Filter Recommendations
Pump life increases with fluid purity. Micropump recommends
using as fine a mesh as possible. The recommendations below are
based on Micropump’s experience in optimizing pump life.
Filter Location
Open System: Inlet side of pump
Closed Loop System: Inlet or outlet side of pump

Troubleshooting
If units will not prime:
- Reduce pressure drop across filters
- Remove clogged passages or debris
When pumping higher viscosity fluids:
- Increase the size of the filter to insure pressure drop stays
within an acceptable range
