XTA3G16EBAF8M2I 3 GPM 1600 PSI | 1750 RPM

XTA3G16EBAF8M2I by Annovi Reverberi — Triplex Plunger Pump with Gymatic Unloader and Chemical Injector | 3.0 GPM | 1,600 PSI | 1,750 RPM | Brass Head | NEMA 56C Electric Motor Mount

The XTA3G16EBAF8M2I by Annovi Reverberi is a commercial-grade triplex ceramic plunger pump engineered for continuous-duty electric motor-driven pressure washing and washdown systems that demand lower operating speed, reduced heat generation, longer seal life, and quieter operation than standard 3,400 RPM pump platforms. Rated at 3.0 GPM and 1,600 PSI at 1,750 RPM, the XTA3G16EBAF8M2I runs at half the crankshaft speed of conventional electric-drive triplex pumps — a fundamental design distinction that makes this pump the correct specification for continuous-duty industrial washdown stations, food and beverage facility sanitation systems, fleet wash bays, and any application where uptime, thermal performance, and long service intervals are the primary operating requirements.

Built by Annovi Reverberi in Modena, Italy — with US-based operations, a domestic parts distribution network, and dedicated AR North America technical support — the XTA3G16EBAF8M2I arrives as a complete, factory-tested assembly. Pre-filled with AR break-in oil, equipped with a Gymatic 3/B unloader and integrated downstream chemical injector, and packaged with mounting bolts and fasteners, a vented dipstick, operator’s manual, and full parts schematic, this pump is ready to install from the moment it arrives. Protected by a 5-year US limited warranty through AR North America and built to be fully rebuilt rather than replaced, the XTA3G16EBAF8M2I is a long-term investment in a pump platform capable of a decade or more of productive continuous-duty service.

Decoding the XTA3G16EBAF8M2I Model Number

What Every Segment of This AR Pump Designation Tells You

Annovi Reverberi encodes all critical specification data — pump series, performance output, shaft type, head material, connecting rod material, flange interface, unloader family, and injector configuration — directly into the model number. Reading the XTA3G16EBAF8M2I correctly before specifying or installing this pump confirms its unique low-speed operating envelope and full factory configuration:

• XTA — Pump series: XA Series triplex plunger pump — AR’s low-speed electric-drive platform, engineered specifically for 1,750 RPM continuous-duty operation with forged brass manifold construction
• 3G16 — Performance rating: 3.0 GPM flow rate at 1,600 PSI maximum operating pressure
• E — Shaft version: Electric motor shaft — compatible with 5/8″ or 1-1/8″ hollow shaft electric motor drives
• BA — Material specification: Forged Brass manifold head with Aluminum connecting rods — brass delivers corrosion resistance and pressure integrity at the wetted end; aluminum connecting rods reduce reciprocating mass for smooth low-speed crankcase operation
• F8 — Flange type: NEMA 56C close-coupling face mount for XTA Series ‘E’ version pumps with 5/8″ I.D. shaft (AR part AR1584)
• M2 — Unloader code: Gymatic (C2 = Gymatic per AR suffix designation) — Gymatic 3/B series internal bypass unloader, brass body, adjustable pressure regulation, factory-fitted
• I — Chemical injector: Included — a downstream soap and chemical injector is integrated into the Gymatic unloader assembly, enabling low-pressure detergent application without a separate injector fitting

The XTA series designation is the critical differentiator that separates this pump from all standard XTV models. Where XTV pumps operate at 3,400 RPM, XTA series pumps are engineered for 1,750 RPM — a purpose-built low-speed platform matched to standard 4-pole electric motor synchronous speed without any gear reduction, belt reduction, or speed-matching hardware. That half-speed operation is not a performance compromise — it is a deliberate engineering choice with measurable consequences for bearing life, seal longevity, heat generation, noise output, and continuous-duty uptime.

Why 1,750 RPM Changes Everything

The Engineering Case for Low-Speed Continuous-Duty Operation

The single most important specification on the XTA3G16EBAF8M2I is not its pressure or flow rate — it is the 1,750 RPM operating speed. Every other triplex pump in this review series runs at 3,400 RPM. The XTA series runs at exactly half that speed, and the downstream consequences of that difference touch every aspect of pump performance, longevity, and total cost of ownership:

