Product Features
■ Designed according to API610 standards, with high reliability and stability, and a long service life
■ Unique flow channel that eliminates secondary backflow loss, achieving small flow and high efficiency
■ Cone-shaped shaft seal cavity with good selfcleaning effect, simplifying the auxiliary system of the mechanical seal
■ Large volume oil pool and large return oil channel for long bearing life
■ The pump shaft uses a heavyduty thick shaft, which has good rigidity and impact resistance, capable of withstanding certain heavy loads
■ High degree of generalization and standardization of the pump with strong interchangeability
■ Various corrosion-resistant materials designed for different working conditions
Product Structure
■ Single-stage single-suction cantilever chemical centrifugal pump
■ Features a foot support with radial sectional structure
■ Bearing components are an adjustable rotor structure with bearing boxes
■ The pump body has a side discharge annular volute
■ Sealing method is mechanical seal, direct drive (claw couplings/membrane couplings)
The schematic diagram of the pump structure is as follows.
