油式潤滑的真空幫浦，其最終真空壓力可達20mbar ， 且全部吸入的容積從每小時3M-250M立方。將壓力計與真空幫浦開關(guān)結(jié)合在一起，自動式的開關(guān) 可讓幫浦在壓力不足時才會作動，壓力足夠時即停止。過熱保護裝置，防止開關(guān)與電路板因過熱而損壞。空氣濾凈器可防止雜屑進入真空幫浦(內(nèi)含可替換濾芯)。請小心真空組件與機器上應(yīng)用的搭配，可保證無狀況壽命長久。當(dāng)吸入切消液時，底部排水縲絲旋開，即可排除。3M長的電源線搭配CEE或SCHUKO插頭。

MODULAR VACUUM UNITS 模塊式真空組件
結(jié)合儲氣與水過濾器功能，不需再追加分離器。
所有配件以節(jié)省空間為原則組裝而成。
可全部檢視水過濾，以及儲氣狀態(tài)提升安全性。
若要改變較大的儲氣狀態(tài)只需更換儲氣桶。
結(jié)合空氣濾凈器，雜屑分離器過電保護，自動壓力改變開關(guān)。 
目前有6M-63M立方幫浦、無油壓式幫浦可供選擇。

VACUUM PUMPS AND UNITS
We have all different kinds of vacuum pumps available to meet each individual need. Size and capacities range from 3m3/h - over 500 m3/h to guarantee optimal vacuum clamping fixtures whatever the circumstances.
Liquid ring pumps
Witte offers a liquid ring pump which combines vacuum supply and liquid separator in one. This pump filters gathering coolant during machining process and integrates it into its own water cycle excess fluid is returned to cycle of machining center.
Vacuum units
Operating vacuum required can be generated in many ways. Witte vacuum units feature the following:
?Oil lubricated vacuum pumps with an end vacuum rate of 0,1 mbar absolute at full suction
?Integrated pressure difference switch, which automatically switches the vacuum pump on or off thereby ensuring vacuum during machining, avoiding unnecessary idle running
?Protection switch which safeguards electric motor from overheating
?Air filter which protects pump from dirt (made of acrylic glass with an exchangeable air filter cartridge)
?Careful assembly of compatible components guarantee trouble-free and almost maintenance-free operation using Witte vacuum units in many applications
?Drainage screw for coolants which have been sucked in
?3m connecting cable with CEE or Schuko plug
