Suction and delivery valves for Seko pumps

Seko Pump Valves Invikta

For a correct operation of the dosing pump it is important that all the elements that compose it are in good condition. That is why we have the original Seko spare parts, so you can replace the parts in poor condition or worn and have a pump in perfect condition. 

Metering pumps are composed of two types of valves: the suction valve and the discharge valve.

The suction valve is located at the bottom of the metering pump. The transparent hose connects one end to the suction valve of the dosing pump and the other end to the foot valve that goes into the chemical.

The discharge or impulsion valve is the one located at the top of the dosing pump. The white hose connects one end to the discharge valve of the pump and the other end to the injection valve that allows the chemical to be injected directly into the pipeline. This injection valve has a mechanism to prevent water backflow. 

One of the requirements to choose one model or another of valves is the type of gaskets. We differentiate between Viton seals (FPM) or EPDM seals and one or the other will be chosen depending on the liquid to be dosed. 

The Seko suction and delivery valve is compatible with the dosing pumps of the Invikta series. 

How do I know which valve set to choose for my Invikta metering 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 model Seko Invikta KCS632AVEK00 to explain the coding:

1. The first field is the model: KCS

2. The second field the hydraulic characteristic: 632

3. The third field is the voltage: A

4. The fourth field corresponds to the material of the head and seals: VE

In order to choose the correct valves, it will be necessary to take this field into account.

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

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

5. The fifth field is the installation kit: K

6. The sixth field is customizations: 00

For this particular model, KCS632AVEK00 the appropriate valves would be code EM99070064 , choosing:

• Seals: EPDM
