FLOW CART SPECIFICATIONS

The fabricated Flow Cart will support a flow meter, a valve manifold, and an electrical panel. The cart

assembly will be portable with a provision to lock it in position when it is in use. No provision will be

made to level the cart or to slope the lines. The weight of the flow meter is estimated at 50 kg, and the

weight of the electrical panel is estimated at 150 kg. The outlets from the valve manifold will be

connected to 2” flexible hoses and will need to support the weight and bending moments generated by

these in normal use. The cart will be operated in an FDA regulated production area. Detailed design

and fabrication should comply with 3A and pharmaceutical clean design practices.

The piping will be fabricated from 316L stainless steel sanitary tubing with an internal surface finish of

30 micro-inches Ra or better with standard tri-clamp end connections. The supporting frame will be

fabricated from 304 stainless steel with a No. 4 brushed finish on exposed surfaces. Welds will be

ground smooth and sharp edges and corners broken. Exposed threads will be capped.

Attachments:

- Dimensioned concept sketch: this sketch shows the critical dimensions of the flow cart and the

arrangement of components on the cart. Support structure for the components is not shown and is to

be designed by the fabricator.

- Component ‘cut sheets’: manufacturers’ cut sheets are included for the hand valves (HV 1, HV

2, HV 3, HV 4) and the flow meter. These components will be provided to fabricator for assembly when

they become available.
