311AX4
311AX4 — Belt Driven Power Washers with Triplex Pump
BUILT FOR SERIOUS OPERATORS.
Alkota 311AX4 is an industrial-grade hot water cleaning system engineered in South Dakota by Alkota and built for the demanding conditions of UK commercial and industrial operators. Delivering 76 bar (1100 PSI) at 11.4 L/min (3 GPM), it features Alkota's signature heavy-gauge welded chassis and precision-engineered oil bath crankcase|triplex ceramic plunger.
Built for intensive continuous duty, the Alkota 311AX4 combines high-efficiency heat exchange with industrial-grade mechanical components. Alkota's proprietary coil technology features a hydro-insulated cold-water wrap that protects operators, pre-heats incoming water, and eliminates thermal shock — backed by a 7-year warranty.
Oil Bath Crankcase
Oil-bath crankcase and ceramic plungers running at lower RPM for cooler, vibration-damped longevity.
Schedule 80
Hydro-insulated cold water wrap pre-heats water, protects operators, and eliminates thermal coil stress.
7-Year Coil Warranty
The benchmark in industrial heating reliability. While competitors offer 1–2 years, Alkota guarantees 7.
Welded Steel Chassis
Heavy-gauge welded structural steel frame with powder coat finish built to survive demanding site environments.
