LZA (OH1) single stage cantilever pump

>Pump body: The pump body adopts a volute structure design, and the pump body outlet ≥ DN80 adopts a double volute hydraulic design, which greatly balances the radial force.

>The suspension components (bearing box, bearings, shaft, gland, pump cover, etc.) adopt an overall pull-out design, which enables inspection and maintenance of the pump without moving the inlet and outlet pipelines.

> Shaft: The shaft is a bare shaft structure, and the stiffness index of the pump shaft meets the requirements of API610 11* Appendix K. At the same time, the impeller nut anti-reverse structure is adopted to meet the needs of on-site working conditions and improve the safety and stability of the equipment.

> Axial force balance: Wear-resistant rings are designed on both sides of the impeller, and a balance hole is opened on the inside to make the pressure on both sides of the impeller self-balance, and the push bearing only bears a lower load.

> Bearings and lubrication: The front bearing (the bearing close to the pump head) uses deep groove ball bearings, which only bear radial force.The rear bearing (the bearing close to the driving end) uses a pair of angular contact ball bearings (73 series) or a pair of tapered roller bearings (31 series): the bearings adopt an oil ring lubrication structure, and a bearing isolate type seal can be selected according to user needs or labyrinth seal.

> Mechanical seal: The seal cavity size complies with API682 4th “Centrifugal Pump and Rotary Pump Shaft Seal System”, and various forms of sealing, flushing, and cooling solutions can be configured.
