A Great Way to Fill the Piping Systems – Cooling Tower Pumps and Piping – Part 9

Norm HallCooling Towers, Piping and Pumps, Cooling, Cooling Towers, Monday Morning Minutes, Hydronic System Design

The Xylem Bell and Gossett manual TEH-1209 has a great detail for filling the tower water system piping. Many times the cooling tower pump is used to take water from the tower pan and fill the condenser and piping system. This can lead to pump problems due to the large flow rate of the pump compared with…

Pump Suction Piping Rules – Cooling Tower Pumps and Piping – Part 8

Norm HallMonday Morning Minutes, Pumps, Cooling Towers, Hydronic System Design, Cooling Towers, Piping and Pumps, Cooling, Cooling Towers

Traditional hydronic piping system designers use tools such as the Xylem Bell & Gossett System Syzer for pipe sizing. You may find this program at http://completewatersystems.com. Tower manufacturers, the Hydraulic Institute (HI), and Bell and Gossett all suggest lower velocity for pipe selection in cooling tower pump suction piping. Bell and Gossett has several pipe sizing suggestions…
