My code is different, it has more letters
The /i after the 3M in the code stands for the latest motor efficiencies to meet EuP / ErP requirements. Previously there was also an A instead of E, again relating to the motor efficiency.
What do the other codes mean
The other codes are for seal materials: H = Carbon Ceramic Viton, HS= Silicon Silicon Viton, E=Carbon Ceramic EPDM
Which motor will you supply
We will supply the motor to the current regulations at time of purchase. We cannot supply pumps with motors out of regulation.
