Mokon’s Leak-Master negative pressure system stops leaks in molds and processes without stopping production. This easily connected, portable unit controls water leaks and flow by means of a progressive cavity pump. The system “pulls” rather than “pushes” the water through the process. Instead of water being forced out, air is drawn into leaking areas around faulty “O” rings, holes in pipes or cracks in molds. Essentially, the system creates a vacuum to effectively stop the leak, so there is no need to shut down production for a mechanical repair.


The Leak-Master can be installed quickly for emergency use or as a standby for intermittent use.


The Leak-Master can be connected to any process circulating water system. It can be used in conjuction with a direct water supply, a temperature control system or as a booster pump to an existing water system where head losses cause processing problems.

Installation and Operation

The Leak-Master can be easily installed to your leaking process. To control the leak and flow of water to your process, the regulating valve is simply adjusted from the outside of the dcaibnet without the need for tools. Casters allows for complete portability.
