Key Points for Selection, Installation, and Maintenance of DC Submersible Pumps

Selection criteria: Choose a pump with a rated head equal to the actual required head plus pipeline losses (10%–15%). Match the flow rate to the water demand. If the liquid contains particles or is corrosive, select materials that are wear-resistant and corrosion-proof (e.g., 316 stainless steel or engineering plastics). In solar-powered applications, prioritize BLDC motors paired with MPPT controllers.

Application areas of DC submersible pumps

Agriculture and Irrigation: Includes farmland irrigation, greenhouse water circulation, livestock drinking water supply, and other applications aimed at addressing water shortages in arid regions. Industry and Environmental Protection: Covers cooling water circulation, process water usage, wastewater treatment, and other applications involving the conveyance of corrosive or highly impure liquids.

Core features of DC submersible pumps

Wide voltage range: Common voltages include 12V, 24V, 48V, 60V, etc., making it suitable for DC power sources such as electric bicycles, solar panels, and vehicle-mounted batteries. Smart control: Supports PWM speed regulation and analog signal input for speed adjustment; customizable features include music fountains and flow rate control.

The working principle of a DC submersible pump

A DC submersible pump drives an impeller to rotate via a DC motor. Utilizing centrifugal force, the pump propels liquid (such as water) from the center of the impeller outward. As the liquid flows within the pump casing, its velocity gradually decreases and its pressure increases, eventually being discharged through the outlet.

Main application scenarios of oil pumps

Automotive applications: Oil pump (for lubricating the crankshaft, camshaft, etc.), low-pressure fuel pump (from fuel tank to fuel lines), high-pressure direct-injection fuel pump (injects fuel directly into the cylinders at 150–300 bar), and diesel high-pressure injection pump.

The core working principle of an oil pump

The moving parts (gears, vanes, plungers) and the pump housing form a sealed cavity whose volume varies periodically. When the cavity volume increases, a negative pressure is created, drawing oil fluid into the pump from the suction port.

Oil pumps are widely used in multiple fields.

Automotive industry: Used in engine lubrication systems, fuel injection systems, and more. Industrial machinery: Serves as a hydraulic power source to drive various types of mechanical equipment.
