Dry Gas Seal Quote: Required Data and Selection Information

Quick Answer: A dry gas seal quote requires the compressor model, shaft diameter, seal chamber dimensions, gas composition, pressure, temperature, rotor speed, and an existing drawing or tag number. CORASEALS supplies dry gas seals and replacement parts for centrifugal compressors and gas-handling equipment. Send the requested data below to receive a dry gas seal quotation.

CORASEALS supplies dry gas seals and replacement parts as part of a wider industrial seal range. That range also includes mechanical seals, gaskets, O-rings, hydraulic seals, and compression packing.

This dry gas seal quote page covers the data needed for selection, material review, and quotation. Do not rely on a generic shaft size alone. Dry gas seal designs vary by arrangement, seal face material, secondary seal material, and gas conditions.

What a Dry Gas Seal Quote Must Include

Send the following application data for a dry gas seal quote:

Compressor or equipment make and model
Shaft diameter in millimeters or inches
Seal chamber bore and available axial space
Existing seal drawing, part number, or tag number
Process gas composition and possible contaminants
Operating pressure and discharge pressure
Seal gas supply pressure and flow rate
Operating temperature range
Rotor speed in rpm and rotation direction
Required quantity and target delivery location

If the existing seal drawing is available, include the drawing with the inquiry. The drawing helps confirm face geometry, seat design, spring arrangement, and connection positions.

Why Application Data Matters for Dry Gas Seals

Dry gas seals operate with a thin gas film between the rotating face and the stationary face. The film stability depends on pressure, speed, gas density, and seal face geometry. The same shaft size can require different seal assemblies depending on the compressor model.

Process gas composition also affects material selection. Hydrogen, CO2, H2S, moisture, and condensate can influence face material and secondary seal selection. CORASEALS reviews the gas composition before a dry gas seal quote is issued.

Dry Gas Seal Arrangements

Common dry gas seal arrangements include single, double, and tandem configurations. The arrangement depends on process gas pressure, leakage limits, venting requirements, and the seal gas panel design. A dry gas seal quote cannot be confirmed from a generic size only.

Dry Gas Seal Materials

Common dry gas seal face materials include silicon carbide, tungsten carbide, and carbon graphite. Secondary seal materials may include FKM, FFKM, NBR, PTFE, and metal bellows. Metal parts may be supplied in stainless steel or higher alloy grades depending on gas composition and temperature.

CORASEALS can quote dry gas seals and spare parts based on the original material specification. If the original material grade is unknown, send the gas composition and operating temperature so the correct material can be reviewed.

Dry Gas Seal Quote Process at CORASEALS

After the data is received, CORASEALS reviews the seal type, dimensions, arrangement, and materials. If the requested seal can be cross-referenced from the drawing and dimensions, the quotation is prepared from the supplied details. If the drawing is incomplete, CORASEALS may ask for additional dimensions or connection details before pricing.

Dry Gas Seal Quote FAQ

Q: What information is required for a dry gas seal quote?

A: Send the compressor model, shaft diameter, seal chamber dimensions, gas composition, operating pressure, temperature, speed, rotation direction, existing drawing, and required quantity.

Q: Can CORASEALS quote a dry gas seal from a tag number only?

A: A tag number is useful, but a tag number is not always enough. Include the existing drawing or main dimensions. The drawing helps confirm the face geometry, arrangement, and connection layout.

Q: Does CORASEALS supply dry gas seals for centrifugal compressors?

A: Yes. CORASEALS can supply dry gas seals and replacement parts for centrifugal compressors and other gas-handling equipment. Send the compressor model and seal drawing with the inquiry.

Q: Can you quote replacement dry gas seal faces?

A: Yes. Send the existing seal drawing, face material, seat material, and any damage photos if available. The drawing and material details help confirm the correct face design and material grade.

Q: How do I know if a single, double, or tandem dry gas seal is required?

A: The arrangement is normally selected from the compressor design, seal gas panel, and process gas conditions. Send the existing seal drawing or seal tag data. CORASEALS will review the arrangement with the application data before quoting.
