Submersible Pumps
ACCA submersible pumps combine a multistage pump end with a submerged electric motor for deep wells, municipal and industrial water, irrigation and other installations where the motor and pump operate below the water level.
Submersible Pump Engineering Range
Flow
Standard submersible selections cover approximately 80–1,600 GPM. For special installations, adapted vertical pump hydraulics can extend capacity to approximately 5,780 GPM.
Head
Multistage configurations can develop approximately 1,500 ft of head, with stage count established from the required duty and selected hydraulic.
Pump-End Sizes
Available pump ends span approximately 5–14 inches, providing multiple hydraulic families for different well diameters and operating points.
Speed
Typical motor arrangements include approximately 1,760 or 3,460 RPM depending on pump size, hydraulic selection and motor configuration.
Published range limits describe available equipment capability. Final performance is confirmed from the selected pump curve and application conditions.
Configurations
Vertical Deep-Well
The conventional arrangement places the multistage pump end and submersible motor vertically in the well below the pumping water level.
Angled Installation
Selected configurations can operate at an angle when site geometry does not permit a conventional vertical setting.
Horizontal / In-Line
Special submersible arrangements can be installed horizontally inside a line when motor cooling, hydraulic conditions and mechanical support are properly engineered.
Canned Booster
A submersible pump can be installed inside an engineered can for booster service where no wet pit is available or direct connection to a water line is required.
Construction & Materials
A common water-service construction uses Class 30 cast-iron bowls, Bronze 844 impellers and 416 stainless-steel shafting. Materials can be changed when water chemistry, corrosion, abrasion or project specifications require a different construction. A suction strainer is recommended where practical to reduce the risk of larger solids entering the pump.
The submersible motor mounts directly to the pump end through a motor bracket. The motor must accommodate the pump’s axial thrust, and the underwater power cable must be selected for continuous submerged service.
Applications
Municipal Wells
Groundwater production and municipal water supply where a compact submerged installation is preferred.
Irrigation
Agricultural wells and water-supply systems selected around seasonal water levels and system pressure.
Industrial Water
Plant water, groundwater and other clean-water duties where well geometry and electrical service favor a submersible arrangement.
Booster Service
Canned configurations can provide pressure boosting without constructing a conventional open wet pit.
Technical Selection Guidance
Provide required GPM and TDH, well diameter, static and pumping water levels, drawdown, setting depth, liquid temperature and chemistry, motor voltage/phase/frequency, cable length and starting method. Selection must verify motor cooling, axial thrust, NPSH/submergence and operation within the pump curve.
Soft starters or other appropriate motor protection should monitor electrical conditions and protect the submerged motor from abnormal current or operating conditions. Final controls depend on motor and system requirements.
