Our comment: For units with serial number 253.061 and higher, an adjustment with silicate-free water is required after installation. For units with an older serial number, a software update must be carried out in addition to the adjustment mentioned above. Please refer to the operating instructions for this.
Product information "Double pump head for Testomat® 808 SiO2"
2x screws M3x40, M3x50
1x shaft extension
1x spacer plate
1x double pump head with hoses
1x hose extension
1x 1.5 mm Allen key
After replacement, the pump must be recalibrated in Testomat® 808 SiO2.
The adjustment is available from firmware version T808_83-003. Update the firmware of older versions before carrying out the adjustment! (serial numbers lower 253.061)
It is important to use water with a silicate content of 0 ppm for this adjustment, otherwise the adjustment of the zero point is faulty and leads to incorrect measurement results.
To ensure this, please use the silicate filter cartridge for the T808 SiO2, article 270344, specially developed for this process.
(For additional information and notes on the equipment required for the software update, see the operating instructions as well as the "Replacing the pump head in Testomat808 SiO2" document)

Dear customers, please note that the calibration of the Testomat® 808 SiO2 can only be carried out with silicate-free water. Therefore, please use the silicate filter cartridge specially developed for this purpose when replacing the double pump head (art. no. 40395) and the associated pump adjustment.The cartridge filled with the special resin is inserted into the sampling line of the unit before the inlet and removed again after the adjustment. The pump replacement instructions describe the use of the silicate filter, storage conditions and shelf life. After the first use, the filter can be used up to 10 times within one year for balancing. After one year, the filter must be disposed of.
