Drain valve Seko

Purge valve for Seko Dosing Pump

The drain valve is an indispensable component of a metering pump system. Its primary purpose is to eliminate air or gases trapped in both the suction line and the pump head. This air purge plays a crucial role in ensuring efficient and accurate operation of the metering pump.

The presence of air in the dosing system can lead to a number of problems, such as loss of dosing accuracy, formation of bubbles in the liquid, clogging of fluid lines and even pump malfunction. Therefore, the bleed valve is essential to remove this air and ensure a continuous and uniform flow of the liquid through the system.

There are two types of bleed valve depending on the seal material:

• FKM-B (Viton) seals: particularly suitable for acidic products.
• EPDM seals: used for products such as soda and other alkaline products.

The Seko drain valve is compatible with Seko Tekba, Komba, Tekna, Kompact and Maxima. 

How do I know which bleed valve to choose for my dosing pump

When selecting the metering pump model or its spare parts, it is essential to take into account the coding found on the side label. This coding not only identifies the model, but also provides crucial information, such as the hydraulic characteristics, the materials of the various components, the power supply...

We consider the Seko Tekna model AKL800NHP1000 to explain the coding:

1. The first field is the model: AKL

2. The second field is the hydraulic characteristic: 800

3. The third field is the voltage: N

4. The fourth field is the head material: H

5. The fifth field is the installation kit: P

6. The sixth field is the gaskets: 1

In order to choose the correct purge valve it will be necessary to consider this field.

There are different types of seals:

 - FKM-B: also known as Viton, it is specifically used for acidic products.

 - EPDM: type of seal used for products such as soda, alkaline products, etc.

 - PTFE: also known as Teflon, universally resistant and highly leak-proof.

 - FFKM: used in applications where high resistance to chemicals, high temperatures and extreme conditions is required.

7. The seventh field is standard: 0

8. The eighth field is customizations:00

For this particular model, AKL800NHP0000 the appropriate purge valve would be code EM99106840 , choosing:

• Seals: EPDM 
• Range: Tekna
