Grundfos CVBE/V Mechanical Shaft Seal Kit for CH CHN CHV 2 4 Pumps 96609244 #5150

Grundfos CVBE/V Mechanical Shaft Seal Kit for CH, CHN & CHV 2 / 4 Pumps – 96609244 – #5150

Genuine Grundfos mechanical shaft seal kit 96609244, listed by the manufacturer as CVBE/V for CH(N,V) 2/4. This identifies the CH, CHN and CHV 2 and 4 pump families, subject to the exact pump version and service-part requirements.

The CVB seal specification uses a ceramic and carbon sealing-face combination. CVBE identifies the EPDM elastomer version; CVBV identifies the FKM version. Select the correct sealing materials for the liquid and operating conditions as well as matching the pump itself.

Condition: New and unused surplus stock. Packaging may show storage or handling marks. Please refer to the listing photographs for the actual item, label and components supplied.
Guarantee: Supplied with a 2-year guarantee from The Pump Dealer.
Stock reference: #5150.

Product Details

Compatibility Guidance

Match the replacement to the pump's complete model designation, eight-digit product number and production code. Check the existing seal specification and the pump's service documentation. A CH family name or a CVBE/CVBV code alone does not establish that every service kit with a similar description is interchangeable.

Need help identifying the correct seal? Send us a clear photograph of the pump nameplate and the existing part or packaging label. Call 01803 220416 or email kirk@thepumpdealer.co.uk. Please quote 96609244 / #5150.

Frequently Asked Questions

What does this shaft seal do?

It seals around the rotating shaft where it passes through the pump's stationary housing. It is intended for a seal repair in a correctly matched pump, rather than replacement of the motor or complete hydraulic assembly.

What does CVBE/V mean?

C identifies an O-ring seal whose spring also acts as the drive element. The first V identifies the ceramic rotating face and B identifies the resin-impregnated carbon stationary seat. The final E or V identifies EPDM or FKM elastomers respectively. The position of each letter matters: V has different meanings in the face and elastomer positions.

Does the slash mean that EPDM and FKM are interchangeable?

No. CVBE/V is the manufacturer's combined designation for these material versions. EPDM and FKM have different chemical and temperature capabilities. Fit the specified elastomer for the application. The designation alone does not confirm which loose components are present in an individual pack.

What do CH(N,V) and 2/4 mean?

CH(N,V) groups CH, CHN and CHV in the manufacturer's part description. The numbers identify the 2 and 4 pump sizes. They do not specify the number of seals in the kit, its diameter or a universal two-to-four-stage limit.

Does it fit every CH, CHN or CHV 2 or 4 pump?

Compatibility must be checked for the individual pump. These ranges include different seals, production versions and service arrangements. Match the nameplate details and specified spare part before ordering.

Is 96609244 the same kit as 985164?

Grundfos lists both numbers separately. Its CH/CHN service catalogue identifies 985164 as a seal kit supplied with 11 gaskets and assembly hardware. We have not established an official interchangeability statement or an identical contents list for 96609244. Please check the exact number required.

What components are supplied?

One 96609244 kit with the components shown in the listing photograph. The photograph shows the shaft-seal components, sealing rings and small assembly hardware. Chamber/stage gaskets are not shown. Do not assume that this pack includes the 11 chamber gaskets documented for kit 985164. Contact us if you need a particular additional component.

Can I use it in a CHI or a newer CM pump?

Do not select it on that basis. CHI and CM have their own service-part selections. Grundfos's CH-to-CM conversion guide concerns replacement of complete pumps; it does not establish that their internal shaft seals are interchangeable.

Does the motor voltage determine which seal I need?

Voltage alone is insufficient. This is a mechanical service part, and the relevant checks are the pump construction, seal arrangement, materials and manufacturer part selection. Supply the full pump product number when requesting a compatibility check.

Does direction of rotation matter?

Yes. Grundfos identifies the Type C spring-drive seal as dependent on shaft rotation direction. Follow the rotation marking and service instructions for the exact pump; do not choose a seal purely by its approximate size.

What pressure and temperature can it handle?

The kit designation does not establish a single operating limit for every pump. Use the limits for the exact pump, seal configuration and liquid. Fitting a replacement seal does not increase the pump's original rating.

Will a new shaft seal cure every leak or restore low pressure?

First identify the fault. Leakage from a casing gasket, plug or connection requires a different repair. A shaft seal replacement also does not restore worn impellers or correct a damaged shaft. Inspect the surrounding components and address the cause of the original failure.

Which number should I use when enquiring?

Quote 96609244 for this kit and #5150 for our stock reference. Also provide the pump's own eight-digit product number: that identifies the complete pump and is a different reference from the replacement kit number.

Pump Compatibility – Manufacturer Application

Grundfos lists part 96609244 for the CH(N,V) 2/4 application group. This supports the family description in this listing, but does not provide a complete list of individually confirmed pump product numbers.

An exact pump-number compatibility list has not been established for 96609244. Manufacturer records listing 985164 or another kit have not been presented here as confirmed matches for this part. Please contact us with your pump's full nameplate details before ordering if you are matching by pump model rather than an existing 96609244 part number.

Technical descriptions are based on the manufacturer references linked above. Final selection and installation should follow the service requirements for the exact pump and its installed configuration.