• Extended bearing and seal life — bearing fatigue and seal wear accumulate as a function of shaft rotations, not hours alone. At 1,750 RPM, the crankshaft, connecting rod bearings, and plunger seals complete half the wear cycles per hour of operation compared to a 3,400 RPM pump producing equivalent flow and pressure. In continuous-duty applications running 8–16 hours per day, that difference compounds into dramatically longer service intervals and lower annual rebuild costs.
• Reduced heat generation — friction-generated heat inside the crankcase scales with rotational speed. Lower RPM means lower crankcase temperatures, which preserves oil viscosity, reduces thermal stress on seals and o-rings, and eliminates the heat-induced accelerated wear that shortens pump life in continuous-run industrial environments.
• Quieter operation — mechanical noise from crankshaft rotation, valve cycling, and plunger reciprocation all decrease at lower operating speeds. The XTA3G16EBAF8M2I operates measurably quieter than equivalent 3,400 RPM pumps — a meaningful advantage in food processing facilities, customer-facing wash bays, and any environment with occupational noise exposure requirements.
• Smoother water delivery — lower reciprocation speed at each plunger produces longer, more gradual pressure pulses and less instantaneous flow variation, delivering smoother output to downstream accessories including foamers, surface cleaners, hose reels, and chemical proportioning systems
• Direct motor speed matching — standard 4-pole NEMA 56C electric motors run at approximately 1,725–1,750 RPM at full load. The XTA3G16EBAF8M2I is designed to match this speed directly — no belt reduction, gear box, or variable frequency drive is required to achieve the correct pump operating speed from a standard motor

Brass Head, Aluminum Connecting Rods — The BA Specification at 1,750 RPM

Material Engineering Matched to Low-Speed Continuous-Duty Operation

The BA material designation in the XTA3G16EBAF8M2I defines the construction at two critical points in the pump’s architecture — and both choices are particularly well-suited to the 1,750 RPM continuous-duty operating profile:

• Forged brass manifold head (B) — the manifold is where water pressure, temperature cycling, and chemical exposure intersect continuously in an industrial washdown environment. Forged brass provides a dense, pore-free pressure vessel that resists corrosive attack from chlorinated water, cleaning agents, sanitizers, and food-grade detergents used in the facility maintenance and food processing applications where the XTA platform excels. The brass head outlasts cast aluminum manifolds under sustained chemical exposure by a substantial margin.
• Aluminum connecting rods (A) — at 1,750 RPM, the reduced rotational speed already lowers bearing and connecting rod stress compared to higher-speed pumps. Aluminum connecting rods complement this by further reducing reciprocating mass, contributing to smooth crankshaft rotation, lower vibration transmission to the motor and mounting frame, and extended bearing life across years of continuous-duty operation.

The Gymatic Unloader with Integrated Chemical Injector

Pressure Regulation and Detergent Feed for Industrial and Commercial Wash Systems

The Gymatic 3/B unloader (AR20399) on the XTA3G16EBAF8M2I is rated to 3,650 PSI — well above this pump’s 1,600 PSI operating pressure. AR unloader ratings carry an accepted 15% upside variance, and pairing a higher-rated unloader with a lower-pressure pump is deliberate engineering practice: wider stable regulation window, reduced unloader internal wear, and extended service intervals throughout the pump’s life.

Once pressure is set and locked, the Gymatic’s tamper-resistant design holds that setting reliably — making the XTA3G16EBAF8M2I a dependable specification for:

• Managed facility wash stations — pressure configured once by maintenance management and held consistently across shift operators without re-adjustment or drift
• Rental equipment fleets — dealer-set pressure maintained across every rental cycle, preventing over-pressure events and reducing service call frequency
• Continuous-duty industrial installations — fixed wash stations running multiple shifts benefit from unloader stability that does not require periodic recalibration under sustained use

The Gymatic 3/B also delivers:

• Internal bypass operation — trigger-off bypass smoothly redirects flow, preventing deadhead pressure spikes that accelerate seal and valve wear during idle intervals in continuous-run industrial systems
• Integrated downstream chemical injector — the venturi-driven injector built into the unloader body draws sanitizer, detergent, degreaser, or soap from a supply container when the operator switches to low-pressure application mode — essential for food facility sanitation and fleet pre-soak workflows
• Motor load reduction in bypass — reduced back-pressure in trigger-off bypass mode lowers motor amperage draw and heat accumulation, protecting motor windings in continuous-run electric installations
• Brass body construction — resists corrosion from food-grade cleaning chemicals, sanitizers, chlorinated water, and sustained industrial exposure

F8 NEMA 56C Face Mount — Direct 4-Pole Electric Motor Integration

Speed-Matched, Belt-Free, Compact Installation

The F8 flange on the XTA3G16EBAF8M2I provides a close-coupling face-mount interface for NEMA 56C-frame electric motors with a 5/8″ I.D. hollow shaft. At 1,750 RPM, this pairs naturally with standard 4-pole NEMA 56C motors running at full-load synchronous speed — no belt reduction, gearbox, or VFD speed matching required:

• Speed-matched direct drive — 4-pole NEMA 56C motors run at approximately 1,725–1,750 RPM at full load, precisely matching the XTA pump’s design speed for direct shaft coupling without intermediate speed reduction
• Precision shaft concentricity — shared face-mount interface ensures factory-accurate shaft alignment without custom brackets or adjustment procedures
• Minimal installation footprint — compact coupled assembly suits wall-mount frames, utility carts, cabinetized wash stations, and space-constrained industrial installations
• Broad motor compatibility — NEMA 56C is the standard configuration across major US electric motor manufacturers, giving system builders and OEM integrators wide motor sourcing flexibility
• Supplied mounting hardware — bolts and fasteners sized for the F8 bolt pattern are included in the box
