Quattroflow QF5050S

Quaternary pharmaceutical pumps with flowrate 50 to 5.000

Multiple use stainless steel diaphragm pump, compact design.

Quattroflow QF5050S pharmaceutical pump is designed to offer a constant flow with low pulsation at all flow rates. It can pump a minimum of 50 liters per hour and pumps 5.000 liters every hour at maximum capacity. The four-piston pumping principle enables risk-free dry-running, low pulsation, self priming, and minimal particle generation. The design is more compact than similar pumps and in addition, the pump can be installed in different ways Besides the stainless steel multiple-use version there is also a single use version available.
