Calculating Maximum Pumping Distance

1. Obtain the maximum horizontal tubing length (L ) from Tables .
2. Take 3% of the maximum horizontal tubing length (L) in meters and multiply the result by the vertical distance (Lvert):

C = 0.03 x (L) x (L vert)

3. Subtract this product (C) from the maximum horizontal tubing length (L) to obtain the maximum pumping distance (Lmax) in consideration of the specific vertical lift:

Lmax = L - C

Note: The result is the maximum pumping distance (Lmax), including horizontal and vertical tubing runs, that is obtainable for the particular flow rate, tubing I.D. and viscosity of syrup specified.
To calculate the losses in the system in feet obtained the maximum horizontal tubing length in feet and multiply by 1% instead of 3%.

Example

1. The tables indicate that heavy soda syrup with 15 ml/sec (1/2 oz./sec) flow-rate (per the example above) can be sustained over a horizontal distance of 152m (500 ft.) when 10 mm I.D. (3/8") tubing is used. Therefore; L = 152 m.
2. C = (0.03 x 152) x 6.7m = 121.5 m
3. Lmax = 152 - 30.5 m = 121.5 m; Lmax = 121.5m

The results indicate a 121.5m tubing length (horz./vert.) is possible, while the example only requires a distance of 113m.

Note: If the example above resulted in a value that was equal to or less than the necessary total tubing run, the installer would need to consider a larger I.D. tubing or installation of a pump(s) in series using the SHURflo Vacuum Regulator.
