HYD-WHWLSS4115 Hydraulic Pump | 10.8 GPM 2200 PSI SS

HYD-WHWLSS4115 | Hot Water Stainless Hydraulic Pump | 10.8 GPM 2200 PSI

HYD-WHWLSS4115 stacks the three specifications that industrial sanitation writes into every bid: hot water capability, a stainless steel head, and serious flow. Built on Annovi Reverberi’s WHWL hot-water version of the proven XWL frame, it delivers 10.8 GPM (41 L/min) at up to 2200 PSI (150 bar) at 1450 RPM in hydraulic-drive configuration — heated washdown volume powered from a facility or vehicle hydraulic system, with wetted surfaces that survive both the temperature and the chemistry.

Heat is the point. Hot water does what cold water and pressure alone cannot: it melts fats, cuts grease, releases proteins, and lifts waxes at a fraction of the dwell time — which is why food processing, rendering, dairy, and meat facilities sanitize hot as a matter of regulation and physics alike. The stainless head closes the loop, standing up to the chlorinated sanitizers, caustics, and acid rinses that follow the hot cycle in every food-grade washdown program. The HYD-WHWLSS4115 is the pump that specification converges on.

Why Hot + Stainless + Flow Belong Together

Run the three specs separately and each solves half a problem. Hot water without corrosion-resistant wetted parts eats standard heads from the inside — elevated temperature accelerates every chemical attack the sanitizer chemistry brings. Stainless without heat leaves the grease-cutting to chemicals and dwell time, slowing every wash cycle. And either without flow turns plant sanitation into an all-night shift. The HYD-WHWLSS4115 runs all three at once: 10.8 GPM of heated water clearing fats and soils at production speed, through a head that treats caustic, chlorine, and acid cycles as routine. For facilities audited on sanitation, that is not a premium option — it is the correct tool.

Hydraulic Supply Requirements

Plan on roughly 20 hydraulic horsepower delivered continuously for full duty. In this frame class, AR’s published pairing pattern runs a 22cc gear motor on approximately 37 L/min (9.8 GPM) of oil at up to ~227 bar (3,290 PSI) — the fit for plant power units and strong vehicle circuits — with larger-displacement, lower-pressure pairings available where the circuit is flow-rich instead. Size any motor to reach 1450 RPM via RPM ≈ 231 × hydraulic GPM ÷ displacement (in³), verify torque at working pressure, cap the circuit with a relief protecting the motor, and provide return filtration and oil cooling for sanitation-shift duty. Call WSHPWR with your circuit’s flow and pressure and we will spec the motor and confirm the match.

Built for Sanitation Duty

Sanitation work is repetitive by design — the same circuits, the same chemistry, the same hours, every production day. The 194-series frame underneath carries ceramic plungers for heat and abrasion resistance, a crankcase engineered for daily continuous duty, and in-place valve access so routine inspection fits inside a sanitation window instead of consuming one. Hydraulic drive keeps motors, fuel, and exhaust out of wet processing areas entirely — one more thing the auditor never has to question.

Installation & Operation Notes

Confirm your drive configuration and rotation at commissioning, and mount horizontally. Feed the 3/4″ inlet from a flooded, filtered supply — and respect the physics of hot inlet water: elevated temperature lowers the cavitation margin, so suction plumbing that passes with cold water can starve the pump hot. Keep suction lines short, generous, and unrestricted. Pair the discharge with an unloader set against working pressure, size nozzles to the 10.8 GPM duty point, rinse the system after chemical cycles as good practice even with stainless, hold 1450 RPM, and winterize any unit exposed to freezing.

Quality Assurance & Maintenance

Every HYD-WHWLSS4115 ships factory-tested for flow rate, pressure stability, and vibration. Maintenance follows AR’s standard schedule — crankcase oil changes, seal inspection, periodic valve checks with AR repair kits — with hot-water duty rewarding oil-change discipline, and the stainless head removing corrosion from the wear equation across every chemical cycle it sees.
