Brief Introduction:

The ZB series chemical process pumps are a new generation of advanced centrifugal pumps that incorporate cutting-edge technology from both domestic and international sources. They are designed to eliminate the technical shortcomings of older models like IH and CZ pumps. The ZB series includes three types: ZBG (closed impeller), ZBK (semi-open impeller), and ZBQ (fully open impeller). These pumps offer excellent anti-cavitation performance, stable sealing, smooth operation, and easy maintenance. Their high interchangeability, modular design, and use of various corrosion-resistant materials make them suitable for a wide range of industrial applications.

Parameters:
Flow Rate: Q= 2~2050 (m³/h)
Total Head: H=3~150 (m)
Pump Speed: n=1450/2900rpm
Design Temperature: T=-20~150ºC
Fluid Specific Gravity: γ≤1.85
Pump Diameter: 50~350mm

Features:
  1. Complies with ISO2858 (GB5662) and GB/T5656 (equivalent to ISO5199).
  2. Heavy-duty shaft with increased diameter improves bearing capacity by 75–160% and significantly extends bearing life.
  3. Forced internal cooling cartridge mechanical seal and large sealing chamber reduce breakdown risks.
  4. Easy adjustment method of pump rotor part ensures low pressure in the sealing chamber, reduces axial force, and guarantees stable pump operation.
  5. Multiple transforming designs expand the application range of the pump and improve reliability when pumping special fluids.
  6. High interchangeability of pump parts reduces spare parts costs for clients.

Structure:
  1. Single stage, single suction, horizontal centrifugal pump. Bracket structure for bearing parts, with the bearing housing supported by the bracket. Axial displacement of the pump rotor can be adjusted using a special bolt. Closed impeller (ZBG type), semi-open impeller (ZBK type), and fully open impeller (ZBQ type) are available.
  2. Impeller is connected to the shaft via a screw thread. An anti-vortex plate is installed at the pump inlet to enhance pump reliability.
  3. Impeller with rear blades balances the axial force at the pump suction. The gap between the rear blades of the impeller and the pump cover can be adjusted using a bolt.
  4. Back-pull type pump structure allows removal of the rotor part (impeller, shaft, shaft seal, and bearings) without dismantling the pipes during maintenance.
  5. Shaft sealing is a cartridge mechanical seal, which can also be customized as a single mechanical seal, packing seal, or secondary impeller + packing seal.

Application:

The ZB series chemical process pumps are ideal for handling clean fluids, fluids with small amounts of small particles, and corrosive liquids. They are suitable for inorganic acids, organic acids, petrochemical fluids, organic compounds, and other corrosive fluids. These pumps are widely used in:

  1. Refineries, petrochemical industries, coal mining processes, and low-temperature projects.
  2. Chemical industry, papermaking, pulp industry, and sugar production.
  3. Water treatment plants and seawater desalination projects.
  4. Power plants.
  5. Environmental protection projects.
  6. Vessels and offshore industries.
