PB type shielded electric pump

PB type (basic type) use: suitable for conveying temperature is not more than 150 ℃, not easy to vaporize the cleaning medium. ● Performance parameters: flow rate: ≤ 500 m3/h head: ≤ 150m power: ≤ 315kW

SC magnetic pump

The product change seal is static seal. The driven part of the coupling is located inside the machine body, the shaft does not need to extend out of the machine body, and the shaft sealing device is canceled. It has good buffer vibration absorption ability, compensates for the displacement change of the system, and improves the stress of the shaft system. Synchronous rotation within the rated torque, no friction parts, long service life; The special isolation sleeve design effectively reduces eddy current loss. When overloaded, the main driven shaft can slip in a short time, play the role.

Low cavitation margin magnetic pump

The magnetic pump is composed of a motor, a magnetic coupler, a centrifugal pump, a base and other components. Its working principle is to use a magnetic coupler to transmit power. When the motor drives the outer magnetic rotor of the magnetic coupler to rotate, the magnetic lines of force pass through the air gap and the isolation sleeve., Drive the inner magnetic rotor connected to the impeller to rotate synchronously, so as to realize the contactless transmission of power and convert the dynamic seal into a static seal. Since the pump shaft and the inner magnetic rotor are completely enclosed by the pump body and the isolation sleeve, the problems of "running, emitting, dripping, and leaking" can be solved, and the safety hazard of pump mechanical seal leakage can be eliminated.

PBX type (small flow high lift type)

PBX type (small flow and high lift type) ● Purpose: It is suitable for conveying cleaning media with temperature not more than 150 ℃, small flow and high lift demand. ● Performance parameters: flow rate: ≤ 12.5 m3/h head: ≤ 125m power: ≤ 45kW

PBZ type (self-priming type)

PBZ type (self-absorption type) ● application: suitable for pumping cleaning medium with temperature not more than 150 ℃ from underground liquid tank. ● Performance parameters: flow rate: ≤ 50m 3/h head: ≤ 80m power: ≤ 45kW self-priming height: ≤ 6m

PBCG type (anhydrous cold ultra high temperature type)

PBCG type (anhydrous cold ultra-high temperature type) ● application: suitable for the transmission of high temperature cleaning medium below 400 ℃, without water cooling, high efficiency, energy saving and environmental protection. ● Performance parameters: flow rate: ≤ 500 m3/h head: ≤ 150m power: ≤ 220kW

High pressure magnetic pump

• Structural features Working principle The magnetic pump is composed of a motor, a magnetic coupler, a centrifugal pump, a base and other components. Its working principle is to use a magnetic coupler to transmit power. When the motor drives the outer magnetic rotor of the magnetic coupler to rotate, the magnetic lines of force pass through the air gap and the isolation sleeve., Drive the inner magnetic rotor connected to the impeller to rotate synchronously, so as to realize the contactless transmission of power and convert the dynamic seal into a static seal. Since the pump shaft and the inner magnetic rotor are completely enclosed by the pump body and the isolation sleeve, the problems of "running, emitting, dripping, and leaking" can be solved, and the safety hazard of pump mechanical seal leakage can be eliminated.

Multistage magnetic pump

The product change seal is static seal. The driven part of the coupling is located inside the machine body, the shaft does not need to extend out of the machine body, and the shaft sealing device is canceled. It has good buffer vibration absorption ability, compensates for the displacement change of the system, and improves the stress of the shaft system.
