Vacuum Evaporator

Optional Utility Equipment For Rotary Film Evaporator Vacuum Pump

DIAPHRAGM PUMP (Dry Pump) :

• Suitable For GRFE 5 and 20 DryFast eco is the latest range of the cost effective and chemical resistant diaphragm pump from WELCH Vacuum products.
• The DryFast Eco two-stage diaphragm pump is an excellent choice for a wide range of laboratory vacuum applications such as distillation, drying, concentration, filtration, and aspiration, providing adjustable vacuum control with ultimate vacuum levels down to < 8 mbar.

Functional Benefits:

• Able to support a wide of chemical applications.
• Uses extra coated layers of PTFE liner for diaphragm, thus making it more robust.
• Dry running operation, Eco –friendly and low maintenance.
• Lightweight, durable, most suitable for 24x7 of continuous operation.
• Equipped with an adjustable control valve, precise settings of the flow and vacuum is easily achieved.

Key applications :

• 5-20 Liter Rotary Evaporation
• Vacuum Oven
• Vacuum Distillation
• Vacuum Network
• Vacuum Concentrator
• Gel Dryer
• Degassing Desiccation
• Aspiration
• Vacuum Filtration

Oil Sealed Vacuum Pump

These are oil-immersed, Rotary vane type pumps. The rotor, with two spring loaded vanes is mounted ecentric in the stator body, as the rotor rotates, the when's sweep the crecente shape air spacer twice in each revolution. There is in built non-return valve which prevents backflow of air. Manufactured from graded material/ all moving parts are precisely machined/ ground and assembled with close tolerances. this results in increased efficiency and long trouble free operating life.

Accessories:

• moisture trip. Inlet dust filter. Vacuum gauge with regulator. trolley for small pumps.
• Use oil : ENCLO-46 (HP) SAE-30 or equivalent, vacuum oil.
• vacuum measured by mcleod gauge at suction port of the pump.

Applications :

Distillation, dehydration and filtration processes existing electronic tubes, GLS lamps/ mercury vapor lamps and tubes, vacuum methodology, vacuum sublimation, vacuum impregnation, thin film coating, refrigerator and air conditioner servicing.
