Product Details

CWBtypeMagnetic driven vortex pumpProduct Overview

CWBtypeMagnetic driven vortex pump(abbreviated as magnetic force)Vortex pump）It applies the working principle of permanent magnet couplings tocentrifugal pumpThe new product has a reasonable design, advanced technology, full sealing, no leakage, low flow rate, high head, and corrosion resistance. Its performance has reached the advanced level of similar foreign products.
　 magnetic drive pumpBy replacing dynamic seals with static seals, the overcurrent components of the pump are completely sealed, completely solving the problems of running, emitting, and dripping that other pump mechanical seals cannot avoid.magnetic drive pumpUsing corrosion-resistant and high-strength engineering plastics, corundum ceramics, stainless steel, and other materials as manufacturing materials, it has good corrosion resistance and can protect the transported medium from pollution.

CWBtypeMagnetic driven vortex pumpProduct Features

1High head, low flow rate, with a specific speed generally less than40；
2Simple structure, small size, and light weight;
3Equipped with a self-lubricating circuit to improve the service life of sliding bearings;’
4Add a cooling circuit to promptly remove magnetic eddy current heat;
5Equipped with an axial clearance adjustment mechanism for the impeller, the clearance can be adjusted at any time to ensure the long-term normal operation of the pump.
6As the viscosity of the conveying medium increases, the efficiency of the pump sharply decreases; Therefore, the viscosity of the medium should not exceed5×10-6m2／s.
