  If the Gema Water Pump powder pump does not convey powder, start by checking the compressed air source to ensure it's between 6 and 8 bar. Also, inspect the pressure gauge of the local pressure regulator. Verify the control cable or control signals. Refill powder if it's empty. Ensure proper fluidization in the suction zone. If the conveying hose is clogged, empty it with compressed air or manually, being cautious of expelled powder.

  If the indicator on your Gema Water Pump doesn't light up, ensure the correct operating voltage is present at connection 2.1: PP07 should have +24 VDC, while PP07-S requires 110-240 VAC. If the voltage is correct, the indicator might be defective or incorrectly connected, in which case you should replace or correctly connect it. If neither of these solutions work, the main board may be defective and needs replacement or repair.

  If the Gema Water Pump powder pump conveys irregularly or has low powder flow, first, adjust the fluidization correctly if the powder is not fluidized well. Check if the hose backpressure is greater than 1.0 bar; if so, clean or replace any clogged or bent powder hoses and clean or replace clogged filter elements. If the pinch valve's service life has expired, replace it along with the associated protective filter element, and blow off or replace any contaminated hose connections.

Empty any clogged conveying or suction hoses with compressed air or manually, being cautious of expelled powder. Ensure the con...
