Analysis of ph values on site as well as support on product selection for the specific application.

The problem

The primary challenge was the extreme low pH levels, ranging from 2 to 3.

The solution

To address this specific challenge, Tsurumi 80SFQ27.5 Stainless Steel pump was deployed, renowned for its robust resistance to the harshest pH conditions. With its double mechanical seal encapsulated within the oil chamber, thereby avoiding direct contact with the corrosive medium, this pump boasts an extended operational lifespan, surpassing the longevity of comparable alternatives.

Specifications SFQ

In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, agitator, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
