Maintenance
• Causes of malfunctions - solutions
1 -
Impureties or particles in the entrance cone could prevent the eductor from functioning properly. These
particles can been carried by a dirty suction rod or water. Follow the steps detailled "disassembly exit/
entrance cone” (page 14) to clean the suction chamber
2 -
A waterhammer may have moved the membrane of the control valve. To remove the membrane and
put back in its place, follow the steps detailled “disassembly the control valve” (page 15). Open and close
smoothly valves avoiding this.
3 -
The direction of assembly must always be respected. Be sure the arrow on the body of the eductor show
the flow direction (page 11).
4 -
The functioning of the eductor may be affected if the metering device cannot be turns or turns roughly
Follow the steps “disassembly metering device” (page 15) to set or replace the metering device.
5 -
The body of the eductor protects the entrance and the exit cone from bump and a filter from particles.
However, particles carried by water may damage these parts over time. Then, replace these by paying
attention to the flow rate of the spare pieces. Follow the steps “dismantling entrance/exit cone” (page 14).
6 -
Due to a bump or a crushing, the body of the eductor may been distorted or internal components broken.
Replace the eductor by a new one. If it seems fixable, you can request a price quotation.
7 -
The eductors are designed to work with foam equipment with a similar flow rate. The European standard
requires a pressure of 6.5 bar at the outlet for a pressure of 5 bar at the foam branchpipe inlet.
If the pressure loss is higher than 1.5 bar (hose too long or branchpipe too high
comparative to the eductor), the device will no longer working and can not suck up
the emulsifier.
As a reminder, each elevation meter between the eductor and the branchpipe raise the pressure loss of 0.1
bar. The eductor is designed to suck up to 1.5 meter above the emulsifier. Beyond, the device can not suck
up the emulsifier, except for specific design.
Depending on the bend radius, a 90° turn generate a significant pressure loss, any break or fold must be
avoided in the hoses.
8 -
According to the mode and frequency of use, leakage may appear at the metering device due to the wear
of gaskets. If this occurs, follow the steps “dismantling metering device” (page 15).
It is important to check, after each use, that no part is missing or damaged. Where necessary, please
replace it as soon as possible.
