A.R. NORTH AMERICA

A.R. North America is a manufacturer of pumps and fluid-system components for high-pressure cleaning and industrial fluid handling. The company's product line centers on triplex piston pumps, unloader and pressure-relief valves, and related accessories used in pressure-washer and fluid-transfer systems. A.R. North America products are commonly specified by original equipment manufacturers, maintenance departments, and service companies that require standardized mounting interfaces and predictable hydraulic performance. The pumps are typically built with oil-bath lubrication, solid or hollow shafts, and flanges that mate to horizontal gas engines or electric motors. Flow rates across the line range from approximately 3.5 gpm to 5.5 gpm at speeds around 1,450 to 1,750 rpm, with intake and discharge connections in FNPT and NPT configurations. Unloader valves in the range include brass bodies with 3/8-inch NPT bypass connections and maximum fluid temperature ratings up to 190°F, as well as commercial-duty relief valves rated to 4,060 psi. These components are used to regulate system pressure, divert flow when a set point is exceeded, and protect downstream equipment from overpressure. 3G Electric supplies A.R. North America pumps and valves as part of its industrial-equipment catalog. The line includes direct-drive, belt-driven, and hydraulic pump models, along with unloader valves and pressure-relief valves. 3G Electric maintains stock across multiple SKUs and supports technical buyers with part-number cross-referencing, specification confirmation, and quotation for single units or volume orders. Because the products are used in pressure-washing, car-wash, agricultural, and general industrial cleaning applications, the catalog is organized to help maintenance and procurement teams match pump flow, pressure, shaft type, and mounting flange to the intended drive. For plant engineers and maintenance managers, the relevant selection criteria are typically maximum flow rate, maximum pressure, inlet and outlet connection sizes, shaft type (solid or hollow), flange pattern, lubrication method, and fluid temperature limits. A.R. North America publishes these specifications per model, and 3G Electric lists them at the SKU level so that buyers can verify compatibility before ordering. The unloader valves are available in brass with NPT threads, and the pressure-relief valves carry commercial-use ratings. Pumps are configured for horizontal gas engine direct-drive mounting, with oil-bath lubrication as a standard feature across the models shown. 3G Electric ships these products globally and provides quotation support for both standard catalog items and repeat-order quantities. The company's role is as a distributor: it holds inventory, confirms specifications against the manufacturer's data, and coordinates delivery. For buyers specifying A.R. North America components, the practical path is to identify the required flow and pressure at the intended drive speed, confirm the shaft and flange interface, and select the corresponding unloader or relief valve for the system's bypass and overpressure protection. 3G Electric's catalog lists the manufacturer part numbers, connection types, and ratings needed to complete that selection.

Frequently asked questions

Common questions about A.R. NORTH AMERICA from 3G Electric.

What is the maximum flow rate available in A.R. North America horizontal gas engine direct-drive pumps?

The A.R. North America horizontal gas engine direct-drive pump models listed by 3G Electric cover maximum flow rates from approximately 3.5 gpm to 5.5 gpm. Specific examples include a 3.5 gpm model at 1,750 rpm, a 3.96 gpm model at 1,450 rpm, a 4 gpm model at 1,750 rpm, a 4.2 gpm model at 1,750 rpm, and a 5.5 gpm model at 1,750 rpm. Flow rate depends on the model and the drive speed. Buyers should confirm the required flow at the actual operating rpm of the engine or motor being used, since the published ratings are tied to specific speeds.

What is the difference between the A.R. North America VHP39 and SVT28 valves?

The A.R. North America VHP39 is a brass unloader valve with a 3/8-inch NPT bypass connection and a maximum fluid temperature rating of 190°F. It is used for bypass regulation, diverting flow when system pressure exceeds a set point. The A.R. North America SVT28 is a brass pressure-relief valve rated for commercial use with a maximum operating pressure of 4,060 psi and an overall height of 4 3/8 inches. The VHP39 is oriented toward bypass control in a pressure-washer circuit, while the SVT28 is oriented toward overpressure protection. Both are brass-bodied and use NPT threads.

Do A.R. North America pumps use solid or hollow shafts?

A.R. North America horizontal gas engine direct-drive pumps are available with either solid or hollow shafts, depending on the model. For example, the RKA4G40HN-PKG and several other models use a solid shaft, while the RRA55G26E-F17 and RRV4G40HD-F24-PKG use a hollow shaft. The shaft type determines how the pump couples to the engine or motor, so it must be matched to the drive interface. 3G Electric lists shaft type at the SKU level so buyers can confirm compatibility before ordering.

What lubrication method do A.R. North America triplex piston pumps use?

The A.R. North America horizontal gas engine direct-drive pressure washer pumps listed by 3G Electric use oil bath lubrication. This means the crankcase contains an oil reservoir that lubricates the moving components during operation. Oil bath lubrication is a standard feature across the models shown, including those with solid shafts and hollow shafts. Maintenance intervals and oil specifications should be confirmed against the manufacturer's documentation for the specific model, as requirements can vary by pump size and duty cycle.

What connection sizes are used on A.R. North America direct-drive pumps?

A.R. North America horizontal gas engine direct-drive pumps use FNPT intake and NPT discharge connections. Connection sizes vary by model. For example, one model uses 1/2-inch FNPT intake and NPT discharge connections, while others use different sizes depending on flow rate and port configuration. The unloader valve VHP39 uses a 3/8-inch NPT bypass connection. Buyers should verify the intake and discharge sizes against the system plumbing before installation, since mismatched connections require adapters.

Can 3G Electric supply A.R. North America pumps and valves for volume orders?

Yes. 3G Electric supplies A.R. North America pumps, unloader valves, and pressure-relief valves as part of its industrial-equipment catalog and supports quotation for both single units and volume orders. The catalog includes direct-drive, belt-driven, and hydraulic pump models, along with the associated valves. For volume orders, buyers can provide the manufacturer part numbers and required quantities for a quotation. 3G Electric ships globally and can coordinate delivery based on the destination and order size.
