XMVSS35G25E-F33 | 3.5 GPM 2500 PSI Pump 3400 RPM SS 5/8 Shaft

Overview

The Annovi Reverberi XMVSS35G25E-F33 is a stainless-steel head,
industrial-duty triplex plunger pump designed for demanding high-pressure
applications where corrosion resistance and long service life are critical.
Rated for 3.5 GPM at 2,500 PSI and engineered to run up to
3,400 RPM, this electric-flange model is ideal for compact,
high-performance wash systems, process cleaning skids, and OEM installations
that need reliable 24/7 operation in harsh environments. With a
5/8″ hollow “E” shaft and F33 electric motor flange,
it couples directly to compatible electric motors for a clean, space-saving
package. :contentReference[oaicite:0]{index=0}

• Stainless-steel (SS) head version of the XMV series for superior corrosion resistance.
• Delivers 3.5 GPM at 2,500 PSI for serious cleaning power in a compact footprint.
• High-speed operation up to 3,400 RPM for direct-drive electric systems.
• 5/8″ hollow E-shaft with F33 flange for NEMA 56C-style electric motors.

Performance and Pump Design

As part of AR’s XMV/XM stainless commercial family, the XMVSS35G25E-F33 combines
a three-piston volumetric design with premium materials to deliver smooth,
consistent pressure at higher speeds. The triplex plunger arrangement reduces
pulsation, improving operator control and protecting downstream hoses, guns,
and rotating nozzles. Its 3.5 GPM duty point is ideal for single-gun systems
that need strong impact force without excessive water consumption.

• Max flow: 3.5 GPM – sized for single-gun commercial use.
• Max pressure: 2,500 PSI – excellent for tough soils, grease, and road film.
• Max speed: 3,400 RPM for compact direct-drive packages. :contentReference[oaicite:1]{index=1}
• Duty class: industrial triplex plunger, designed for continuous or frequent use.

Triplex plunger architecture

The heart of the XMVSS35G25E-F33 is a crank–connecting rod system driving three
one-piece ceramic plungers. This architecture provides a stable, predictable
pressure curve that is easy on accessories and helps maintain consistent spray
patterns, even when line length or nozzle sizes vary.

• Three synchronized ceramic plungers minimize pulsation and hose “kick.”
• Crankshaft in high-strength steel with oversized bearings for long life. :contentReference[oaicite:2]{index=2}
• Optimized internal porting for reliable inlet feeding and priming.
• Compatible with unloaders, regulators, and safety valves for precise system control.

Stainless Wet-End Construction

The “SS” designation identifies this as a stainless steel head
variant, engineered for environments where traditional brass heads may suffer
from chemical attack or aggressive wash chemistry. AR’s stainless commercial
pumps use an AISI 316L stainless head with corrosion-resistant internals,
matched to a durable die-cast aluminum crankcase. :contentReference[oaicite:3]{index=3}

• Head material: AISI 316L stainless steel manifold for superior corrosion resistance.
• Body & covers: die-cast aluminum with protective coating and cooling fins.
• Plungers: one-piece solid ceramic plungers for maximum wear resistance.
• Valves: stainless steel valve assemblies designed for high-pressure cycling.
• Sealing system: double gasket / packing design to keep water and oil separated. :contentReference[oaicite:4]{index=4}

Corrosion-resistant advantages

Stainless head construction makes the XMVSS35G25E-F33 a strong choice for
aggressive or corrosive environments, including saline atmospheres and certain
chemically assisted cleaning applications (within AR’s chemical compatibility
guidelines).

• Ideal for food and beverage plants and USDA-compliant washdown.
• Well suited to coastal facilities and marine yards exposed to salt air.
• Excellent for chemical plants, recycling centers, and waste management sites.
• Supports longer service life where standard brass heads might pit or discolor.

Drive, Mounting, and Integration

The “E-F33” configuration refers to a 5/8″ hollow electric shaft
paired with an F33 electric motor flange, allowing the pump to
mount directly to a NEMA 56C-style frame motor. This eliminates belt alignment
in many systems and keeps the overall package compact—an advantage for OEMs,
skid builders, and cabinet-style machines. :contentReference[oaicite:5]{index=5}

• Direct-drive interface to 56C-frame electric motors using the F33 flange.
• 5/8″ hollow shaft for efficient power transfer and compact layout.
• Standard right-hand drive orientation for straightforward system design.
• Oil-bath crankcase with sight glass and drain for quick maintenance checks.

Serviceability

Like other XMV series pumps, the XMVSS35G25E-F33 is designed so technicians can
access valves, seals, and packings with standard tools. Factory repair kits
bundle common wear items so rebuilds are predictable and downtime is minimized.

• Standardized valve, water seal, and oil seal kits available through AR distributors.
• Side oil sight glass and fill/dipstick for easy oil-level monitoring.
• Intake and delivery valves with threaded plugs for straightforward inspection. :contentReference[oaicite:6]{index=6}

Typical Applications

With its 3.5 GPM / 2,500 PSI stainless-steel construction, this pump is aimed
at professional users who need both high performance and resistance to corrosion.

• Food, meat, and dairy plants – sanitation lines, equipment washdown, and floor rinse.
• Chemical processing and environmental services – equipment cleaning and containment pad wash.
• Fleet and rental operations – trucks, refuse vehicles, tankers, and equipment wash bays.
• Marine & coastal facilities – boat yards, ports, and coastal maintenance shops.
• Manufacturing and recycling plants – conveyor, bin, and compactor cleaning.
• Contractor and OEM skid builds – compact electric-driven industrial pressure washers.
