Salient Features and Benefits of Jupiter Worm Drive Clamps:

Particulars Advantages to
Assembler User End User
Direct Indirect
Highest clamping range for emergency use at alternative smaller size applications and thus reduces inventory.
   
Wider tolerance allowable on hose thickness and insert tube reduces expenses of mating parts.    
Vibration-proof quality by Worm Drive Principle avoids risk of leakage and Warrantee claims & gains goodwill.
 
High clamping pressure with low tightening torque provides convenience at Assembly.
  
High band flexibility adjusts itself to suit the shape of mounting hose & its deflected inserts.
   
Corrosion resistance by use of S. S. avoids periodic repurchases.
    
Omission/minimum use of Zinc Plating helps to follow Environment Protection Norms.    
Provision of high safe torque strength values assures safety against dangerous slippage causing total loss of clamp, coolant, engine performance and thus avoids warrantee claims and adds to goodwill.

Uniform radial clamping pressure all over the hose engagement area enhances leak - proof quality and hose life.
Withstands climatic fluctuations from hot to below 0 c with leak - proofness. (Ref : Type JW 7 D)
 
Saves non-clamp expenses of non-standard crimpling installation tools required for certain designs. Avoids problems of non-availability of such tools at fieldwork.
Uniformly distributed pressure by Jupiter on wider hose area by strip type band increases hose life unlike clamping by wires, which penetrates the same and reduces hose life. The indirect benefit of strip band is thus transferred to hose. This is very true for soft surfaces of precious Silicon hoses or costly coolant connections.
 
Longest life of Jupiter avoids repeated inflationary purchase cost with O.H. suffered by the end-user caused by short life clamps.

Identification Code Nos (Types) :


In order to differentiate the applications / designs, Jupiter clamps generally have their own
identification type codes.

 



Illustrations :

Type JW 6 B : All Stainless Steel Clamps
For normal environmental or Water contamination applications, AISI 201/202 material is used.

Type JW 7 B : All Stainless Steel Clamps
These are high strength clamps for general Salt Water or chemical applications made out of AISI 304 material.

Type JW 8 B : Acid-proof Clamps
This is special type with use of AISI 316 for high corrosion resistance as Acid - Proof applications.

Type JW C : Clamps with underlap
For more protection of hose, underlap beneath the band threads is provided on demand.

Type JW D : Constant Torque Clamps
These types are more vibration-proof under severe conditions. They also withstand for Hot and Cold climatic fluctuations by automatic self adjustment of clamp dia as the nature demands.

Type JW E : Snap Action Clamps
These are snap action clamps specially developed for applications when frequent or periodical re-opening is required. They are generally long ranged clamps to facilitate quick easy mounting for variable application sizes.

Type JW F : Worm Drive Thumb Screw clamp
Clamps with built-in Screw flap is provided if required for quick closing & opening operations without tool.

Special Type : Worm Drive V-Clamps
These clamps are used for light connections of V-type jointing of flanged pipes for peculiar requirements.

Special Designs :

Apart from above, Jupiter Clamps are also available with special specifications as per customers requirement.

ORDERING INFORMATION :

For smoother services the following points may please be noted by the customer while ordering :
  • Clamp DIA means Max Dia of the clamp to suit the OUTSIDE Dia of the mounting hose.Use of mere term Hose Dia (if means INNER Dia) is confusive and should be avoided.
  • The customer should go through all above literature and decide the necessary type of Jupiter design for his use.
  • While enquiring, customer may call for Jupiter Questionnaire to decide or design specific clamps for P.No. applications. Accordingly prototype drawing shall be prepared and submitted for Customer's convenience & approval.
  • Customer is requested to attend Jupiter's Receipt of Order Form for amendment if any.
  • E-mail correspondence should be complete with full address, P.P., Communication Nos. and other specific details of the sender.
