Hi,

 

We are about to purchase pulsation dampers for two new chemical injection pumps. The operating range is 5-20 lit/hr. The pump capacity is 75 lit/hr.

 

If we install the dampener based on the 5-20 lit/hr range and the operator needs to increase it to 30, 40 or 50 lit/hr, would that affect the dampener efficiency?

 

Would we need to install multiple dampeners to cover the whole range?

 

Regards,

Sherif

Hi Sherif,

For dampeners you should consult the pump's vendor who normally supplies the dampener. Let you try with Milton Roy or other big name .

My view.

Hi Breizh,

 

The pumps are actually Milton Roy :) They were installed 20 years ago and we are currently making changes to the discharge tubing. We are planning to purchase a couple of new dampeners. The operating capacity will be different from what was accounted for 20 years ago.

 

But thanks for pointing this out. I should go back again to them and see what they can do for us.

 

Regards,

Sherif
