ZX horizontal self priming centrifugal pump

A horizontal self-priming centrifugal pump designed for reliable transfer of clear water, seawater, acidic or alkaline chemical solutions and light slurries. The ZX series combines robust construction with strong self-priming capability to simplify piping and reduce installation time.

Key features:

• Self-priming performance: suction lift up to 4–5 m; pump will re-prime when liquid remains in the casing, eliminating the need for a separate bottom check valve in many installations.
• Construction options: cast iron (HT200) or corrosion-resistant stainless steel (SUS304, SUS316, SUS316L) to suit different liquids and environments.
• Drive options: compatible with standard electric motors or explosion-proof motors for hazardous locations.
• Compact, modular design for easy installation, operation and maintenance.
• Smooth, efficient operation with long service life and low maintenance requirements.

Typical specifications (model-dependent):

• Flow rate: 3 – 600 m3/h
• Head: 12 – 80 m
• Motor power: 0.75 kW – 132 kW
• Discharge diameter (caliber): 25 – 300 mm
• Maximum suction lift: 4–5 m

Common applications:

• Agricultural spraying and irrigation (farms, nurseries, orchards, tea gardens)
• Municipal and environmental systems, construction dewatering
• Fire protection and cooling systems
• Chemical processing, electroplating, printing & dyeing, brewing
• Pharmaceutical production, papermaking and general industrial fluid handling

Selection and installation notes:

• Choose pump material based on fluid corrosivity and solids content (SUS316/316L for more aggressive media).
• Verify motor type (standard vs. Ex-proof) against site safety requirements.
• Ensure the pump casing retains some liquid before start-up for reliable self-priming performance.

The ZX horizontal self-priming centrifugal pump is suitable where a compact, easy-to-service pump with reliable suction capability is required across agricultural and industrial applications.
