A new solenoid-driven FL10 diaphragm pump from KNF Neuberger Inc. (Trenton, N.J.) features bi-directional Image credit: KNF Neuberger, Inc.flow-tightness without additional check valves, as well as IP 65 protection. Targeting OEM customers, the pump offers a nominal liquid flow rate of 100 mL/min, simple linear flow rate adjustment and a maintenance-free expected lifetime of 10,000 hours.

The FL10 pump uses spring tension in the linear solenoid drive to keep it flow-tight in both directions when turned off, making additional check valves unnecessary and helping to reduce costs. Built for operation in demanding environments such as wet or dusty areas, the pump’s IP 65 protection class reduces the need for additional protection in the customer’s system. Fail-safe operation is ensured by sealing between the pump housing and the linear drive, and laser-welded head parts keep the pump leak-free.

Flow rate adjustment during the assembly process at KNF ensures consistent repeatability from pump to pump, saving calibration time when the pump is built into the user’s system. The frequency-controlled drive also allows OEMs to quickly and linearly adjust the flow rate.
