The DeLaval duovac type replacement diaphragm is a precision-engineered pattern replacement component designed to restore reliable operation within DeLaval Duovac vacuum regulator systems. The diaphragm plays a critical role in controlling vacuum stability by responding accurately to pressure changes, helping maintain smooth and consistent milking performance.
With a 70mm diameter, the DeLaval duovac type replacement diaphragm is manufactured to fit correctly within compatible Duovac regulators when specified properly. Over time, diaphragms can become stiff, cracked, or distorted due to continuous movement, vacuum pressure, and exposure to air and moisture. Replacing a worn diaphragm helps prevent unstable vacuum levels, regulator hunting, and unnecessary stress on the milking system.
This component is supplied as a pattern part (non-OEM), offering a cost-effective alternative while still providing dependable performance for routine maintenance and repairs. Manufactured from durable, flexible material, the diaphragm is designed to respond smoothly to vacuum fluctuations, supporting consistent regulator operation throughout daily milking routines.
The DeLaval duovac type replacement diaphragm is sold individually, allowing targeted replacement without unnecessary additional parts. It is ideal for planned servicing, fault resolution, or keeping essential spares on hand to minimise downtime in busy dairy parlours.
Using a correctly sized and well-fitted diaphragm supports stable vacuum control, improved milking consistency, and long-term regulator reliability. Correct installation and regular inspection are key to maintaining optimal Duovac performance.
Always confirm compatibility by checking diameter, regulator type, and part reference before ordering.
