Selection Guide

Chemical Viscosity and Aggressiveness

Select wetted materials, such as PVDF or 316L stainless steel, that match the chemical properties of your specific dosing reagents.

Peak Hydraulic Throughput

Ensure auxiliary filters and screening equipment match the maximum design flow rate of the main water treatment train without excessive pressure drop.

Dosing Control Logic

Determine whether manual stroke adjustment, 4 to 20 milliamp flow-paced control, or residual-based closed-loop automatic control is required.

Available Floor Space

Verify skid dimensions and maintenance clearance zones for filter media replacement or pump servicing.

FAQ

Q: What data is required to size an automatic chemical dosing system?

A: You must provide the required chemical injection volume per hour, system operating pressure, chemical concentration, and whether continuous proportional control via flow meter feedback is needed.

Q: How are mechanical screens protected against jamming from heavy debris?

A: Screens feature automated overload protection sensors with torque limiters that trigger an automatic reverse cycle or shut down the motor to prevent structural damage when heavy objects jam the rake.

Q: What maintenance is required for sodium hypochlorite generators?

A: Routine maintenance involves periodic acid washing of the titanium electrode cells to remove calcium and magnesium scale deposits that accumulate during the electrolysis process.

Q: Can your dosing pumps handle viscous or corrosive polymers?

A: Yes. Depending on the chemical type, we configure systems with specialized diaphragm or progressive cavity pumps featuring PVDF or 316L liquid ends to prevent seal degradation.

Q: What documentation is included with auxiliary equipment shipments?

A: Each unit ships with an operation manual, electrical wiring diagrams, P and ID drawings, component data sheets, and a factory inspection checklist.

Q: What is the standard lead time for auxiliary water treatment machinery?

A: Standard catalog items ship within 4 to 6 weeks. Custom-engineered multi-pump dosing skids or special metallurgy units typically require 6 to 8 weeks.
