Safety Meets Economy
Increase safety, while minimizing risk to the environment, plant personnel and neighbors, by specifying TEIKOKU Canned Motor Pumps. TEIKOKU’s unique pumping solutions operate emission-free and are 100% leakproof by design, with secondary containment offered as standard to enhance corporate goals for safety and long term sustainability.
TEIKOKU Canned Motor Pumps offer unique solutions to the demands of Process Industries to utilize equipment that, while operating leak-free, performs with a high degree of reliability and efficiency. TEIKOKU’s Canned Motor Pumps more than meet this challenge.
Besides providing for safe, redundant control for total fluid containment, TEIKOKU pumps offer some remarkable performance advantages. Designed for long periods of time between maintenance (MTBM) intervals, pre-planned maintenance during scheduled downtime is achievable. TEIKOKU Canned Motor Pumps feature a minimal number of components that need to be monitored and serviced. Costly, time consuming alignment procedures and external lubrication are completely eliminated. And, because TEIKOKU Canned Motor Pumps are sealless, complicated seal support systems and seal maintenance are eliminated.
TEIKOKU Canned Motor Pumps: true secondary containment safety, highly reliable operation, cost-economy…and ZERO environmental impact.
MECHANICAL SEALS
Seal failure usually results in total shutdown and pumps offer no secondary containment.
SEPARATE MOTOR AND PUMP
Requires scheduled and proper alignment to maximize unit reliability and the life of bearings and couplings. Motors are exposed and require fan cooling. Foundation pads must be poured and are necessary to support the increased weight and reduce the danger of misalignment. More than 60% longer than similar sized canned motor pumps.
COMPLEX MAINTENANCE
Motor and bearing lubrication and vibration levels must be continually monitored to extend operating life.
ELEVATED NOISE LEVEL
Separate motor cooling fan and other rotating parts greatly increase operating noise levels.
MAGNETIC DRIVE PUMPS
THIN CONTAINMENT SHELL
Required for efficiency and subject to damage by driven magnet sets and subsequent leakage to atmosphere. No secondary containment.
MULTIPLE BEARING TECHNOLOGY EMPLOYED
Combination of oil and grease lubricated ball bearings and fluid lubricated sleeve bearings requires frequent monitoring for proper lubrication. Rotating sleeve bearings cannot be externally monitored.
DECOUPLING DUE TO PROCESS UPSET
Decoupling may lead to sudden catastrophic failure and rapid heat rise.
SEPARATE MOTOR AND PUMP
Requires scheduled and proper alignment to maximize unit reliability and the life of bearings and couplings. Motors are exposed and require fan cooling. Foundation pads must be poured and are necessary to support the increased weight and reduce the danger of misalignment. More than 60% longer than similar sized canned motor pumps.
NOISY FAN
Separate motor cooling fan and other rotating parts greatly increase operating noise levels.
NO LEAKAGE OR EMISSIONS
Handles toxic, explosive, expensive, hazardous, carcinogenic and corrosive fluids without leaking during operation, shutdown or process upset conditions.
AIRTIGHT
With a hermetic static seal of the unit secondary containment and no dynamic sealing of the rotating shaft, Teikoku pumps are 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.
VACUUM TO HIGH SYSTEM PRESSURE
Designs can be rated like pressure vessels to handle conditions from full vacuum to 5,000 psi / 35 MPa.
EXPLOSION PROOF
Certified by underwriting agencies around the globe with suitability for use in local electrical hazardous area locations as specified.
QUIET OPERATION
Low noise levels are achieved since the motor is cooled without a fan. All rotating parts operate within the thick motor shell.
FIELD REPAIRABLE
Minimal number and simplicity of wear parts makes field service quick and safe.
ELECTRONIC BEARING MONITORS
All TEIKOKU Canned Motor Pumps are supplied with bearing wear monitors.
ALL PUMPS PERFORMANCE TESTED
Every component of a TEIKOKU Canned Motor Pump, including the motor and hydraulics parts, are manufactured by TEIKOKU to the strict statistical quality control tolerances important to canned motor pump performance, where hermetic motor and hydraulic performance are linked by design. Every pump manufactured by TEIKOKU is tested and documented for performance and Net Positive Suction Head Required (NPSHR) before shipment.
