Frequently Asked Questions -
Selecting a Separator


Q: How do I select the proper separator?

A: Proper separator selection relies on the following questions being answered: 1) Flowrate; constant minimum, maximum, or variable? 2) Allowable pressure drop? 3) Connection; thread or flange? 4) Contaminates to be removed? 5) Maximum operating pressure? 6) System fluid? 7) Installation type; full stream, side stream, basin or sump? 8) ASME requirement? 9) Installation size constraints; height, footprint? 10) How to dispose of solids?



Q: I have a constant flowrate; how do I size?

A: Separators will work well within a large flowrate range for each size available. Choose the model that is at or above a 6 psi drop.



Q: I have a variable, low flowrate; how do I size?

A: Separators will work well within a large flowrate range. However, if your flowrate has a pressure drop of less than 4 psi you must consider the following: 1) Operating below a pressure drop of 4 psi reduces separation efficiency. At 6 psi efficiency is 97%, at 4 psi 94%, at 3 psi 85%. 2) What is your percentage of operation below 4 psi, is this percentage significant? 3) If your variable flowrate is due to different pump cycling, is it possible to install several separators instead of one large one?



Q: I have a variable, high flowrate; how do I size?

A: Separators will work well within a large flowrate range. However, if your flowrate has a pressure drop of more than 10 psi you must consider the following: 1) Operating above a pressure drop of 10 psi increases pump horsepower requirements significantly. It may be advantageous to use the next larger separator. 2) What is your percentage of operation above 10 psi, is this percentage significant?



Q: Can I use a threaded connection separator on my flanged piping?

A: J.L. Wingert offers both threaded and flanged connection separators. A threaded separator can be mated with "threaded" flanges to adapt it to flanged piping. However, it is usually easier to match same connections.



Q: I have a cooling tower, for my HVAC system do I require anything special?

A: Contaminates in most cooling towers are either airborne, rust from pipes, or limescale from water evaporation. These contaminates are considered "soft" and not a threat to carbon steel. In this application you can use either a self-contained separator system, to clean tower basin, or a standard separator.



Q: My application is greater than 150 psi; what do I do?

A: J.L. Wingert can design separators for operating pressures that exceed 150 psi. Please request a quotation for your special requirements.



Q: I have an aggressive fluid with contaminates?

A: For other than "water" uses J.L. Wingert offers fabrication from stainless steel, either 304 or 316. Please request a quotation for your special requirements.



Q: My requirement is for ASME design and construction; can J.L. Wingert help?

A: J.L. Wingert can provide an ASME separator. Please request a quotation for your special requirements.



Q: I don't have much floor space; what do I do?

A: Angle mounting drastically increases the installation footprint. J.L. Wingert units are repeatedly shorter than other designs. Frequently we can fit vertically, and reduce installation cost with a smaller footprint.



Q: Solids can't go down the drain; what do I do?

A: Two methods of contaminate handling are available: 1) J.L. Wingert offers "manual" or "automated" purge systems that send contaminates down the drain, like a sand filter. 2) If drain flow is a problem, we can save all the fluid by trapping the solids in a recovery tank and return the fluid to the system.
