Description

Biasi BI1011103 Central Heating (CH) Diaphragm

This Is The Central Heating Diaphragm/Membrane.

This Biasi Diaphragms is also known as a membrane, it is a part that normally sits within the diverter valve or hydraulic section of the boiler. The main purpose of this diaphragm is to move a pin that then operates a micro switch which in turn sends a signal to the pcb.

The signal is normally to indicate the pump is running or there is a demand for hot water. The diaphragm BI1011103 is sometimes referred to as the pump proving ? flow diaphragm or the domestic hot water DHW diaphragm.

Most Engineers place a small amount of Silicone Grease around the edge of the Biasi Diaphragm to ensure there is a perfect seal ensuring there are no leaks once the diaphragm is fitted.

If you would like to purchase the silicone grease we may have displayed below for you to purchase if required.
