Tunze Hydrofoamer 9420.040 Silence Pump (9420.040)

TUNZE® Hydrofoamers Silence are specially developed pumps for TUNZE® protein skimmers DOC Skimmer and Master DOC Skimmer. They can also be used as replacement needle wheel pumps on any suitable skimmer available on the market. Additionally, they have a high air output at a very low power consumption and low operating noise.
The performance tables include a tolerance of +/- 15%. Depending on the skimmer reactor, the performance may vary due to the counterpressure of the water column.

Questions on Tunze Hydrofoamer 9420.040 Silence Pump (9420.040)

  • From eagle at 1/6/2015 1:02 PM
    • Hi, I'm getting conflicting data on the hydrofoamer silence 9420.040 output and the picture. On many other sites there is this same picture of the pump but the specs say max air is 850 lph. On Tunze site it has a pic of the pump with a pin wheel impeller and says new generation. The specs on that pump (9420.040) say 1200 lph air to 1000 lph water. Are the pumps you have listed a new generation that puts out 1200 lph air. Thanks for any clarification.
    • These are the new generation pumps with max. air flow of 1,200 lph to max. water flow of 1000 lph,
    • Do you find this question helpful?  Yes   No
