Product Description
Canned Motor Pumps
Canned motor pumps combine the motor and pump into a compact design. These seal-less pumps are ideal for applications that require handling toxic, explosive, expensive, hazardous, carcinogenic and corrosive fluids without leakage or emissions. In addition, canned motor pumps:
NO LEAKAGE OR EMISSIONS
Handles toxic, explosive, expensive, hazardous, carcinogenic and corrosive fluids without leaking during operation, shutdown or process upset conditions.
AIRTIGHT
Ideal for vacuum services or for fluids with high reactivity to atmosphere.
NO SHAFT SEAL
No dynamic mechanical seal. No gland packing.
NO EXTERNAL LUBRICATION
Pumped fluid provides cooling and thin film lubrication of motor and bearings. No lubrication levels to check or maintain.
VACUUM TO HIGH SYSTEM PRESSURE
Designs can be rated like pressure vessels to handle conditions from full vacuum to 5,000 psi / 35 MPa.
COMPACT DESIGN
Motor and pump are a combined, single unit. No alignment is necessary. Grouting and/or elaborate foundation design is eliminated.
QUIET OPERATION
Low noise levels are achieved since the motor is cooled without a fan. All rotating parts operate within the thick motor shell.
EXPLOSION PROOF
Certified by underwriting agencies around the globe with suitability for use in local electrical hazardous area locations as specified.

Chempump
Chempump NC series models are leakproof and offer secondary containment of the process fluid as well. These environmentally friendly Seal-less ANSI Pumps are the only canned motor pump to meet two industry specifications for seal-less pumps:
- ASME B73.3M Specification for Sealless Horizontal End Suction Centrifugal Pumps for Chemical Process
- Hydraulic Institute's Sealless Centrifugal Pumps Standard ANSI/HI-5.1-5.6 for both performance and dimensional standards
Other Chempump models include the Chempump Dynapump series, canned motor pumps that deliver dependable, leak-proof, economical pumping performance.
Rotary Guardian Bearing Wear Monitor
Every Teikoku seal-less ANSI pump comes standard with a TRG, Teikoku rotary guardian continuous bearing wear monitoring. The TRG is an electrical meter that continuously monitors both axial and radial wear, and shows the real-time progress of bearing wear and any incorrect rotor position. The TRG indicates any serious pump malfunction, and it can OPTIONAL.ly be connected to an alarming device.
