Application Overview
Flushing of mechanical seals, on large industrial pumps, is used to extend the life of the seal by cleaning and/or cooling the seal. There are many methods for implementing seal flush, but all either recirculate fluid from various other points on the industrial pump (usually the output) or use an external source for the flushing stream.
In either case a step-up in pressure, and/or flow control may be required, and a small Micropump pump is often used for that purpose. Micropump gear pumps are well suited for this application because they provide a well-controlled, smooth flow, and are built of materials that provide chemical capability and the temperature range require for most applications.
Micropump gear pumps provide differential pressure and flow control needed either for re-circulation or when using an external flushing stream.
| PUMPING REQUIREMENTS |
MICROPUMP SOLUTIONS |
| FLOW RATE: 15 to 19 L/min (240 to 300 USG/hr) |
We have variable speed pumps with flows from 0.405 to 26.6L/min (6.4 to 421 USG/hr) |
