1WZB Automatic Machinery Self-priming Peripheral Pump

The 1WZB is a solid self-priming peripheral pump that gets the job done without fuss. Built by Self Priming Pump Factory, it handles everyday water-moving tasks reliably, whether you're using it on a farm, in a workshop, or around the house.

Its automatic operation is one of the practical advantages. Once set up, the pump starts and runs with minimal attention, so you don't have to keep checking on it. The self-priming feature is another real time-saver—it clears air from the suction line on its own, so there's no need to fill the pump by hand every time you start it. That makes it useful when the water source sits a bit lower or when you need the pump to kick in quickly.

It works with clear water, lake water, or well water, as long as solid particles stay under 0.1% of the volume and no larger than 0.2 mm. Water temperature should stay below 40°C, and the pH should be between 6.5 and 8.5. Stick to those limits and the pump lasts longer.

Power options cover most common setups. The WZS version runs on three-phase 380 V (50 Hz) and tolerates voltage swings from 342 V to 418 V. The WZ version is single-phase 220 V (50 Hz) and accepts 180 V to 240 V. Both stay within their recommended head ranges for steady performance.

The peripheral design helps it build pressure efficiently, so it can move water or similar liquids without struggling. People use it for irrigation, general water supply, small industrial jobs, and home systems. Nothing flashy—just a dependable pump that does what it's supposed to.

If you need a straightforward self-priming peripheral pump, the 1WZB from Self Priming Pump Factory is worth a look.
