Self-Priming Brushless DC Surface Pump

This brushless DC surface-pump family combines the yellow self-priming pump and carrying-frame designs shown in the supplier catalogue. Choose the exact model for the required flow, total head and connection size.

Solar DC QD: 14 models

QD models are listed for solar systems with an MPPT or suitable solar controller. The catalogue marks the controller as optional. Check the selected model's working voltage range and compatible solar supply before ordering.

Battery DC ZM: 6 models

ZM models are listed for battery systems with a suitable battery controller. The catalogue describes on/off control, five speed settings and remote control. Use the ZM model's own voltage, power, flow, head and connection specifications.

Choose the electrical configuration and pump duty together

QD and ZM configurations have different electrical and controller requirements; do not assume that their power components are interchangeable. Confirm which controller, solar panels, battery and accessories are included in the quoted supply. Prime the pump as required, keep the suction line airtight and support the water lines independently. The maximum liquid temperature is 35°C.

The performance chart below applies only to the 14 Solar DC QD models. It does not establish a performance curve for the Battery DC ZM models. Maximum flow and maximum head are separate limits; select for the actual total head, including pipe losses.

Flow and head performance

Read the curve at your required flow and total head. Maximum flow and maximum head are separate limits, not one operating point.
