Red Water Pump Bottom Valve

Adopting integral casting of high-strength cast iron, our red water pump bottom valve features strong pressure resistance and is resistant to deformation and cracking. The surface is treated with anti-rust baking paint, preventing rust even after long-term underwater immersion and ensuring stable use in humid environments, suitable for various media such as clean water, river water, and well water.

Built-in lift check valve core; during shutdown, the valve disc closes rapidly under the combined force of water pressure and its own weight, strictly preventing backf of water to the source. The bottom features a dense reinforced screen filter that efficiently intercepts impurities such as mud, sand, aquatic plants, and stones. This prevents pump impeland pipeline blockage, reducing the likelihood of equipment failure.

Application Scenarios

Our red water pump bottom valve come in a wide range of specifications, including DN50, DN80, DN100, and DN150, compatible with various pipe diameters. Sizes are available from small household to large industrial use, meeting diverse pump flow and pipe size requirements.

1.Agricultural fields ：Used in conjunction with various agricultural centrifugal pumps and self-priming pumps for farmland irrigation, orchard watering, river water pumpinp well water extraction, farmland drainage, etc.

2.Industrial Field：Factory cooling water circulation, sewage treatment water intake, mine drainage, workshop production water supply and industrial circulating water systems.

3.Construction Engineering：Construction site temporary water supply, foundation pit drainage, fire water intake, building water supply and basement water pumping.

Installation and Maintenance

This red water pump bottom valve must be installed completely submerged below the water surface with the filter facing downwards to ensure smooth water flow and prevent air from entering the pipe.When in use, the bottom of the red water pump bottom valve should be 20-30 cm above the bottom of the water source to avoid sucking in mud, s stones, and other impurities.It is recommended to disassemble and clean the filter every 1-3 months to remove accumulated impurities and avoid clogging that affects suction efficienche condition of the sealing gasket and replace it if necessary.
