Solenoid Diaphragm Pumps: Precision in Compact Form

SEKO's solenoid-driven diaphragm pumps are engineered for accuracy, reliability, and ease of use across a wide range of dosing applications.

Tekna Series – The evolution of solenoid dosing pumps. Just five models cover flow rates from 0.4 to 110 L/h with pressures up to 20 bar. Featuring a PVDF pump head and ceramic ball valves as standard, Tekna pumps offer full chemical compatibility. The long-life PTFE diaphragm—tested to deliver a 5-year working life—eliminates routine replacement. A stabilized multi-power supply (100-240 Vac) ensures consistent dosing performance regardless of power fluctuations. The intuitive programming menu, available in five languages, reduces setup time and simplifies operation.

Tekba Series – Digital solenoid dosing pumps with microprocessor control, available in manual, proportional (pulse), and analog (4-20mA) versions. Simple, reliable, and built for urban water treatment, wastewater treatment, ClO₂ dosing, RO pretreatment, and food & beverage applications.

Kompact & Komba Series – Compact, economical solenoid pumps with PVDF liquid ends, ceramic ball valves, and PTFE diaphragms. Flow rates up to 9 L/h and pressures up to 10 bar. Ideal for light industrial and commercial dosing tasks.

Mechanical Diaphragm and Plunger Pumps: Versatile and Robust

SEKO's mechanical-return diaphragm pumps offer a cost-effective solution for a broad spectrum of dosing requirements.

MS1 & MSA Series – Mechanical diaphragm pumps with aluminum or PPS housings. Flow rates up to 530 L/h and pressures up to 10 bar. Simple, durable, and easy to maintain—perfect for OEM installations and light industrial use.

PS2 & PS1 Plunger Pumps – For applications requiring high-pressure precision dosing, plunger pumps deliver flow rates from 1.5 to 1,000 L/h at pressures up to 20 bar. SS316L and PVC liquid ends ensure broad chemical compatibility, while the robust spring-return mechanism guarantees long service life.
