CZA (OH1), CZE (OH2) series process pump

CZA and CZE series are magnetic drive single-stage single-suction horizontal centrifugal pumps. The water conservancy model is the same, the difference lies in the way of the pump body support and the design pressure of the pump casing. Among them, CZA is the foot support (standard type code OH1); CZE is the center support (standard type code OH2). The pump outlet pipe diameter DN80 and above is designed with double volute casing to balance the radial force. The axial force is balanced by the balance chamber. The axial force of residual and abnormal working conditions is carried by the thrust plate in both directions. Sliding bearings usually use SSiC material. SSiC bearings (including thrust discs) are designed for spherical seats. The driving end of the pump is rolling bearing and oil lubricated. The bearing box can be designed for natural cooling or water cooling. The bearing box can be installed with a dry gas mechanical seal to form a secondary seal. Diaphragm lengthened coupling is used for motor and pump. Small-size pumps (22kw and below) can be designed as direct-connected motors. The pump steering is seen clockwise from the drive end.
