Frequently Bought Together

Price for both: $636.00


The LabStrong™ PU1190X1LS diaphragm pump is comparable to the Thermo Fisher Scientific™ Barnstead™ PU1190X1 diaphragm pump. The diaphragm pump can be used with the Thermo Fisher Scientific™ Barnstead™ NANOpure™ Infinity™ Retrofit Kit (PU896X3) and NANOpure™ DIamond™ water purification systems. The diaphragm pump is also used with the distribution Boost Pump (AY1268X1). The diaphragm pump provides outstanding quality at a lower cost than the competitor’s.

The function of the re-circulation diaphragm pump in the Thermo Fisher Scientific™ Barnstead™ NANOpure™ water purification systems is to recirculate purified water during inactivity. The re circulation process helps to ensure water purity and allows for on-demand use of water. When the diaphragm pump is used as a distribution Boost Pump, it helps to compensate for longer tubing runs and for water storage reservoirs above the level of a NANOpure™ water purification system or feed source. The high-quality pump provides optimal flow rates, constant pressure, and quiet operation.
