Product overview：

Economical and practical ，pump coaxial

The new 2BV2 series pump,it’s compact design brings huge benefits in many aspects, high efficiency and muti-function ,which not only save space but also reduce water volume by 50%. The liquid quantity allowed to be entrained during operation is 8times of that ordinary pumps at the same suction capacity,it’s the difference between the coaxial design pumps and traditional pumps.which makes it more suitable for plastic and pharmaceutical machinery.

Safety and reliable.

When there are high requirements for safety and reliable,2BV2 has incomparable advantages.this series pumps can be made of different material or combination materials,including:stainless steel、bronze、ceramics、cast iron and ceramics lining.According to the specific demand，different materials can be chose to prevent corrosion.About quality ，2BV2 liquid pump is simple and reliable：the stainless steel shaft with both strength and toughness and the Optimized lubricant passages ensure that they can safety operation under a limited load with little maintenance.

General and ample supply

No matter where you use our 2BV2 liquid ring vacuum pump，only a few models can cover the world’s input voltage level,which can be reduce your inventory costs.2BV2 is equipped with wide voltage dual frequency motor(50Hz/60Hz) and protection grade IP55(temperature Grade F). no matter where it’s applied,some products can meet the requirements of voltage.2BV2 conforms to international standards and can be used in and filed of the world. ATEX cert. Is more suitable for flammable and explosive applications .the supply of 2BV2 series products is timely .

The compact design of the 2BV vacuum pump is characterized by a rotor mounted directly on the motor, eliminating the need for an aligned bronze impeller as standard to improve the pump's corrosion resistance. The compact design reduces the size of the 2BV by approximately 30% in the case of tight installation sites. Because of the low noise level of the 2BV, no muffling device is required, which saves space and cost.

The mechanical seal design, which comes as standard, virtually eliminates leakage and reduces equipment maintenance. The patented design of the flexible exhaust valve ensures that its entire operating range is in a stable condition.

The rotating part of 2BV is a impeller, which makes the working fluid form a liquid ring in the oval pump through rotation. At this time, the working fluid acts as sealing medium, compression medium and cooling medium at the same time, without wear and lubrication.

In the exhaust phase, the liquid ring gradually moves away from the wheel enough to discharge the pumping medium from the exhaust port in the axial direction.

Continuously injected replenishment fluid to compensate for the fluid carried away by the exhaust gas.

In the suction stage, the impeller gradually moves away from the hub and sucks the pumped medium axially from the suction inlet.

Because the impeller is eccentric with respect to the rotating liquid ring, the liquid moves back and forth in the space between the blades,

Just like the piston moves in the cylinder

It can pump and compress the pumped medium.

All design features of 2BV make it basically maintenance free. Oil free design does not need to replace the oil filter equipment. Under normal operating conditions, the mechanical seal of 2BV does not need to be adjusted regularly as the packing seal. The suction capacity of 2BV ranges from 6M3/H to 500M3/H, and the suction pressure can reach 33MBARA.
