Product Introduction

Optimized Fluid Lifting with 2 1/2" SV Type Swab Cups

The 2 1/2" SV style swab cup is a rubber and metal-core component for light to medium fluid lifting during well servicing. This listing brings together material options for selecting a replacement cup against the actual well fluid, temperature and existing assembly. Confirm the SV profile and mounting dimensions against a drawing or sample before ordering.

NBR, HNBR and FKM options require compound-specific selection. Provide the fluid composition, additives, temperature range, solids content and exposure duration so the proposed material can be reviewed. Cup service life depends on tubing condition, fit, wear and operating practice.

Technical Specifications

Material Selection Guide

• Nitrile (NBR): An option for oil-service enquiries. Confirm compatibility with the actual fluid, additives and operating temperature.

• HNBR: Review where the service requires an alternative to NBR. Temperature and chemical suitability depend on the specific compound and exposure conditions.

• FKM: Consider for selected heat and chemical exposure requirements after compound-specific review; it is not suitable for every well fluid.

Key Features & Advantages

1. Abrasive Service Selection
For wells containing sand or suspended solids, provide concentration, particle size and worn cup photographs. These details help assess lip wear and replacement requirements. Inspect the cup and tubing contact surface before reuse.

2. Flexible SV Sealing Profile
The flexible sealing lip contacts the tubing wall during fluid lifting. Actual recovery depends on the selected cup dimensions, lip condition, tubing inside diameter and assembly configuration.

3. Tubing and Deposit Checks
Tubing restrictions, scale and deposits can cut or deform the lip. Review the tubing condition and follow the operating team's tool-running procedure; flexibility does not guarantee passage without damage.

4. Compound-Specific Material Review
Identify oil-based mud additives, completion fluids, acid treatments and temperature excursions in the enquiry. Sour-service use requires review of the specific elastomer and metal components under the stated H2S conditions; a material family name alone does not establish qualification.

FAQ

Q: Why choose the SV style over an MV or V type swab cup?
A: Compare the actual lip profile, mounting dimensions, material and assembly duty with the existing equipment. SV, MV and V style names identify profiles rather than a universal load rating or a guaranteed service-life difference.

Q: Will this 2 1/2" cup fit all 2.5" tubing?
A: No universal fit is implied by the nominal size. Supply tubing inside diameter, cup outside diameter, bore, seating dimensions and retention details to confirm the required assembly.

Q: What is the maximum pressure this swab cup can handle?
A: This listing does not establish a pressure rating. Confirm the rated swab assembly and operating limits with the equipment supplier and operating team; hardness and nominal cup size alone are insufficient.

Q: How do I increase the service life of my swab cups?
A: Match the compound to the fluid and temperature, inspect the tubing contact surface, and check the cup for cuts, swelling or permanent deformation. Follow the equipment operating procedure and replace worn components; service life remains condition-dependent.
