Plunger head with stuff box packing. The plunger oscillates in the cylinder and displaces the liquid. The packing adjustment is achieved by the front-sided adjusting screw, which is also possible during operation. The lantern on the rear head end serves to drain the leakage or can be used as an area to flush, lubricate or seal the pump with suitable media.
The pump check valves are of cone type. This guarantees low wear, short pressure loss (NPSHR) and self-cleaning.
All wetted parts are fabricated from stainless steel and sealed by PTFE.
