Canned Motor Pump Heavy Duty

Product Specification

BA SERIES CANNED MOTOR PUMPS

DESCRIPTION

Basic type (standard type)
The temperature of the conveying medium does not exceed 120 ℃, and the head does not exceed 100m. Other types of canned pumps are variants and improvements of the basic type, including dead and reverse circulation. This type of canned pump has the opposite direction of liquid flow for bearing lubrication, cooling, and motor cooling compared to the basic type.

The drive of an ordinary centrifugal pump is to connect the impeller shaft of the pump with the electric shaft through a coupling, so that the impeller and the electric motor rotate together and work. However, a Canned MotorPump  is an unsealed pump, and both the pump and the driving motor are sealed in a pressure vessel filled with the pumped medium.

This pressure vessel only has a static seal and is equipped with a wire group to provide a rotating magnetic field and drive the rotor. This structure eliminates the rotary shaft sealing device that traditional centrifugal pumps have, so it can achieve complete leak free operation.

It adopts international standard design, the maximum operating flow is 1200m3/h, the maximum head is 600m, the temperature range is -120-350°C, and the maximum pressure of the system design is 20MPa.

ADVANTAGES

(1) Long service life, automatic hydraulic thrust balance system combined with silicon carbide bearings to obtain high service life;

(2) High efficiency, optimized motor design and high-efficiency hydraulic research, achieved excellent energy efficiency;

(3) High reliability, advanced processing technology, high-tech CNC equipment and perfect testing to ensure the stability of product performance;

(4) Monitor bearing wear to realize online monitoring and automatic control;

(5) Secondary sealing to ensure the safety to the environmental even in the accident situation.

Precautions when selecting a canned motor pump: Generally, shielded pumps use a portion of the liquid conveyed to cool the motor, and the annular gap is very small, so the liquid conveyed must be clean. For conveying various liquid mixtures, if they produce precipitation, coking, or gelatinous substances, selecting a shielded pump (non slurry type) may block the shielding gap, affect the cooling and lubrication of the pump, and cause the graphite bearings and motor to burn out. Shielded pumps generally have circulating cooling pipes. When the ambient temperature is lower than the freezing point of the pumped liquid, it is advisable to use anti freezing measures such as accompanying pipes to ensure convenient pump startup. In addition, when starting the shielded pump, the opening sequence of the outlet and inlet valves should be strictly followed. When stopping the pump, the outlet valve should be turned down first. When the pump stops running, the inlet valve should be closed first and then the outlet valve. In short, the use of shielded pumps is completely leak free, effectively avoiding environmental pollution and material loss. As long as the selection is correct and there are no abnormal changes in operating conditions, there is almost no maintenance workload under normal operation. Shielded pump is an ideal pump for transporting flammable, explosive, corrosive, and precious liquids.

FEATURES

Canned motor pump is composed by canned motor and pump, the inner surface of the stator and the outer surface of the rotor are covered by a thin-walled non-magnetic corrosion-resistant metal, so the stator winding, the rotor core will not be eroded by the conveying liquid, due to they are completely separated. In addition, the impeller is directly installed at the shaft extension of the rotor, the entire rotor is immersed in the conveying liquid, no rotating parts extend outside, is a structure without leakage, so it has the following advantages

(1) Leak free, it is suitable for transporting toxic, explosive, flammable, purified, corrosive liquids;

(2) Complete seal, it is suitable for transporting liquids which is easy to oxidize;

(3) No mechanical seal, it is suitable for conveying high system pressure liquids, high melting point liquids, high temperature liquids, and low temperature liquids.

(4) Using medium as the lubrication, no need grease, no contamination to the transported liquid, no need of grease injection and drainage, either;

(5) Due to the motor and pump are coaxial integration, it is space saving, light in weight, compact design, easy to maintain and dismantle;

(6) The motor adopts water cooling or natural cooling, no fan, so the running vibration is less and the noise is lower.
