Car Wash Equipment → Pressure Washer Pumps
JBS professional pressure washer pumps provide HAWK and Annovi Reverberi solutions for commercial car washes, self-service wash bays and high-pressure cleaning systems. Select the correct pump by matching pressure, flow rate, RPM, motor power, shaft configuration and mechanical compatibility with the existing machine.

Category Guide
A commercial pressure washer pump should be specified as part of a complete high-pressure system, not purchased on PSI alone. Professional car washes, self-service bays, fleet-cleaning sites and industrial cleaning systems depend on the correct combination of pressure, flow rate, pump speed, motor power, shaft configuration and unloader setup.
The JBS HAWK NHDP-200 Pressure Washer Pump provides a 200-bar maximum pressure rating and 30 L/min flow capacity. Its professional piston-pump construction, ceramic plungers and brass pump head make it relevant where higher water delivery is required in commercial vehicle-washing and compatible high-pressure systems.
The AR Annovi Reverberi Pressure Washer Pump offers a different operating profile. The current JBS specification lists 275 bar, 15 L/min and 1450 rpm, making it important to compare the actual application rather than assuming the pump with the higher pressure figure is automatically the better choice.
Flow Rate Matters as Much as Pressure
For commercial cleaning, pressure helps break contamination from the surface while water volume helps move loosened dirt away. This is why professional buyers normally compare bar/PSI and L/min/GPM together.
Pump speed also directly influences delivered flow in positive-displacement piston pumps. A replacement pump therefore needs to match the drive system, whether it is direct-coupled to an electric motor or driven through pulleys or another transmission arrangement.
The shaft diameter, keyway, rotation direction, inlet/outlet ports and unloader configuration must also match the existing machine. Buying a pump with the correct PSI but the wrong mechanical interface can create a costly installation problem.
Explore the full JBS Pressure Washer Pump range. Where the existing pump can be economically rebuilt rather than replaced, review Pump Spare Parts for compatible service components.
For new system design, pump selection should be checked against the intended Car Wash Machine or self-service installation before the motor, nozzle and pressure-control system are finalised.
Start with the existing pump nameplate. Record manufacturer, exact model, rated pressure, flow, RPM and any part numbers before searching for a replacement.
Compare flow and pressure together. More PSI does not compensate for inadequate water flow. Select around the cleaning task and expected throughput.
Calculate the required motor power. The drive must be capable of delivering the pump’s required power at the selected pressure and flow without continuous overload.
Match pump RPM. A pump rated at 1450 rpm should not automatically be treated as interchangeable with a differently rated pump. Changing shaft speed changes pump flow.
Confirm shaft compatibility. Check shaft diameter, keyway, rotation, coupling and mounting arrangement.
Check the unloader and nozzle. The pump, pressure regulator, hose, spray gun and nozzle must operate as one hydraulic system.
Review inlet-water conditions. Adequate supply flow and clean, filtered water help protect valves, seals and ceramic plungers.
Consider temperature and chemical compatibility. Hot-water and specialist applications may require pump materials and seals designed for those operating conditions.
Assess rebuildability and parts support. Professional pumps are working assets. Seals, valves, plungers, manifolds and unloaders should be serviceable and obtainable.
Do not buy on brand alone. HAWK and Annovi Reverberi both offer professional pump technology; the technically correct option is the one that matches the machine and duty profile.
The right pressure washer pump is the one whose flow, pressure, RPM, shaft and power requirement match the complete system.

No. Pressure, water flow rate, rotational speed, shaft, connection, and motor-power compatibility must be checked.
The choice should be based on the existing machine's technical specifications, operating duration, and service and spare-parts requirements.
No. Complete pumps should be listed as equipment, while internal components such as seals, valves, and pistons should be listed as spare parts.
