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.
