HYD-RTDSS80.300HN-DD Hydraulic Pump | SS Head 21 GPM 4350 PSI

HYD-RTDSS80.300HN-DD Hydraulic Pump | SS Head 21 GPM 4350 PSI

• HYD-RTDSS80.300HN-DD is a ready-to-integrate hydraulic drive package coupling a low-speed/high-torque (LSHT) hydraulic motor directly to an Annovi Reverberi RTDSS80.300 triplex plunger pump.
• Rated for 21 GPM (80 L/min) at 4350 PSI (300 bar) at 1000 RPM without belts, pulleys, or re-tensioning.
• Manufactured in Modena, Italy by Annovi Reverberi, global leader in high-pressure pump engineering since 1958.
• 420 stainless steel pump head provides elevated corrosion resistance for hot, wet, and chemically aggressive environments.
• Rigid, alignment-stable base maintains true shaft centerlines to minimize bearing and seal side-load.
• Compact footprint and reduced vibration support crowded bays and mobile skid installations.

Hydraulic Motor & Drive System

• LSHT hydraulic motor (gerotor/geroler type) commonly used across mobile and industrial equipment.
• Motor displacement is matched to achieve 1000 RPM pump speed at rated duty.
• Direct-coupled configuration eliminates belt dust, pulley wear, and alignment drift.

Hydraulic Ports & Circuit Requirements

• Pressure / return ports: typically SAE-12 (3/4″) O-ring boss.
• Case drain: SAE-8 (1/2″) when required by motor build.
• Follow motor rotation arrows and A/B port orientation.
• Route case drain above reservoir oil level to prevent aeration.
• Protect the circuit with upstream relief valves rated for 300 bar service.

Water-Side Plumbing Interface

• HYD-RTDSS80.300HN-DD RTD stainless head configured for high-flow industrial plumbing.

Water Ports

• Inlet: 1-1/2″ F BSPP.
• Discharge: 1″ F BSPP (adaptable to NPT).

Water-Side Installation Practices

• Keep suction run short, straight, and generously sized.
• Use coarse inlet strainer and anti-collapse suction hose.
• Install adjustable unloader sized for 300 bar duty.
• Add high-pressure relief and glycerin-filled pressure gauge.
• Ceramic plungers, bronze rods, and oversized bearings support continuous-duty operation.

Integration & System Sizing

• Verify hydraulic flow is sufficient to maintain 1000 RPM under load.
• Set system relief valves correctly and confirm valve stack capacity.

Cooling & Filtration

• Specify 10–25 μm return filtration with adequate β-rating.
• Size reservoir at 2–3× pump flow for heat rejection.
• Add oil cooler for continuous bypass or hot-climate duty.

HYD-RTDSS80.300HN-DD Operating Safeguards

• Install thermal relief on bypass loop to protect seals during gun-closed operation.
• Observe hose bend radii and avoid restrictive fittings.
• Confirm seal compatibility with detergents, chemicals, and operating temperatures.
• Select nozzle sizes for rated flow and pressure and never overspeed the pump.

Applications

• Marine & aquaculture: tug boats, work boats, dock sanitation, fish pens.
• Food & beverage: sanitation lines, packaging rooms, CIP support (local standards apply).
• Municipal & sanitation: sewer jetting support skids, vacuum trucks, street equipment.
• Agriculture & ranch: equipment wash, fertilizer cleanup, mobile spray systems.
• Industrial plants: conveyor cleaning, parts washing, paint prep.
• Rental & heavy equipment: contractor skids and fleet washdown systems.

Service & Ownership HYD-RTDSS80.300HN-DD

• Ships with factory oil fill, sight glass, and vented dipstick.
• Maintenance intervals follow Annovi Reverberi published schedules.

Preventive Maintenance

• Pump oil changes at specified intervals.
• Inlet filtration inspection and replacement.
• Periodic torque checks on head, manifold, base, and coupling fasteners.
