Goulds Water Technology, Bell & Gossett, Red Jacket Water Products, CentriPro Wastewater Terms and Usable Formulas The term “head” by itself is rather misleading. It is commonly taken to mean the difference in elevation between the suction level and the discharge level of the liquid being pumped. Although this is partially correct, it does not include all of the conditions that should be included to give an accurate description. ■ Friction Head: The pressure expressed in lbs./sq. in.

Goulds Water Technology, Bell & Gossett, Red Jacket Water Products, CentriPro Wastewater Sewage Control Panels and Switches There are two basic switches used in sewage and effluent systems. Single-action or narrow-angle float switches perform one function (on or off). They operate over a range of 15º. Wide-angle, or double-action float and diaphragm switches perform two functions (on and off). Wide-angle float switches operate over a 90º range and diaphragm switches on a 6” rise in water level.
Wastewater Goulds Water Technology, Bell & Gossett, Red Jacket Water Products, CentriPro We sell and stock a complete line of wastewater float switches. The most up-to-date information is found in the wastewater catalog Electrical Section. The switch bulletin is coded as BCPFS, i.e. Bulletin CentriPro Float Switches.
