Cornelius Cold Beverage Dispenser manual Pumps in Series for Long Distances

IntelliCarb Training Manual

The chart indicates that heavy syrup with 1/2 oz./sec [15mL] flow-rate (per the illustration) can be sustained over a horizontal distance of 500 ft. [152M] when 3/8" I.D. [10mm] tubing is used.

Feet: Take 1% of 500 ft. (500 x 1%) = 5. Which then is multiplied by the 22 ft. vertical, (22 x 5) = 110 ft.

Subtract this product from the 500 ft. (500 - 110) =390. The results indicate a 390 ft. tubing run (horz./vert.) is possible, while the example only requires a distance of 370 ft.

Meters: Take 3% of 152M (152 x 3%) = 4.56. Which then is multiplied by the 6.7M vertical, (4.56 x 6.7) = 30.5M.

Subtract this product from the 152M (152-30.5)=121.5. The results indicate a 121.5M tubing run (horz./vert.) is possible, while the example only requires a distance of 113M.

NOTE: Had the example above resulted in a value that was equal to, or less than the nec- essary total tubing run, consider a larger I.D. tubing or installation of a pump(s) in series using a SHURflo Vacuum Regulator.

Pumps in Series for Long Distances

Long tubing runs or high vertical lift can be achieved by installing pumps in series. Standard SHURflo Beverage pumps are not designed to have positive pressure on the inlet side. The SHURflo Vacuum Regulating Valve (VRV) allows the pump to receive liquid from a pressurized source. By positioning a VRV at the inlet of the secondary pump, incoming pressure is reduced to zero, permitting syrup to be drawn in under vacuum.

SHURflo can recommend several other methods to meet the requirements for a particular installation, including Pressurized Inlet Pumps or Accumulators. Contact SHURflo for more information.

Pump Sanitizing / Winterizing

Sanitization of the SHURflo Beverage Gas Pump is required. The frequency of Sanitization is dependant on the concentrate type and its manufacturer’s requirements. Factors which also affect the frequency of this procedure are: temperature, concentrate volatility, facility conditions, installation and equipment. The sanitizing procedure fulfills a required 10 minute contact time with a 200 ppm Sodium Hypochlorite solution. Refer to SHURflo Service Bulletin #1025 for the N.S.F. listed sanitizing procedure for the SHURflo pump (only). Pumps that are subjected to freezing (below 32° F [0°C]) must be purged of fluid to prevent damage. Refer to SHURflo Service Bulletin #1025 for complete winterizing procedure. Refer to the equipment manufacturer’s instructions for sanitizing and winterizing procedure for carbonators, dispensers and tubing.

Pumps that have been winterized and/or out of service for a period of time should be sanitized prior to being placed back in service.

Never apply pressure to the pump’s liquid inlet. Pressurized tanks may damage internal components if used to sanitize or purge fluid from the pump (operating or not).
