Versatile self-priming magnetic drive pump with enhanced durability under abnormal operation

Features of SMX / SMX-F series

The SMX has a modular structure to handle liquids with increased specific gravities. Use of standard motors extends the range of liquid application.

Enhanced durability under abnormal operation

Our original self-radiation structure efficiently disperses bearing friction heat to protect the pump under abnormal operating conditions. In addition, our non-contact structure prevents contact between rear thrust face and bearing, to eliminate heat buildup during dry running.

Easy maintenance

The pump wet end can be removed from the motor as a complete assembly without dismantling, thanks to an additional rear casing support. The pump wet end comprises the minimum number of parts for easy maintenance.

Fast self-priming

The SMX requires no external self-priming chambers or valves. The gas-liquid separation design ensures fast self-priming. An exceptional self-priming duration of up to 4m in only 90 seconds is now possible.
