Corrosion-Resistant Water Disinfection Dosing Pump

The Corrosion-Resistant Water Disinfection Dosing Pump is a water-powered proportional dosing unit designed for controlled injection of compatible disinfectants, acidic additives and liquid treatment concentrates into poultry and livestock drinking water systems.

The reference configuration uses a PVDF housing with high chemical resistance and an external injection arrangement. This design is particularly suitable for demanding water treatment conditions involving concentrated acidic or aggressive additives where material compatibility is essential.

Installed directly into the water supply network, the pump uses water pressure as its driving force. It draws concentrated treatment solution from an external container, meters it according to the selected dosing ratio and mixes it with the water flowing through the system.

The equipment is suitable for commercial poultry farms, pig farms, cattle farms, rabbit farms and centralized livestock water treatment stations. It can also be integrated into livestock equipment projects, pig farm construction and steel structure building water supply systems.

• Corrosion-Resistant Construction: PVDF housing provides high chemical resistance for selected aggressive treatment concentrates.
• Water-Powered Operation: Uses water pressure as the operating force and does not require electricity for proportional dosing.
• Flow-Proportional Dosing: Injection quantity changes automatically according to the amount of water flowing through the pump.
• Adjustable Dosing Ratio: Allows operators to set the required injection concentration within the operating range of the selected configuration.
• External Injection: Helps protect the hydraulic motor from direct contact with highly concentrated treatment solution.
• Acid-Compatible Configuration: The reference version includes sealing components intended for acidic additives.
• Automatic Chemical Suction: Draws concentrated treatment solution from a separate chemical container during water flow.
• Consistent Treatment: Proportional operation helps maintain a stable additive-to-water ratio as livestock water consumption changes.
• Flexible Installation: Suitable for direct inline installation or integration into a bypass assembly.
• Commercial Farm Use: Suitable for poultry, pig, cattle and other intensive livestock production systems.
• Compact System Integration: Can be combined with water filters, pressure regulators, valves, tanks and water distribution equipment.
• Customizable Configuration: Supporting components can be selected according to project requirements.

• Hydraulic Motor: Uses incoming water pressure and flow to drive the dosing mechanism.
• PVDF Housing: Provides enhanced resistance to selected corrosive treatment chemicals.
• Dosing Assembly: Draws and meters concentrated solution into the water stream.
• Adjustment Mechanism: Allows the required injection percentage to be selected.
• External Injection Kit: Introduces concentrated additive outside the main hydraulic motor section.
• Acid-Compatible Seals: Used in the reference configuration for acidic additive applications.
• Water Inlet and Outlet: Connect the pump directly to the farm water network.
• Chemical Suction Hose: Connects the dosing unit to the stock-solution container.
• Suction Filter or Foot Valve: Helps reduce entry of particles from the chemical container.
• Mounting Support: Provides stable installation on a wall or treatment station.
• Optional Water Filter: Helps protect the hydraulic mechanism from suspended particles.
• Optional Bypass Valves: Allow isolation of the dosing pump for inspection and maintenance.

The final component arrangement should be confirmed according to water quality, treatment chemical, pipe size, farm capacity and required dosing program.

The dosing pump is installed in the livestock drinking water supply line. As water enters the pump, the hydraulic motor is activated by water pressure. The resulting mechanical movement operates the dosing piston without requiring an electric motor.

The dosing section draws concentrated disinfectant or compatible treatment solution through the suction hose from an external container. A measured amount of concentrate is injected according to the selected proportional setting.

Because the dosing action is linked directly to water flow, the injected quantity increases when water consumption rises and decreases when water consumption falls. This is useful in livestock production where drinking-water demand varies throughout the day and during different production stages.

In the external injection configuration, concentrated chemical solution enters the water downstream of the main hydraulic motor. This arrangement reduces direct contact between aggressive concentrate and the motor section and supports demanding water disinfection and acidification applications.

Note: The numerical specifications above are based on the referenced D25RE2 IE PVDF configuration. Final parameters should be confirmed according to the selected pump model and actual project requirements.

Chemical Compatibility: The actual disinfectant, acidifier and concentrate must be checked for compatibility with the housing, seals and dosing components before use.

SHEWUYOU can coordinate the dosing pump with livestock equipment, water supply pipelines, filtration assemblies and drinking-water distribution systems for new construction and farm renovation projects.

The dosing pump should be installed in the direction of water flow and in a location that provides sufficient space for adjustment, chemical replenishment, inspection and maintenance.

An upstream water filter is recommended where suspended solids may enter the hydraulic mechanism. Incoming water pressure and maximum water flow should be checked against the operating range of the selected dosing pump before commissioning.

The unit may be installed directly in the main pipeline or in a bypass arrangement. A bypass system can make it easier to isolate the dosing pump during maintenance while allowing operators to manage the water supply according to the farm treatment procedure.

The suction hose should be securely connected to the treatment-solution container, and the suction filter should remain correctly positioned in the prepared stock solution. Chemical compatibility must be verified before the system is started.

Routine maintenance includes inspecting the water filter, suction hose, seals, dosing valves, injection assembly and hydraulic components. Deposits should be removed when necessary, and worn sealing components should be replaced with parts compatible with the selected chemical.

When changing between incompatible treatment chemicals, the dosing system should be properly flushed according to the chemical supplier's instructions and the farm's safety procedure.

Commercial Poultry House Water Treatment: A proportional dosing pump can be installed in the poultry-house water control room after filtration and pressure regulation. The treated water is then distributed to nipple drinking lines serving broiler, layer or breeder houses.

Centralized Multi-House Poultry Project: For larger poultry farms, dosing equipment can be incorporated into a centralized water-treatment station serving several poultry buildings. Filters, pressure regulators, chemical tanks, bypass pipelines and water distribution equipment can be configured according to project requirements.

Pig Farm Construction: In commercial pig farm construction, the dosing system can be integrated into the main water room or individual building supply lines for compatible water sanitation and acidification programs.

Steel Structure Livestock Building: During new steel structure building projects, the dosing station can be coordinated with livestock equipment and utility pipelines to simplify installation and provide convenient access for daily inspection and maintenance.

Specific project capacity, chemical program, pipe dimensions and installation layout are designed according to actual farm conditions.

Q: What is the main purpose of this dosing pump?
A: It is designed to proportionally inject compatible disinfectants, acids and other liquid treatment concentrates into livestock drinking water systems.

Q: Does the dosing pump require electricity?
A: No. The referenced configuration uses water pressure as its driving force for proportional dosing.

Q: How does the dosing rate respond to changing water consumption?
