01

Single stage, single action, axial intake and exhaust, simple structure, and convenient maintenance

09

When the overflow parts are made of stainless steel of different grades, they can meet different anti-corrosion requirements;

05

Impeller diameter greater than Φ For rotor of 200 specifications, the shaft seal position is equipped with a sheath shaft;

13

2BE1 * * *-0, wide suction range, when the pump is low, the suction pressure can reach 33 mbar (ABS), with the upper stage ejector, the suction pressure can be lower than 33 mbar (ABS);

02

The exhaust port equipped with a flexible valve plate can automatically adjust the exhaust angle to make the pump operate efficiently under different suction conditions;

10

When the overflow parts are sprayed with special materials, the anti-corrosion cost of a large-scale water ring vacuum pump can be reduced. Its smooth surface can also effectively reduce the precipitation of ash-like substances and slow down the scaling process;

06

The axial and radial loads of the pump are respectively borne by two groups of bearings. The bearing structure is improved to ensure the long-term continuous and reliable operation of the pump;

03

Equipped with an automatic drain valve to control the starting liquid level of the pump to avoid overload starting;

11

When the anti-cavitation device is installed on the water ring vacuum pump, the operation of the pump under high vacuum can be effectively improved.

07

When equipped with a heat exchanger, the working fluid can be recycled and the water loss can be reduced. Through the self-priming capacity of the vacuum pump, the cooled working fluid is sucked into the pump without an additional pressurization device;

04

The packing gland is a half structure, which can be removed as a whole, making it more convenient to replace seasoning;

12

When the inner cavity of the pump body is lined with vulcanized rubber, the anti-corrosion ability of the pump body can be improved;

08

Ordinary materials are adopted, which can meet the general use requirements;

14

2BE1 * * * - 1, the low suction pressure can reach 140mbar (ABS), and the recommended high-efficiency suction range is 160 ~ 1013mbar (ABS);

15

The end face of the impeller adopts a grading design, which reduces the sensitivity of the pump to dust in the medium and water scaling. The structure of the impeller ring is improved and the structure of the impeller is improved. The extracted gas is allowed to contain nongranular dust;

16

By adjusting the assembly angle of the seal body, the function of internal circulation or external supply of cooling water of the seal can be realized to meet the needs of different shaft seals. By connecting the leakage hole of the stuffing box, the dripping coolant can be led to the designated place, which meets the requirements of environmental protection. Small size pump has two shaft seal types: packing and mechanical seal;

17

2BE1 101 ~ 253 water ring vacuum pump, the pump body and side cover are connected by a pull rod. 2BE1 303 ~ 705 water ring vacuum pump, the pump body, and side cover are connected by a flange, which ensures the overall rigidity and anti-vibration ability of a large-scale water ring vacuum pump. When the maintenance space is small, horizontal assembly and disassembly can be adopted;
