Zb Strong Self Priming Pump With Vacuum Suction Device

A robust self-priming centrifugal pump designed for applications that require rapid, reliable priming without external priming equipment. The integrated vacuum suction device enables automatic priming from a suction lift up to 9 m and minimizes cavitation by keeping the space between the liquid level and the impeller under vacuum. The unit can be driven by an electric motor and paired with an optional automatic control cabinet for fully automatic start/stop and protection functions.

Key features

• Self-priming performance up to 9 m suction lift — no external priming pump, foot valve or pre-filling required
• Short priming times: 6–90 seconds depending on flow and conditions
• Wide flow capacity: approximately 6.3 to 1500 m³/h
• Vacuum suction device reduces cavitation and improves hydraulic efficiency and priming altitude
• Clutch mechanism allows manual or automatic engagement/disengagement of the vacuum device to extend service life and save energy
• Simple ground-mounted installation — pump operates once the suction line is inserted into the water
• Compatible with an automatic control cabinet for unattended, fully automatic operation

Benefits

• Faster startup and reduced downtime compared with pumps that require external priming
• Lower maintenance on impeller and hydraulic components thanks to reduced cavitation
• Flexibility for industrial, municipal and agricultural installations where suction lift or intermittent operation is required

Typical applications

• Water supply and transfer
• Irrigation and agricultural pumping
• Dewatering and drainage
• Industrial process and recirculation pumping

Notes

• Select motor size, coupling and control panel options according to site electrical standards and required duty cycle. Model example: ZB150-125-315.
