Bertoli Piston Pumps | PS34 12,000 L/h
Bertoli PS34 Self-Priming High-Pressure Piston Pump
HD Process supplies Bertoli piston pumps for high-pressure liquid processing and continuous production duties. The referenced PS34 is a self-priming, three-plunger pump designed to deliver controlled flow at pressures up to 70 bar.
The PS34 combines a forged AISI 316 liquid end, ceramic plungers and a heavy-duty drive arrangement. Bertoli identifies the unit as self-feeding by gravity, so the product supply and inlet arrangement must be considered during pump selection.

Information Required for Piston Pump Selection
Pump selection should account for the required flow, discharge pressure, product viscosity, solids or abrasive content, inlet conditions, operating temperature, cleaning cycle and preferred connection arrangement.
Contact HD Process with your product properties, required flow and operating pressure to confirm whether the Bertoli PS34 suits the duty.
