Spring Pumps
Plunger piston and mechanical diaphragm dosing pumps
Motor driven dosing pumps need to be robust, reliable and able to run on their own without supervision. SEKO’s entry level offering in motor driven pumps is the Spring series. Three sizes of mechanism and a wide selection of models with varying performance profiles allow the user to find the appropriate solution for almost any application, offering accurate dosing even under fluctuating pressure conditions.
• Capacity range: up to 1200 l/h, up to 20 bar
• Wetted parts: SS 316L, PVC, PP and PVDF
Features a spring return mechanism in an aluminium housing. These pumps always deliver robust, affordable and efficient power. They offer flexibility in stroke length and motor speed which are separately controllable. Thanks to the mechanically actuated diaphragms, SEKO’s Spring pumps can be used almost universally in low pressure applications with the additional benefit of being a zero- leakage solution.
The range also features
• Piston available as standard in SS316 or ceramic
• Mechanical diaphragm in PTFE
• Every pump can be equipped with an electric actuator which accepts a 4 – 20 mA signal
Spring PS1
Plunger piston dosing pumps
The PS1 series piston dosing pump offers a flexibility of choice combining different pump head and engine power options that ensures a solution for almost any eventuality or application.
The PS1 series’ performance achieves flow levels between 1.5 and 304 l/h at pressure up to 20 bar
Each model can be configured with 2 different stroke rates.
Stroke lengths can be set automatically or manually using the AKTUA Kit which uses a 4 – 20 mA signal.
Spring PS1 is supplied with a 3 phase electric motor with IP55 protection. Optionally available on request is a single- phase motor.
The PS1 12 VDC range achieves flow rates between 34 and 350 l/h at up to 20 bar
Spring PS2
Plunger piston dosing pumps
The PS2 series piston dosing pump also offers multiple combinations of pump heads and motor power that enables it to adapt to a large number of applications.
The PS2 achieves flow rates of between 40 and 1000 l/h with a pressure up to 20 bar. Whilst having similar features with the PS1 Series, PS2 Series is also flexible, being able to alter its hydraulic characteristics thanks to a bigger size of piston and longer stroke length, which therefore alters the flow rate and power.
Like PS1, PS2 pumps have a spring-loaded mechanism in an aluminium housing, and each model can be configured with 2 different stroke rates.
Stroke lengths can be set automatically or manually using the AKTUA Kit which uses a 4 – 20 mA signal.
PS2 pumps are supplied as standard with a 3 phase electric motor, though a single-phase is available on request, both with IP55 protection.
Spring MS1
Mechanical diaphragm dosing pumps
Mechanical diaphragm dosing pumps MS1 series offer several combinations of pump heads able to adapt to a large number of applications.
The MS1 Series achieves flow rates between 5.5 and 1200 l/h with a pressure of up to
16 bar. Multiple combinations of pump head and motor power provide options in selection of the optimal combination most suited to the specific application.
The MS1 pumps have a spring return mechanism in a single aluminium housing.
Each model works with 3 different stroke lengths.
Stroke lengths can be set manually or even automatically, by using the AKTUA Kit
based on a 4 – 20 mA signal.
In addition, Spring MS1 pumps can be supplied with a single or three-phase electric motor with IP55 protection.
The MS1 12 VDC range achieves flow rates between 23 and 620 l/h at up to 16 bar.
