- Commodity name: WZBA Self-priming booster pump
Model Instruction

Application Limits
Suction lift up to 8 m
Max. Working pressure 5 bar
Liquid temperature up to +90°C
Ambient temperature up to +40°C
Voltage fluctuations should not exceed 10% of rate value

Applications Fields
• Suitable for use with clean water that does not contain abrasive particles or other similar water of liquid.
• Widely used domestic water, automatic boosting, water tower supply, well water lifting, solar hot water boosting.

Features
• Compact design,easy installation
• Pressure and flow switch control automatically
• Pump body insert of stainless sheet 304
• Shaft extension is stainless steel CS45#
• The impeller of copper alloy
• High quality mechanical seal
• Intelligent control:Pump can supply stabilized water flow by automatically running. Through the water flow and water pressure data collected by flow switch and pressure switch, electronic unit control the pump running/stop, solve the frequently starting problems under low water flow,and completely inhibit frequently starting if water flows lower than 0.3m°/h.Time delay start: 3-seconds delay on start up to prevent electric transient surge
• Dry-Run protection:Pump shut down if no water flows past pump inlet after running 6 minutes, when there is water flow past pump inlet, pump restart.
• Scale prevention:Pump will automatically run 10 seconds for scale prevention once per 3 days among outage period.
• Electronic switch: Long service lffe,and eliminate the "da da noise caused by mechanical pressure switch

Motor
• Single phase motor copper wires,ou lt-in thermal protector fully enclosed motor shell
• Continuous service S1
• IPX4 class protection
• Class B insulation
