SEKO Dosing Pump Price: Why Solenoid, Mechanical and Hydraulic Models Differ

SEKO dosing pump price makes sense only once you know which kind of pump you are asking about. The Italian manufacturer covers a wide range: solenoid diaphragm pumps such as the Tekna, Kompact and Invikta series, mechanical diaphragm pumps such as Kosmo, MS1 and MSA, and hydraulic diaphragm pumps such as Nexa and Nyva. As a general pattern, solenoid pumps sit lowest, mechanical diaphragm pumps in the middle and hydraulic diaphragm pumps highest. Within one series, more control functions, a larger size or a special head material push the quote up. So the question "how much is a SEKO pump" needs a series and a configuration before it has an answer. This article gives no figures. It explains what drives the quote, for buyers and design engineers.

SEKO dosing pump price starts with the product line

Solenoid diaphragm pumps. No motor or gearbox, simple construction, suited to small feeds. The Tekna literature says five models cover 0.4 to 54 L/h at up to 20 bar, with a PVDF head and ceramic balls as standard and an IP65 housing. Kompact is the simpler line, and Invikta addresses more control needs.

Mechanical diaphragm pumps. Kosmo, MS1 and MSA use a motor to drive the diaphragm, giving higher flow and continuous duty.

Hydraulic diaphragm pumps. Nexa and Nyva handle higher pressure and harsher duties, with more complex construction and the highest price.

For the same flow, the gap between product lines is usually far larger than the gap between models within one series.

Within solenoid series: control functions set the tiers

At the same flow, SEKO solenoid pumps come in manual versions, versions that accept external signals, and versions with built-in measurement and control. Control is the main reason a solenoid SEKO dosing pump price moves:

Manual frequency setting only: lowest cost.
Pulse, 4–20 mA and level switch inputs: higher.
Built-in pH, ORP or chlorine measurement with closed-loop control: higher again, but no separate controller is needed.

Buy the control you will actually use. Equally, if the site needs a DCS signal, do not save on a manual model; retrofitting later costs more.

Mechanical and hydraulic pumps: size and materials

For mechanical and hydraulic diaphragm pumps, SEKO dosing pump price follows size and liquid end material:

Higher flow needs a larger motor, diaphragm and head.
Higher pressure needs hydraulic diaphragm construction, which costs clearly more than mechanical.
Liquid ends step up from plastics to stainless steel to special alloys.

Explosion-proof or variable speed motors, electric stroke control and multiplex heads all raise the price further.

Pump head material and accessories

Tekna pumps come with a PVDF head as standard, and PVDF suits most chemicals used in industry, wastewater and drinking water. Other materials are chosen through the model code and change the SEKO dosing pump price.

SEKO solenoid accessory kits commonly include an injection valve and a foot valve with strainer; what ships with a given pump should be checked on the quotation. Back pressure valves, relief valves, pulsation dampeners and calibration columns are normally quoted separately.

Service and spares belong in the comparison

Half the value of an imported pump is support. Ask whether the local distributor stocks spares, how quickly diaphragms and valve kits arrive, whether commissioning is charged and how long the warranty runs. Buying one or two years of wear parts with the pump often gets a better unit cost and avoids downtime later. Put these costs next to the SEKO dosing pump price when you compare offers.

Selection mistakes that inflate SEKO dosing pump price

One is oversizing. A pump one size too large spends its life at low frequency or short stroke, accuracy suffers and you paid more. Another is ignoring back pressure: a solenoid pump feeding a near-atmospheric point will siphon and over-feed unless a back pressure valve is added, and that accessory should be in the budget. A third is overbuying control, such as a measuring and control unit on a small site that only needs fixed manual dosing.

What to align before comparing SEKO dosing pump price quotes

Same series, model, flow and pressure size.
Control: manual, external signal or measurement and control.
Head, diaphragm, ball and seal materials.
Supply voltage and explosion protection.
Accessory list, tax, freight and delivery time.

Without matching configurations, two quotes cannot be compared. Ask too whether the pump is fully imported or locally assembled and how long spares take.

Chemical, concentration and temperature.
Maximum and normal flow in L/h and discharge pressure.
Control: manual, pulse, 4–20 mA, measurement and control.
Site: indoor or outdoor, protection needs, power supply.
Quantity and required delivery.

Conclusion

SEKO dosing pump price is set mainly by product line: Tekna, Kompact and Invikta solenoid pumps at the lower end, Kosmo, MS1 and MSA mechanical diaphragm pumps in the middle, Nexa and Nyva hydraulic diaphragm pumps at the top. Within a series, control functions, size, materials and options make the difference. Choose the series by duty, set the configuration by need, then compare prices.

FAQ

How much does a SEKO dosing pump cost?

It depends on series and configuration; a solenoid pump and a hydraulic diaphragm pump are in different tiers. Send your duty for a configured quote.

Why do quotes for the same model differ?

Control functions, head material, accessories, tax and delivery time all affect the SEKO dosing pump price, so align configurations before comparing.

Does a Tekna pump need a different head?

The standard PVDF head and ceramic balls suit most water treatment chemicals; choose another material only for special liquids.

Is a solenoid SEKO dosing pump price always lower than a mechanical one?

At the same flow it usually is, but a high-end solenoid pump with measurement and control can approach a basic mechanical pump.

Which spares should I buy with an imported pump?

Diaphragm, balls and seats, seals, injection valve and foot valve, enough for one replacement cycle.
