Daiphragm Seal

Product Details:

The Nilkanth Enterprise  flanged diaphragm seal uses a diaphragm welded directly to the assembly flange, eliminating much of the cost associated with bulky lower housings made from exotic and expensive wetted materials. The flush-mounted diaphragm prevents clogging and is available in a full range of metallic and coated materials.

Key Features:

• Flush design minimizes the use of expensive specialty wetted materials
• Flush-mounted diaphragm prevents clogging of process media
• Diaphragm welded to flange
• Filling port in the instrument connection
• Suitable for pressure gauges, switches and transmitters

Specifications:

• Flange size: 1″ to 6″
• Flange rating: 150 to 2500 – class flanges
• Flange design according to ASME B16.5

Process Market:

• Oil and Gas
• Refineries
• Chemical and Petrochemical
• Water and Wastewater

Process Applications:

• Oil and Gas Fracking
• NACE Compliant Processes (Sour Gas Separation)
• Biogas and Biodiesel

Product Details:

truncated flanged diaphragm seal model DT protects pressure measuring instruments on isolated pipes or tanks. Used when process compatibility is required, these are also applied when media exhibits high temperature or the potential to clog an instrument connection. Ideal for satisfying many challenging applications.

Key Features:

• Wide selection of diaphragm materials
• Diaphragm welded to flange extension
• Filling port in the instrument connection
• Suitable for pressure gauges, switches and transmitters

Specifications:

• Flange size: 2″ to 4″
• Flange rating: 150 to 1500 – class flanges
• Flange design according to ASME B16.5

Product Details:

Threaded Offline Non-Metallic Diaphragm Seals are designed with an upper and lower housing bolted together with a Teflon or Viton diaphragm bonded to the upper housing. This design allows for the lower housing to be removed for easy cleanout of the seal chamber while still maintaining the system fill. The Teflon and Viton diaphragms are ideal for protecting the pressure instrument from corrosive process fluid.

• Removable Lower Housing Design for Easy Cleanout
• Wide Variety of Plastic and Metallic Lower Housing Materials
• Highly Sensitive and Corrosion Resistant Diaphragm
• High Displacement Diaphragms Ideal for Mechanical Differential Pressure Gauges and Low Pressure Gauges

Construction Materials

Diaphragm (Wetted): Teflon Virgin PTFE or Viton A.
Lower Housing (Wetted): 316/316L SS, Hast C-276, Monel A400, Alloy 20, Teflon PTFE, PVC or others.
Gasket: PTFE Durlon 9600 or Viton A
Upper Housing (Non-wetted): 316/316L SS or Carbon Steel Nickel Plated
