The Series 120 is a magnetically driven, cavity style gear pump. A cavity style gear pump captures fluid in the space between the gear teeth and the surrounding cavity to carry it through the pump. The magnetic coupling uses two concentric magnets to drive the pump without direct contact with the motor shaft, eliminating the need for a dynamic shaft seal.

Small Size
The miniature package size of the Series 120 delivers performance that is usually found only in much larger pumps.

Leak Free
The magnetic drive and Teflon® seals keep the fluid securely inside the pump and potential contaminants out.

Smooth Pulseless Delivery
Positive displacement, helical gears provide smooth, accurate fluid delivery that is proportional to motor speed.

Chemically Resistant
An extensive range of wetted material options assure compatibility with a wide range of chemicals.

Easy to Service
Series 120 pumps are easy to field service using a Micropump service kit and simple hand tools.
