This unit is completely self-contained and is fully equipped with all necessary instruments, controls and connecting hoses.

All Components are housed in an all steel cabinet of welded and bolted construction. Doors are provided to allow instant access to the interior of the machine for periodic inspection and service. The unit is compact, lightweight, and mounted on rubber tire wheels. Power supplied by a air operated pump. Hydraulic pressure is controlled by means of air pressure regulator. Once the required outlet pressure has been set, the unit can be started and stopped by means of an air shutoff valve. Direction of flow is controlled by a four-way selector valve. Our relief valve is installed in the hydraulic circuit to prevent any excessive pressure build-up. American Lab Systems version of S404.

This unit may be furnished with either a single or a dual outlet system. A suitable service manual containing maintenance and operating instructions is provided.
