Are KSB pumps UL listed. Second, should I go for a split case or end suction (horizontal) for delivering 750gpm in a fire sprinkler network. Thanks

Some are.

Option 1: Contact KSB and ask about the particular pump you may want.

Option 2: Click this -- UL Online Certifications Directory

Enter KSB in the company name field, and search.

Open each file number and have a look -- see if your pump is listed.

Best to you,

Goober Dave

Pumps that are UL listed and become part of a Fire Protection system should be specified, designed, certified and tested to NFPA-20

There are many US vendors of these UL/NFPA certified pumps......

Tell us more about what you are trying to do........

Dear DWeig, it's quite a process to find your product out from the site link you have provided. Do you recall the ones which are UL listed, as you said some are. Thanks for your input anyway.

Dear Cronin,
I am reviewing a material submittal. As per specs we are only supposed to approve UL listed manufactured to NFPA 20 pumps. Now as contractor has submitted KSB, and it's not clear whether it is UL listed so just wanted to know from seniors like you if these are UL listed or not.

Unless you are located in Argentina or Canada, there probably is not a KSB UL listed pump that is available to youf. It doesn't appear that KSB makes a UL end suction pump.

Good job bimr, but at the bottom it says that appearing company name here doesn't certify that this particular company is making products that are UL listed, instead we need to look for the UL mark on the product:(
I am reviewing pumps made in KSB Germany and Holland. Would you be kind enough to get me any UL directory page for the same KSB pump. Appreciate your help.

To avoid wasting time on this, where is the project located? Historically, the UL label was used for products manufactured in the US. There are other "UL" labels for products manufactured in Europe and elsewhere.

For example, the D Mark is a voluntary safety Mark registered and provided by UL International Demko A/S. It has been in use for more than 70 years and is a familiar symbol to consumers, retailers and manufacturers in Europe.

Regarding "instead we need to look for the UL mark on the product:(". Shop drawings are reviewed 3-4 months prior to accepting product delivery, so how do you plan to see the mark? Maybe you should plan an inspection trip.

It may be easier for you to have the manufacturer certifies that the product is UL listed (or whatever approval that the owner and AHJ requires for the completed system) prior to issuing the purchase order.

Note that on some fire pump installations, acceptance is based on the overall installation of the fire pump system, not just the individual product certification of the fire pump. It depends on the AHJ's requirements.

Here, Hasni2:

If it's not listed in this chart or the one attached to my next reply, it's not supposed to bear the UL label. For the information you are requesting (whether the pump you would like has a label), you must ask KSB. There is no directory from UL that confirms labels. The purpose of the pages that bimr so kindly attached is to confirm that a UL-labeled product is indeed in the UL database.

The two listings that bimr attached are the only ones that UL has under the name KSB.

It's time to contact KSB for your answers.

Best to you,

Goober Dave

And I have seen products that said they were UL listed - when only the plug and cord were actually tested??
