We have a wide range of Pump and Tubing products stocked in the UK ready to ship

Longer pumps range of Micro Gear pumps are ideal for lab use, offering a brushless motor design with a stainless steel pump head.

Optional features allow the micro gear pump range to offer volume dispensing, copy numbers, pause time and calibration times. Speed output from the pump is also optionally available as well as pump start or stop status.

Flow rates for the micro gear pumps allow fluids to be dispensed from 86 mL/minute up to 2500 mL/minute. Fluids can be dispensed with particles present as long as they are less than 10 micron. Fluids up to 200 cSt in viscosity can also be pumped.


Mirco Gear Pump - Working Principle

A micro gear pump uses the meshing of gears to pump fluid by displacement. They are typically used for hydraulic fluid power applications.

A magnetic drive contains an inner magnet embodied in the pump head and connected to the driving gear, and an outer magnet connected to the motor shaft. The pole-to-pole alignment of the two magnets provides the driving motion to the pump head.
