What Is the Best Submersible Well Pump for a 135QJP Installation?

This FAQ explains how to assess the 135QJP Peep Well Submersible Pump for a well installation, including power, water quality, immersion, positioning, cable selection, overload protection, and operating flow. The right choice depends on matching the pump to the well, water conditions, and required output.

The answer to “what is the best submersible well pump” depends on the well and the operating conditions. The 135QJP Peep Well Submersible Pump is intended for a vertical, fully immersed installation with clean water, a compatible cable, and external overload protection. Use the questions below to check whether its operating requirements fit the project.

Questions buyers ask about the 135QJP

What power supply does the 135QJP require?

The pump uses a three-phase AC 380 V power supply with a tolerance of plus or minus 5 percent and a frequency of 50 Hz with a tolerance of plus or minus 1 percent. The cable must be matched to the pump requirements, and the installation must include an external overload protection device.

Before ordering, send the available power supply details and cable length to the supplier so the electrical arrangement can be checked against the selected pump configuration.

What water conditions suit this submersible well pump?

The water temperature must not exceed 20 °C. Solid impurities must not exceed 0.01 percent by mass. The pH range is 6.5 to 8.5, hydrogen sulfide must not exceed 1.5 mg/L, and chloride ions must not exceed 400 mg/L.

A buyer planning to use the pump in a well should compare these limits with a current water analysis. This is especially important where the well may contain suspended solids, elevated chloride, or hydrogen sulfide.

How should the pump be positioned in the well?

The pump must be completely immersed and installed vertically. The diving depth must not exceed 70 m, and the distance from the bottom of the pump to the bottom of the well must be at least 3 m. The well must be vertical, and the pump cannot be used horizontally.

Picture the installation during service: the pump is lowered into a straight well, remains surrounded by water, and stays clear of the bottom. Measure the well depth and check the available clearance before selecting the installation arrangement.

What should be checked before starting the pump?

The motor cavity must be filled with clean water before use, followed by tightening the water injection and air release bolts. The pump must be completely immersed before operation. A no-load test without water is prohibited.

The well flow must support the pump's water output and continuous operation. The water output should be controlled at 0.7 to 1.2 times the rated flow. Confirm the well flow, power supply, cable arrangement, overload protection, immersion depth, and bottom clearance before commissioning.
