Overview

KASHIYAMA water seal vacuum pump LEM6 model from Japan. Our water seal vacuum pump consists of a circular housing and an impeller, with the impeller installed eccentrically with the housing. When an appropriate amount of water is placed into the casing and the impeller is rotated, the water will move and form a circular water film concentric with the casing through centrifugal force. As a result, a space sealed by blades is formed near the water film, and as the impeller rotates, the volume of this space changes, and continuous suction, compression, and exhaust are carried out to form an efficient pump.

KASHIYAMA water seal vacuum pump LEM6 type from Japan

Our water sealed vacuum pump consists of a circular casing and an impeller, with the impeller installed eccentrically with the casing. When an appropriate amount of water is placed into the casing and the impeller is rotated, the water will move and form a circular water film concentric with the casing through centrifugal force.
As a result, a space sealed by blades is formed near the water film, and as the impeller rotates, the volume of this space changes, and continuous suction, compression, and exhaust are carried out to form an efficient pump.
Recently, from the perspective of pollution issues, there is still a way to circulate sealed water instead of directlyThe method of connecting and draining to prevent various harmful gases contained in the inhaled gas from dissolving or mixing in water and being discharged.

Characteristics of LEH/LEM series

  • The ideal choice for discharging gases containing water vapor and water droplets.

  • Emissions and corrosive gases.

  • Due to the small number of friction components and *, it can withstand continuous operation.

  • Low noise, low vibration.

  • Continuous exhaust without pulsation.

  • Using mechanical seals as shaft seals is easy to maintain.

  • All models are Elmo type, which has higher efficiency in achieving pressure than the traditional Nash type.

  • It has a built-in constant flow valve and uses an appropriate amount of water supply system.

  • The LEH type is a two-stage pump used for high vacuum, while the LEM type is a compact and lightweight pump directly connected to an electric motor.

Please use for this purpose

    Structure and principle of pump

    泵的结构和原理 说明图Our liquid ring vacuum pump consists of a circular casing and an impeller, which is installed in an eccentric position together with the casing. When an appropriate amount of water is placed in the casing and the impeller is rotated, the water moves while forming a circular water film concentric with the casing under the action of centrifugal force.

    As a result, the water film and adjacent blades form a sealed space, and the volume of the space changes with the rotation of the impeller, continuously performing suction, compression, and exhaust, making it a very efficient pump.

    Recently, in order to prevent various harmful gases contained in inhaled gases from dissolving or mixing with water and being discharged, there is also a method of sealed water circulation that does not directly flow out.

    • Used for vacuum dehydration filter dehydration

    • Used for dehydration in the papermaking process of paper mills

    • It is very suitable for discharging gases containing water vapor and water droplets.

    • Can discharge flammable and corrosive gases.

    • Due to the scarcity of friction components, continuous operation can be tolerated.

    • Low noise and low vibration.

    • Continuous exhaust without pulsation.

    • The shaft seal adopts mechanical seal, which is easy to maintain.

    • All models are Elmo type, which has better efficiency in achieving pressure than the traditional Nash type.

    • It has a built-in constant flow valve and uses an appropriate amount of water supply system.

    • The LEH type is a two-stage pump for high vacuum applications, while the LEM type is a direct acting motor pump with a compact structure and light weight.
