Vertical pump coupling
Thread Content
For vertical constant-pressure fire pumps, should clamped rigid couplings or diaphragm couplings be used?
Generally, a shell-type rigid coupling is commonly used for the couplings of vertical pressure-stabilizing fire pumps. Because the shell-type rigid coupling has advantages such as a simple structure, long service life, and high rotational accuracy, and it is suitable for high-torque and high-speed transmission. Diaphragm couplings are suitable for transmission systems with low power, low torque, and high precision; for driving high-power fire pumps, they may not be as stable and reliable as rigid coupling types with shells. .
