Canned Motor Pump

Canned Motor Pump

Precision Canned Motor Pumps are developed, based on the technical know-how from Nikkiso Co.Ltd., Japan. Canned Motor Pump is a centrifugal pump with pump and hermetically sealed electric motor mounted on single shaft thus eliminating the requirement of mechanical seal or other sealing device. Entire rotating assembly is immersed in the liquid, and motor stator and rotor are isolated from the pumped liquid with corrosion resistant, non-magnetic liner and sleeve. A part of the pumped liquid is bypassed through the motor, for cooling of motor and lubricating the bearing.

CASING

Axial suction and top centre line delivery. Smooth hydraulic passages for high efficiency. Volute type casing connected to liner disc and adapter plate.

IMPELLER

Enclosed/ semi-open type, statically and dynamically balanced. Hydraulic balancing of impeller achieved by means of automatic thrust balance arrangement.
Auxiliary impeller for bearing lubrication and motor cooling is also available.

SHAFT

Stainless steel shaft accurately machined and ground. It is supported by ceramic / carbon graphite sleeve bearings in motor which are lubricated by pumped liquid. A return passage for circulating liquid for cooling motor and bearing lubrication available through the shaft.

DIRECTION OF ROTATION

Clockwise viewed from driving end.

ELECTRIC MOTOR

2/4 pole, 3 phase, 415V, 50 Hz, Class of insulation F, H or C. Flame-proof and explosion proof construction with built-in safety devices available.

FLANGES

Standard : Drilled toANSI-B 16.5 Class 300.
Optional : Drilled to DIN/IS/ASA/BS.

ADDITIONAL FEATURES

Dry run protection device, single phase protection, over current and under current protection devices Winding temperature detector (ResistanceTemperature Detector andThermistor).
Bearing wear monitor Mechanical andElectrical.
Direction of rotation detector.

Canned Motor Pump - Leak-Free, Reliable, and Maintenance-Friendly Solution by Precision Sealless Pump

In today’s industries, where safety, efficiency, and reliability are paramount, Canned Motor Pumps have emerged as a game-changer. At Precision Sealless Pump, we are proud to be a leading manufacturer, supplier, and exporter of Canned Motor Pumps, delivering cutting-edge pumping solutions for critical and hazardous applications across the globe.

What is a Canned Motor Pump?

A Canned Motor Pumps is a sealless centrifugal pump where the motor and pump are integrated into a single hermetically sealed unit. This design eliminates the need for mechanical seals, which are typically the weakest point in conventional pumps, especially when handling toxic, corrosive, or volatile fluids.

Key Features of Our Canned Motor Pumps:

• 100% Leak-Free Operation : Thanks to the sealless design, our pumps ensure zero leakage - ideal for handling aggressive or hazardous chemicals.
• Compact & Space-Saving Design : The pump and motor in a single housing reduce the footprint and simplify the system layout.
• Low Maintenance : The pump and motor in a single housing reduce the footprint and simplify the system layout.
• Energy-Efficient Performance : Designed for high efficiency and low power consumption, making them cost-effective in the long run.
• Silent & Smooth Running : Quiet operation and low vibration levels improve workplace comfort and reduce wear and tear.

The stator is canned is canned in the air gap, confining the liquid in the rotor chamber. The pump liquid circulates through the rotor chamber, cooling the motor, and lubricating the slide bearing that support the rotor. The casting of the chamber forms a seal less enclosure that confines the liquid without any precision sealing.

Features:

• Sealless Design: The most distinctive feature of CMPs is their sealless design. The motor and pump impeller are enclosed within a single, hermetically sealed casing, eliminating the need for traditional shaft seals. This prevents leakage and ensures containment of hazardous fluids.
• High Reliability: The absence of mechanical seals significantly reduces the risk of failure and downtime. CMPs are known for their long service life and minimal maintenance requirements.
• Energy Efficiency: CMPs are designed to operate efficiently, reducing energy consumption and operating costs.
• Compact Design: Their compact footprint makes them suitable for installation in confined spaces.
• Quiet Operation: CMPs are relatively quiet compared to traditional pumps, reducing noise pollution in the workplace.
• Wide Range of Applications: CMPs can handle a wide range of fluids, including those that are toxic, corrosive, flammable, or radioactive.

Advantages:

• Zero Leakage: Eliminates the risk of fluid leaks, protecting the environment and personnel.
• Reduced Maintenance: Fewer maintenance requirements due to the absence of mechanical seals.
• Increased Reliability: Longer service life and fewer breakdowns.
• Increased Reliability: Longer service life and fewer breakdowns.
• Energy Efficiency: Lower energy consumption.

How CMPs Work :

• Fluid Entry: The fluid enters the pump casing through an inlet port.
• Impeller Rotation: The motor drives the impeller, which imparts kinetic energy to the fluid.
• Motor Cooling: The fluid flowing through the pump casing also serves to cool the motor, ensuring efficient operation.
• Fluid Discharge: The fluid is accelerated by the impeller and discharged through the outlet port.
