Dairymaster Diaphragm milk pump spacer The term “spacer” refers to a component used inside the pump assembly—most likely to maintain proper alignment or compression between the diaphragm, head, retaining rings, and valve elements. Key functions of such a spacer may include: Ensuring the diaphragm is correctly centred and positioned within the pump head assembly. Providing consistent compression or clearance to maintain a reliable seal and efficient diaphragm motion. Avoiding contact or wear between moving parts within the diaphragm assembly. MP13
