  • piston pumps also wear out during such use and have to be replaced from time to time, which on the one hand results in system downtimes and, of course, on the other hand, the costs for repairing and installing the pump, for example the piston pump.
  • the diaphragm pump is driven by a rotatable cam, which drives a plunger attached to the diaphragm in an oscillating manner, the return stroke being effected by a spring.
