The pre-filter lid seal is a key part that ensures the watertightness of the pump at the point of access to the basket. Made of durable elastomer resistant to chlorinated and salt water.
The seal is precisely shaped for a perfect fit on the body of MCB and MCQ pumps, thereby eliminating leaks even at higher operating pressure. Replacement is quick and requires no specialist tools.
We recommend checking the condition of the seal every year before the start of the season and replacing it preventively whenever the lid is removed. A properly functioning seal extends the service life of the entire pump.
