SEKO Pumps
SEKO is an Italian dosing-pump and chemical-metering company with roots going back to 1976.It is relevant for water treatment, cleaning and hygiene, chemical dosing, controllers, peristaltic and diaphragm pumps, dosing skids, and applications where repeatable chemical feed is a core control variable.
SEKO Pumps's position in pumps and pumping equipment is defined by product families such as centrifugal, multistage, submersible, dosing, booster, plunger, and high-pressure pump families.The portfolio is best understood inside raw water intake, RO/NF feed, transfer, boosting, chemical dosing, wastewater lift, and desalination hydraulics, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.
Representative series on this page include 3C TRIPLEX Series, Exacta Series and Kosmo Series.Selection should focus on flow, head, efficiency, NPSH margin, wetted materials, seals, and drive arrangement.These cues help users understand the brand's strongest fit before moving into the model index and product cards for finer comparison.

How to choose SEKO Pumps & Pumping
This section answers two questions: which main product families SEKO offers, and which parameters to compare before choosing a specific model.
Step 1: Choose a product family by application
The main families shown on this page are General Products. Start with the treatment objective, equipment format, and operating duty, then use the model index below to compare exact specifications.
Step 2: Confirm the model by key parameters
After choosing a product family, compare flow and head, materials, efficiency, and duty cycle. Replacement projects should also verify installation or loading conditions, interfaces, and compatibility with the existing system; new projects should consider operating practice, maintenance, and spare-parts or consumables availability.
