Reference Confirmation Keep all letters and suffixes exactly as recorded on the sample, service record or drawing.
Application Scope Selected Grundfos sewage and wastewater pump replacement work, subject to configuration matching.

Component Layout Compare the metal-bodied components, mating rings and secondary-seal profiles visible in the product photographs.
Material Specification Confirm the complete face pair, elastomers and metal specification. A single material abbreviation is not a complete replacement specification.
Service Duty State the pumped liquid, solids conditions, temperature, pressure and speed for selection.
Scope of Supply Clarify whether the enquiry covers an individual seal, selected ring components or a complete service set; photographs do not define the shipment quantity.
Operating Limits Confirm limits for the quoted design, materials and actual installation; no common numerical rating is assumed across the listed variants.

Product Description

The GLF-SRL-SA replacement seal range is listed for selected Grundfos sewage and wastewater pump applications, with 32L, 38L, 50L and 65L references. Keep the complete reference and suffix when requesting a replacement, and provide the pump identity alongside it.

This product listing shows several metal-bodied seal components and mating rings. Before ordering, specify the assembly and sealing position required, and whether the quotation should include a single replacement or a broader set of service parts. Similar ring diameters or a shared series name are not sufficient to establish an interchangeable assembly.

Start with the Grundfos replacement seal selection guide and compare the assembly with the mechanical seal identification guide. The Grundfos mechanical seal range provides other references, which still require their own dimensional and application checks.

Grundfos names are used to identify compatible pump applications only. Hong Teng supplies this aftermarket replacement independently; it is not represented as an original Grundfos part.

Application

Suitable Replacement Enquiries

  • Replacement enquiries for selected Grundfos sewage, drainage and wastewater pumps with a matching GLF-SRL-SA arrangement.
  • Planned maintenance where the full variant, sealing position and required ring or assembly set can be confirmed.

How to Confirm the Correct Configuration

  1. Copy the full reference, including 32L, 38L, 50L or 65L and any further suffix shown in service records.
  2. Photograph the seal parts together and separately; identify their installation position in the pump.
  3. Provide mating diameters, ring thicknesses, installed length, liquid conditions and the requested supply scope.

Before ordering: Send the pump details and seal photographs to Hong Teng for confirmation of the required configuration and supply scope.

Product Questions

Do the L suffixes by themselves identify the installation position?

Do not assign a position from an abbreviation alone. Confirm the full reference with the pump drawing and the actual assembly.

Are all parts shown in every photograph included in one set?

Not automatically. Confirm the component list, quantities and exact variant in the quotation.

Can one material abbreviation confirm the replacement specification?

No. The specification needs the relevant face pairing, secondary seals and metal parts, together with dimensions and service conditions.
