Booster Pump Head Oversold, Constant Pressure Pump Starting Hundreds of Times a Day? NL-BPS-6 Variable-Speed Pump Test Bench, Six Stations (pump test bench)

Household booster pumps that claim fifteen meters of head on the box yet leave the upstairs shower dribbling; variable-speed constant-pressure pumps that start and stop every time a tap opens and closes, hundreds of cycles a day, until shower temperature swings and the pump grows loud and can no longer hold pressure within six months. The rated H-Q curve was measured on clean water at rated voltage at a single point. Constant-pressure accuracy, start-stop frequency, pressure band width and long-term decay under real duty never see a bench before shipment, and the after-sales answer is swapping the pump.

What the NL-BPS-6 variable-speed pump test bench measures

• Six stations in parallel with inverter and pressure closed-loop control, sweeping the measured H-Q curve point by point against the rated curve, exposing head overselling (the household branch of our pump test bench)
• Constant-pressure accuracy: tap open, close and half-open sequences, logging the outlet pressure band and recovery time (the constant-pressure branch of a pump performance test)
• Start-stop frequency and life: tens of thousands of cycles on a real use rhythm, tracking inrush current, response time and noise
• Dry-run and low-flow protection: timed line drain-down, recording trip and reset behaviour
• Temperature rise and efficiency logged together: motor heating, input power and useful output captured in continuous duty
• Barcode and batch binding, with raw data exported per unit for incoming acceptance and supplier comparison

Applicable standards

GB/T 3216 (rotodynamic pumps – hydraulic performance acceptance tests – grades 1, 2 and 3), GB/T 5657 (centrifugal pumps – technical conditions), IEC 60335-2-41 (pumps for liquids – particular requirements), GB 4706.1 (household appliances – general safety) and GB/T 2828 sampling; criteria can follow the customer’s standard and the supply system requirements.

Stations and throughput

Six stations running 24/7 turn a glance at a gauge and a listen into curves, cycle counts and trends, with constant-pressure accuracy and start-stop decay rechecked round by round — so incoming pumps and end-of-line assemblies can both be sampled batch by batch, stopping head overselling and cycling failures before shipment.
