Disassembling the Secondary Pump Head
Loss of small spacer fitting
Inside the secondary pump head is a small spacer fitting, which
can be dropped easily when removing the heat exchanger.
➔ Be careful when removing the heat exchanger.
Damage of pump piston
The pump piston has an excellent stability and chemical
resistance inside the pump head, but it is sensitive to shearing
forces from the side.
➔ Do not try to remove the pump piston from the rear.
➔ Do not use the piston for removing pump seals.
