Openwell Submersible Pump

Openwell Submersible Pumps are high-efficiency centrifugal pumps designed to operate fully submerged in open wells, tanks, and reservoirs. They provide reliable water transfer for agricultural, domestic, and industrial applications with minimal maintenance and excellent cooling performance.

Product Overview

An Openwell Submersible Pump is a centrifugal pump designed to operate while fully submerged in water inside open wells, tanks, reservoirs, and sumps. Unlike borewell pumps, these pumps are installed horizontally or vertically in open water sources where the water level remains relatively stable.

The pump and motor are integrated into a single compact unit, which eliminates the need for priming and ensures efficient water transfer. Since the pump operates underwater, it benefits from natural cooling provided by the surrounding liquid, resulting in longer motor life and improved performance.

Openwell submersible pumps are widely used in agriculture, domestic water supply, irrigation systems, construction sites, and industrial water transfer applications. Their rugged design allows them to handle continuous operation with high efficiency and low maintenance requirements.

These pumps are particularly suitable for situations where a large quantity of water needs to be lifted from shallow wells or water storage structures.

Technical Specifications

The Openwell Submersible Pump is a centrifugal type pump designed for horizontal or vertical submerged installation in open wells, tanks, and reservoirs. The pump is typically available in a power range from 0.5 HP to 15 HP, depending on the model and application requirements. These pumps can deliver a flow rate ranging from approximately 50 LPM to 1000 LPM, with larger models capable of handling higher capacities. The maximum head generally ranges from 5 meters to 60 meters, depending on the pump design and motor capacity. The pump operates at a speed of around 2800 to 2900 RPM and is available in single-phase (220–240 V) as well as three-phase (380–415 V) electrical configurations with a 50 Hz frequency. The motor is designed for continuous duty (S1) and typically features a protection class of IP58, ensuring safe operation while fully submerged in water. The maximum liquid temperature handled by the pump is usually up to 33°C. Openwell submersible pumps are available with discharge outlet sizes ranging from 25 mm to 100 mm, depending on the pump model and flow capacity. The pumps are designed to operate with liquids having a pH value between 6.5 and 8.5 and a specific gravity up to 1.004.
