Jinxin ZA and ZE are horizontal, single-stage process pumps with axial suction and radial discharge. ZA uses foot support, while ZE uses centerline support for duties requiring a different casing support arrangement.
The range uses a closed impeller and replaceable wear rings. Packing, single mechanical seals and double mechanical seals are catalog options, with flushing or cooling arrangements selected for the pumped liquid. A seal choice therefore needs the process composition and operating temperature rather than the series name alone.
The published family envelope extends to 2,600 m³/h and 250 m head across DN25–400 sizes. These maxima describe different selections and must not be combined into a single duty point. ZA and ZE also have different published casing pressure limits, so support style and pressure rating should be agreed together before a detailed curve is chosen.
SELECTION NOTES
Specify the operating duty
Provide the required flow and differential head, inlet pressure, temperature, fluid chemistry and density. Confirm ZA or ZE support, material schedule, seal plan and the selected performance curve.
Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
