Overview
SEKO metering pumps are motor-driven positive displacement pumps designed for precise chemical injection in industrial processes. The Italian-made pumps excel in repeatable dosing accuracy (±1%) and are widely used where reliable fluid handling is critical. These pumps employ a reciprocating diaphragm mechanism, isolating the fluid from mechanical parts. SEKO offers both solenoid-driven and motor-driven models, with flow rates spanning from milliliters to hundreds of liters per hour across their product range.
Structure and Working Principle
The core components include a drive mechanism (solenoid or stepper motor), diaphragm assembly, check valves, and control electronics. The diaphragm moves via electromagnetic or mechanical actuation, creating suction and discharge cycles. Fluid enters the chamber during the suction stroke through the inlet valve, then is expelled under pressure through the outlet valve during discharge. Advanced models feature stroke length and frequency adjustments for flow control, with some offering 4-20mA or digital communication for process integration.
Key Features
SEKO pumps distinguish themselves with chemically resistant wetted parts—options include PTFE diaphragms and PVDF housings for aggressive fluids. Their modular design allows easy maintenance with tool-free diaphragm replacement in many models. Intelligent controls are another hallmark, with select pumps featuring self-calibration, leak detection, and adaptive algorithms to maintain accuracy despite viscosity or pressure changes. The PRO series models integrate IoT capabilities for remote monitoring and predictive maintenance.
Application Areas
Primary applications include water treatment plants for dosing disinfectants (chlorine, ozone), pH adjusters, and flocculants. In food production, they meter additives like vitamins or preservatives with food-grade compliance. The pharmaceutical industry uses them for precise reagent addition, while manufacturing facilities employ SEKO pumps for coolant circulation and chemical process control. Their ability to handle shear-sensitive fluids makes them suitable for biotechnology applications as well.
Maintenance and Precautions
Routine maintenance involves inspecting diaphragms every 3-6 months (or per operating hours), checking valve seats for wear, and verifying calibration. Always use compatible lubricants for O-rings and seals. Critical precautions include never operating the pump dry (which can damage diaphragms), ensuring proper venting of the fluid system, and avoiding cavitation by maintaining adequate NPSH. For hazardous chemicals, secondary containment and leak sensors are recommended safety measures.
B2B Procurement Guide
When sourcing SEKO pumps, specify the fluid properties (viscosity, temperature, corrosiveness), required flow range, and pressure conditions. For OEM integration, consider compact Econ models; for harsh environments, the Heavy Duty line offers enhanced protection. Lead times typically range 2-6 weeks for standard configurations. Bulk purchases (10+ units) may qualify for 15-20% discounts through authorized distributors. Always verify supplier certification to ensure warranty validity, as counterfeit pumps occasionally appear in secondary markets.
