Spring PS2
Spring-return plunger piston dosing pump
• Flow rate range: 40 - 1,000 l/h, up to 20 bar
• Wetted parts: SS316L, PVC, PTFE, FPM, EPDM and Ceramic

The PS2 series of piston dosing pumps o ers

multiple combinations of pump head, motor power
and stroke lengths that enable it to be arranged in
several hydraulic con gurations, making the range
suitable for multiple applications.
PS2 pumps have a spring-return mechanism in a
robust aluminium housing, and each model can be
con gured with two di erent stroke rates. To adjust
the ow rate of the pump, the stroke length can be
adjusted manually or even automatically, by using
the Aktua kit controlled by a 4 - 20 mA signal or by
a pulse-emitting water meter.
PS2 pumps are available with a 3-phase or a single-
phase electric motor, both with IP55 protection.

Spring PS1
Spring-return plunger piston dosing pump
• Flow rate range: 1.5 - 304 l/h, up to 20 bar
• Wetted parts: SS316L, PVC, PTFE, FPM, EPDM and Ceramic

The PS1 series is designed for applications that

require lower ow rates than the PS2 series while
o ering multiple combinations of pump head,
motor power and piston stroke length. This achieves
multiple hydraulic characteristics for adapting to a
large number of applications.
Like PS2, each model can be con gured with two
di erent stroke rates and is available with 3-phase
or single-phase motors, both with IP55 protection.
Versions with a 12 Vdc motor are available that
achieve ow rates between 34 and 350 l/h at
pressure up to 20 bar.

Spring MS1 AVS

Spring-return diaphragm pump with Assisted Vacuum System®
• Flow rate range: 450 - 1,200 l/h, up to 4.5 bar
• Wetted parts: SS316L, PVC, PP, PVDF, PTFE, FPM, EPDM and Ceramic

The AVS (Assisted Vacuum System®) is a technical

solution patented by SEKO that helps overcome
the typical functional limitations of pumps with
a spring return. Using this mechanism allows
pump performance to be improved by allowing
dosing frequency to be raised (stroke/min) without
compromising diaphragm lifespan.
Thanks to AVS, Spring MS1 AVS can reach a
ow rate of 1,200 l/h while keeping noise and
mechanical stress at a reduced level. Each model
can be con gured with two di erent stroke rates
and is supplied with a three-phase 2-pole electric
motor with IP55 protection.

Spring MS1
Spring-return mechanical diaphragm dosing pump
• Flow rate range: 5.5 - 500 l/h, up to 16 bar
• Wetted parts: SS316L, PVC, PP, PVDF, PTFE, FPM, EPDM and Ceramic

The MS1 series o ers multiple combinations of

pump head motors, stroke lengths and materials
that allows operators the chance to select the
optimal combination appropriate to the speci c
application in hand.
Being membrane pumps, they represent an
absolutely safe and leak-free solution to be used
wherever chemical leaks, that are typical of plunger
piston pumps, are not acceptable.
To change the ow rate of the pump, the stroke
length can be adjusted manually with a knob or
even automatically by using the Aktua kit
controlled by a 4 - 20 mA signal or by a pulse
emitter water meter.
Spring MS1 pumps can be supplied with a single or
three-phase electric motor with IP55 protection, as
well as with a DC motor working at 12 Vdc range
that allows the pump to achieve ow rates between
23 and 620 l/h at pressure up to 16 bar.

Numerous Tekna models are available, with analogic or digital interface, to satisfy almost any request from
the market.
Tekna delivers reduced energy consumption thanks to an embedded stabilised multi-range power supply
(100 – 240 Vac, 50/60 Hz). Thanks to the SEKO patented algorithm, the solenoid only draws the power strictly
required to activate the pump, based on the actual working conditions, which improves pump e ciency and saves
energy. The algorithm also compensates for any uctuation of the power supply voltage, for giving a precise and
accurate dosage in any condition.
Tekna is also available in ATEX standard-compliant versions, with constant or proportional dosage functions and a
digital interface. This model comes with a SS316L pump body as standard.

Kompact
Compact wall-mounted solenoid-driven dosing pumps
Kompact is a range of simple, reliable and compact wall-mounted solenoid-driven pumps. Designed to provide an
e ective response to the di ering needs of the market, the series comprises multiple models, both with analogic and
digital interfaces, to meet the most common installation conditions.
• Flow rate range: 3 l/h @ 10bar; 5 l/h @ 8bar
• Wetted parts: PVDF, PTFE, EPDM, FKM-B and Ceramic
• Analogue and digital range with constant or proportional dosage

Features
• Pump body in PVDF • DPT: Multifunction proportional dosing
• Kit available in PVDF or PVDF-T (4 - 20 mA/pulse), digital interface
• AMS: Constant, with analogic • DRP: Instrument-pump with pH/ORP input,
interface (potentiometer) digital interface
• AML: Constant with level, analogic interface • Available with special seals in FFKM
• AMC: Proportional dosing (pulse), analogic interface

Kompact has been designed as a basic range of solenoid-driven pumps for less demanding applications without
compromising on robustness and reliability.
With Kompact, SEKO has struck the perfect balance between using premium components that guarantee full
chemical compatibility in multiple applications while ensuring a ordability for the operator.
To satisfy every installation need, the range o ers ve di erent models, for constant and proportional dosages;
three with an analogic interface (potentiometer) and two with a digital interface (keyboard and 2x8 display).
