SE20 Diaphragm pack - EL60 / 80 / 100 / 120W / 150W / 200W

Kit contains : 2x EL diaphragms, plus their plastic surrounding frame and 4x spacer strips to help with reassembly.

If your pump is more than 3 years old it might be wise to consider a Service Kit instead.
For servicing BOTH heads of a twin head pump you need 2x of these kits.
For EL120S/EL150S (single head) and EL250W (twin head) you need a SE25 diaphragm pack (see below).

This pack fits the following pumps :

SINGLE HEAD
EL60 / EL60C (but not EL60n, which uses the SE60D pack listed below)
EL80-15
EL80-17
EL100 / EL100C

TWIN HEAD (two packs recommended)
EL120W
EL150W / EL150WC
EL200W / EL200WC
EL300W / EL300WC

This will NOT fit the EL60N (see below for SE60D pack)
