The 11620700 is the motor to reach for when a wet pickup machine needs a balanced replacement rather than a specialist one. It is a two-stage, 5.7 in Ametek Lamb bypass motor on 120 volts, rated at 104 CFM and 91.3 in of sealed water lift, which puts airflow and suction close enough together that it suits general-purpose wet/dry vacuums, extractors and car wash vacuum islands. Service technicians and equipment owners buy it as a direct replacement when the original motor has worn out its brushes and bearings.
Bypass construction is what makes it safe for water. The cooling air path is separate from the recovered air, so moisture and grit never cross the armature. Discharge is tangential, meaning exhaust exits to the side rather than around the full circumference, which is what some machine housings are designed around. If your existing motor discharges peripherally, check clearance before assuming a swap will fit.

Frequently asked questions
Is this motor safe for wet pickup?
Yes. It is a bypass motor, so recovered water and debris do not pass over the windings. That is the correct family for extractors, wet/dry vacuums and car wash vacuums.
What does tangential discharge mean for fitment?
Exhaust leaves the fan case to one side rather than around the full circumference. Machine housings are built around one style or the other, so check exhaust clearance if you are replacing a peripheral discharge motor.
How does it compare with the 11611900?
The 11611900 is a larger 7.2 in three-stage motor with much higher water lift. The 11620700 is the 5.7 in two-stage motor: less lift, lower current draw, and a smaller footprint.
How long do the brushes last?
Ametek publishes a carbon brush service interval of roughly 500 to 600 operating hours. Brushes worn shorter than 3/16 in should be replaced. A motor will typically accept two brush changes before the armature or bearings become the limiting part, which puts total service life in the 800 to 1200 hour range under preventive maintenance.
How do I confirm this is the right motor for my machine?
Match the Ametek part number first. If you are cross-referencing, confirm body diameter, number of stages, voltage, discharge type, overall height, bracket style and lead count against the motor currently in the machine before ordering.
