Filter Recommendation

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

Filter Type/Size

Series GA

Series GAT

5 Micron** (≤2 psid [0.14 bar] pressure drop)

Canister style (Fig. 2) or Fine Mesh style (Fig. 1)

Series GJ

Series GL

40 Micron* – Soft particles (≤ 4 psid [0.27 bar] pressure drop) 5 Micron* – Hard particles (≤ 4 psid [0.27 bar] pressure drop)

Canister style

Series GB

Series GC

Series GD

40 Micron* – Soft particles (≤ 2 psid [0.14 bar] pressure drop) 5 Micron* – Hard particles (≤ 2 psid [0.14 bar] pressure drop)

Canister style

Series CA

50 Micron* (no pressure drop)

Mesh style

*Micron = 4 x 10-5 inches **Micron = 10-6 meter

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 ensure pressure drop stays within an acceptable range
