What should be the appropriate gap between the pump alignment and the motor coupling?
Thread Content
When aligning, what is an appropriate gap to leave between the pump’s drive wheel and the motor’s drive wheel?
Adjust the end-face clearance of the pump coupling using a gauge block, so that the end-face clearance between the two couplings is 4–6 mm
The claw coupling is a bit larger than the 1-3mm pin coupling; there’s no major problem with that. It’s likely that what was mentioned for floors 4-5 refers to the pin coupling! For diaphragm couplings, 0.5 mm is sufficient; I haven’t conducted any specific measurements – it’s enough as long as the diaphragm can be inserted easily! If it’s wrong, just shout at me without holding back!
Please specify what type of coupling it is: detachable, diaphragm type, elastic block type, or rigid coupling? They’re all different
What type of coupling, and what is its diameter?
