Mechanical Booster pump

• 


• - Displacement speed(60Hz) : 100 ~ 2400 m3/hr
• - Ultimate Pressure : 5 x 10-4 Torr

Mechanical booster pump(ATM moving type) consist of two lobed rotors mounted on parallel shafts in casing. The rotors have substantial clearance(0.1~0.6mm) between themselves and the housing. They rotate in synchronism in opposite directions at speed of 3500rpm. This is possible because a fluid is not used to seal the gaps between the rotors and the pump housing. The two lobes counter-rotate to continuously transfer gas in one direction through the pump to backing line. Bestech's mechanical booster pumps are using high-grade alloy and special coated rotor to wear resistance and to enhance stiffness. Also, the special mechanical seal provide longer life cycle and reliability.

  •Performance is very good.

  To get the efficiency inside casing because it is not the lubricating oil is

  stabilized even about the fume of vapor and solvent etc.

   

  •The better resistant to abrasion

  Inside contact surface is higher strongness, It can take the special

  treatment at surface as the demand that those are very strong resistant

  to abrasion.

   

  •The compatibility is good.

  BM type and B type which are having difference that is atmospheric

  starting method or non-atmospheric starting. It can use for your order to

  change their coupling easily.

   

  •ISO standards application.

  According to using ISO standards motor application, anyone can shift

  and change the motor easily at anyplace and anytime.

   

  •Used high precision gear with high hardness

  Used a high precision and the high grade hardness gear that can use

  with high-speed rotation. this gear has small vibration and small noise.

   

  •Solid disk type mechanical seal applications(selective application)

  Mechanical seal where applies solid disk of the high grade hardness, wear is

  less and durability are very good.

   

  •The double lip seal can use on both direction of pressure.(selective application)

  The double lip seal on the both direction that has the durability is good and the

  leakage very small so it has stable and high vacuum pressure.

   

  •The better stability and fast connecting magnet coupling application

  To make one body with magnet coupling and axis of motor that has stability

  when pump rotate with high speed. If Pump and motor have not rotate equally

  each other. that is, loaded deflection. Magnet coupling makes it's the rotating

  speed fast from motor.

   

  •Direction of suction line variously

  BM(B)12A, BM(B)24A, BI(B)36A can adopt the horizontal(H) or vertical(V) at inlet

  port suction's direction.

   

  •The displacement control possible which applies the inverter(selective application)

  BI12A, BI24A and BI36A applied the inverter optionally in order to control

  exhaustion.

  •13Pa(1.0×10-1Torr)에서 유효배기속도 측정 (Displacement exhaust speed measurement in 13Pa(1.0×10-1Torr)

  •도달압력은 냉음극전리 진공계를 사용하여 측정한 값이며 피라니진공계 사용 시 4.0×10-1Pa(3×10-3Torr)을 유지함

  (Because Arrival pressure makes use of cold negative pole ionization vacuum gauge is value that measure and keeps 4.0×10-1Pa(3×10-3Torr)at pirani vacuum gauge use)

  •상기값은 표준보조펌프 적용 시 측정된 값이며, 보조펌프의 성능에 따라 측정값은 가변됨(Ultimate pressure is value measured at standard assistance pump application, and measurement value is variable by assistance pump performance)
