Product Description
Accurate chemical dosing is what keeps antiscalant, chlorine, pH correction and pretreatment programs under control, so DSTC supplies dosing pumps matched to each chemical and flow range. Typical applications include antiscalant, sodium hypochlorite, acid, alkali, coagulant, flocculant, biocide, corrosion inhibitor, and oxygen scavenger dosing.
For quotation, send chemical name/concentration, required dose ppm, system flow m³/h, discharge pressure, control signal, and whether the pump will be panel-mounted or skid-mounted.
Overview
A chemical dosing pump, also known as a metering pump or injection pump, delivers a controlled chemical dose into a water line. Correct pump selection protects equipment, stabilizes water quality, reduces chemical waste, and avoids under-dosing or over-dosing. DSTC supplies SEKO dosing pumps across Saudi Arabia with selection support based on chemical type, concentration, required L/h, discharge pressure, signal control, and wetted-material compatibility.

Frequently Asked Questions
Are SEKO dosing pumps suitable for RO antiscalant?+
Yes. SEKO solenoid diaphragm dosing pumps are commonly used for RO antiscalant because they provide accurate low-flow dosing and can be controlled manually, by pulse, or by 4-20 mA signal.
How do I size a chemical dosing pump?+
The pump is sized by system flow, target dose, chemical concentration, dilution ratio, discharge pressure, and control method. DSTC can calculate the required L/h and recommend the suitable pump model.
Do you supply spare parts for SEKO pumps?+
Yes. DSTC supplies genuine SEKO spare parts such as diaphragms, valves, tubing, injection valves, foot valves, and accessories, with calibration and service support.
Can the dosing pump be controlled automatically?+
Yes. Many dosing pumps can follow a flowmeter, controller, pH sensor, ORP sensor, chlorine analyzer, or PLC signal through pulse or 4-20 mA control.
Which chemicals can dosing pumps handle?+
With the right wetted materials, dosing pumps can handle antiscalants, chlorine, sodium hypochlorite, acids, alkalis, coagulants, flocculants, corrosion inhibitors, scale inhibitors, biocides, and oxygen scavengers.
