Disk and self balancing multistage pump

1The perpendicularity between the sealing surface of the balance disk and the axis shall not exceed 0.3 ‰, and its surface roughness shall not exceed. 

2.The balance plate and friction ring, as well as the balance plate and water outlet section, should be tightly fitted, and their radial contact length should not be less than 2/3 of the total length to prevent leakage from the contact surface.

3.The gap between the outer diameter of the balance disk tail sleeve and the inner diameter of the water breakthrough sleeve is 0.2~0.6mm, and the water pump for discharging mixed water can be appropriately increased.
