Issues related to shielded pumps in our factory
Thread Content
Shielded pumps have axial movement. When a shielded pump is in operation, does the shaft move towards the impeller or towards the rear end? Can this direction of movement be changed, and if so, how?
Different factories have different requirements for clearance for movement. You can’t change it; ask the manufacturer for the axial clearance requirements for different models.
How are the shielded pumps from Hefei Xinhu? Has anyone used them?
In principle, the ideal situation is to have no forward movement (of the impeller) nor backward movement (at the tail end)； It can be adjusted to move forward or backward through axial force. For example, with vertical pumps, manufacturers generally tend to adjust the axial force upward in order to counteract the weight of the rotor. It is difficult for end-users to accurately adjust this axial force after the pump has been manufactured; they can only rely on experience. More or less
We have 55 units installed, but they haven’t been put into use yet
If you use a high-quality magnetic pump, you might not choose a canned motor pump. 13514114845
Thrust movement is a dynamic process; the clearance is generally 0.2–0.3 mm, ensuring no friction between the moving and stationary components!
