TDV type cylindrical bag pump is a new product designed and developed by our company according to the API610 standard specifications. Suitable for conveying clean or slightly polluted low or high temperature, chemically neutral or corrosive liquids, especially suitable for operating conditions with low NPSH in the device. Performance range: Flow rate Q: 5-800m3/h; Head H: 5-800m, pressure: up to 10MPa, working temperature: -180~+180 ℃, depth under liquid can reach 3.1m.

Structural features: The TDV pump is a multi-stage, radial split type. The impeller is of single suction radial type and equipped with a single-stage housing. The first stage impeller is generally a suction impeller. The axial force is borne by the centripetal thrust ball bearing, which relies on lubricating oil lubrication. In the case of a large pressure difference, the axial force is balanced by the balance drum device. The hydraulic model of high-efficiency and energy-saving pump is adopted for the hydraulic flow part. When the underwater insertion length exceeds 2 meters, a connecting shaft structure is adopted. The pump body of this pump is immersed in liquid, so it has the characteristic of no leakage to the outside. From the direction of the drive end, the pump rotates counterclockwise.
