Buyer summary: MIL-00001 lists two 43 mm and two 17.4 mm silicone membranes. PUL-00006 lists two large and two small silicone membranes with an LE20 catalogue fit reference. PUL-00007 lists three large silicone membranes and two circular seals with an LE30 catalogue fit reference. Keep each kit description with its SKU; the references do not establish a confirmed fit for every pulsator revision.
A replacement enquiry needs both the parts required and enough detail to identify the installed pulsator. This guide compares three existing membrane-kit records. It supports parts procurement, rather than a maintenance procedure, service interval or guarantee of restored performance.
Separate membrane-only sets from membrane-and-seal sets
MIL-00001 and PUL-00006 each list two large and two small membranes. Only MIL-00001 supplies the two diameter values in the reviewed records. PUL-00007 instead lists three large membranes and two circular seals. Equal piece counts or a similar photograph do not identify the same set; list the required parts and SKU together.
Keep dimensions with their source SKU
The 43 mm and 17.4 mm diameters belong to MIL-00001. They must not be copied into the PUL-00006 or PUL-00007 order. For those kits, request model-specific dimensions. For any proposed match, provide labelled photographs and measurements of the existing parts, including profiles and openings where relevant. Diameter alone does not establish an interchangeable part.
Treat LE20 and LE30 as catalogue references
PUL-00006 carries the LE20 fit reference and PUL-00007 the LE30 reference. These are catalogue identifiers for an enquiry, not claims of original-brand manufacture, authorization or verified compatibility with every revision. Provide the existing pulsator label and revision, then ask for the exact proposed kit to be checked. The membrane-only set MIL-00001 has no named model fit reference in this comparison.

Quotation checklist
- Requested ERRASONVET SKU and number of kits; distinguish kit quantity from individual membrane quantity.
- Existing pulsator label, model or revision and clear photographs of the removed parts.
- A labelled list of required membranes and seals, with measured dimensions, openings and profiles.
- Confirmation of the exact contents, material and dimensions supplied for the selected kit.
- Any documented service-condition or material requirements from your equipment instructions; ask for a confirmed match rather than inferring it from silicone alone.
- Destination country, packaging requirements and any additional parts required. Ask for unlisted items separately.
Frequently asked purchasing questions
Do all three kits contain four membranes?
No. MIL-00001 and PUL-00006 each list two large and two small membranes. PUL-00007 lists three large membranes and two circular seals.
Can the 43 mm and 17.4 mm diameters be used for the LE20-reference kit?
Those diameters are listed only for MIL-00001 in these records. PUL-00006 needs its own dimensional confirmation; the piece-count similarity does not establish a match.
Does an LE30 catalogue reference prove original-brand supply?
No. PUL-00007 has an LE30 catalogue fit reference. This is not evidence of original-brand manufacture or authorization, and a revision-specific fit still needs confirmation.
Is a pulsator included with the membrane set?
MIL-00001 is a membrane set; its installation photograph does not include the pulsator in the supplied set. Confirm the itemised contents for every selected SKU.
Does this comparison establish a replacement interval or installation procedure?
No. These product records establish the listed parts and procurement fields. Obtain the applicable equipment instructions and model-specific service requirements before maintenance.
