The Ametek Lamb 116353-00 is a two-stage, 5.7-inch tangential bypass motor for 220 to 240 volt supply. The bypass construction is the point of it: because cooling air never mixes with the air the machine is recovering, this is the motor family specified for wet pickup - carpet extractors, autoscrubber recovery, and any machine pulling water or cleaning solution through the airstream. Buyers are almost always technicians replacing a failed motor in a 240-volt extractor or commercial recovery machine.
Built for these use cases
- Carpet extractor vacuum motor replacement on 220 to 240 volt machines
- Autoscrubber and wet-vac recovery motors
- Two-stage central vacuum power units on overseas mains
- Commercial machines where exhaust must be routed out one side
- OEM service work on 240-volt bypass equipment
A bypass motor carries a separate cooling fan, so the air that cools the armature and field never mixes with the air being pulled through the machine. That separation is the whole reason bypass motors are specified for wet recovery work such as carpet extraction and autoscrubber recovery, where the airstream is carrying water, foam and cleaning solution. It also means the motor is not being cooled by whatever the operator happens to be picking up.
Tangential discharge routes cooling air out through a single side port, which lets the machine builder aim the exhaust deliberately - into a muffler, a sound baffle, or straight out of the cabinet. On extractors and compact commercial machines where the motor sits in a tight enclosure, that directed exhaust is often the difference between a motor that runs cool and one that heat-soaks.
Ametek Lamb part numbers are not interchangeable by diameter alone. Before ordering, pull the old motor and match four things: frame diameter, number of stages, discharge configuration and nameplate voltage. Two motors that share a body size can have completely different gasket surfaces, lead lengths and airflow paths, and a mismatch usually shows up as a motor that physically drops in but never reaches its rated suction.
We are not going to publish airflow, sealed-lift or air-watt figures for this motor. No source we can verify publishes performance data for the -00 suffix specifically. Figures widely circulated for the 116353-13 variant - 1250 watts, 240 volts, 6.7 maximum amps - belong to that suffix, and quietly reusing them here would be inventing a specification. If you need verified numbers for 116353-00 before you buy, contact us and we will pull the Ametek data sheet for the exact suffix.

Frequently asked questions
Why are no CFM or air-watt figures listed?
Because no source we can verify publishes them for the 116353-00 suffix. Numbers circulating for the -13 variant are for a different motor. We would rather say so than reprint a figure that may not describe what you receive.
Can this motor be used to recover water?
Yes. It is a bypass motor, which is the configuration specified for wet pickup because the cooling air path is completely separate from the recovery airstream.
What does tangential discharge change?
It exhausts cooling air through a single side port instead of around the housing, so a machine builder can direct that exhaust into a muffler or out of the cabinet. In a tight enclosure it helps the motor run cooler.
Is 220 volt the same as 240 volt here?
For this motor they describe the same nominal overseas supply band. Confirm the voltage stamped on the motor you are replacing before ordering.
What usually fails first on these motors?
Carbon brushes. A motor that surges or cuts in and out is usually telling you the brushes have worn past reliable contact with the commutator, and a fresh set can add hundreds of hours.
Discount Cleaning Products is an authorized dealer for Ametek Lamb vacuum motors and stocks the matching carbon brush kits, gaskets and mounting hardware alongside them. Our US-based team works with these motors every day across central vacuum systems, extractors, autoscrubbers and shop equipment, and can help you confirm frame size, stage count, discharge style and voltage against the motor already in your machine before you order.
