 10–25 μm return filtration with an adequate β-rating.
• Size the hydraulic reservoir for heat rejection and add an oil cooler for hot climates, extended brush duty, or continuous operation.

HYD-RTX-SP Water-Side & DI Plumbing

• RTX manifolds are straightforward to plumb—typical ports are a 1″ F BSPP inlet and a 1/2″ F BSPP discharge; some larger RTX variants provide a 1-1/4″ inlet. Adapters to NPT are readily available.
• Keep suction plumbing short, straight, and oversize from the DI tank; include a coarse inlet strainer and use anti-collapse suction hose to protect volumetric efficiency and prevent cavitation.
• Because solar work prioritizes glass and coating safety, the package is configured for low pressure and steady flow rather than aggressive cutting pressure.

Solar Cleaning Duty & Setpoints

• Select the specific RTX model and nozzle/brush orifice to hit target rinse performance.
• Typical solar setpoints are 3–8 GPM per brush at 150–400 PSI.
• System can be configured across a broader range of roughly 2–12 GPM and 100–600 PSI depending on array size, brush type, and pump selection.
• Use an adjustable unloader to fine-tune impact on the panel face and add a high-pressure relief and glycerin-filled gauge for commissioning and diagnostics.
• Incorporate DI-water best practices: inline filtration (sediment + carbon as needed), a TDS monitor to verify low total dissolved solids for spot-free drying, and a low-pressure recirculation path for prolonged bypass so water stays cool.

HYD-RTX-SP Integration & Layout Notes

• Plumbing layout is “field-tech friendly,” with short suction, tidy pressure and bypass routing, and perimeter space for an unloader block without tight bends.
• Predictable hose runs support repeatable OEM builds and keep coupling and fastener access open for torque checks.
• Compact belt-free geometry calms trigger cycling, reduces hose whip, and simplifies routing around tanks, filters, reels, and guides.

Ownership, Warranty & Support

• RTX pumps feature ceramic plungers, oversized bearings, and proven valve geometry for long life on intermittent or continuous rinse duty when operated within published limits.
• Follow Annovi Reverberi’s lubricant recommendations and service intervals; confirm seal and O-ring compatibility with DI water and any approved detergents, and observe temperature limits for seals.
• HYD-RTX-SP Pump is covered by a 5-year limited, conditional warranty from Annovi Reverberi.
• Warranty coverage requires proper installation (hydraulic and water), correct filtration and lubrication, and operation within specification; seals and valves are treated as consumable wear items.
