7906-26

High-Flow Diaphragm Oil-Free (Dry) Vacuum Pump
Features

• Two-stage pumps for quicker and more efficient vacuum pumpdown
• Quiet operation
• Very low maintenance
• ON/OFF Switch and internal protective thermal switch for the motor
• Vibration isolating feet

Ilmvac MP Series Standard Duty Membrane Vacuum Pumps are dry and oil-free for minimized maintenance. These high-flow units operate at 125 LPM and 222 LPM and both draw to 8mbar pressure (29.85"Hg vacuum). This deep vacuum makes it ideal for Vacuum Ovens, Glove Boxes and Vacuum Chambers. These pumps are suitable for applications for dry, moist or ethanol vapors.

Standard Duty Dry Vacuum Pump
Features

• Lightweight, compact and quiet
• Continuous oil-free Pumping
• Non-Corrosive
• Vacuum to 9Torr (29.6, in. Hg)
• No water or oil:  dry vacuum,
• Low maintenance, easy to replace worn parts with a Repair Kit
• Repairs easy, even "do it yourself"

These oil-free pumps are compact, economical and ideal for a variety of general vacuum applications. Simplicity is the key to the economical aluminum design of the pump. As the piston wobbles, air resistance on upward stroke expands Teflon seal on the piston to increase its efficiency while compensating for the wobble action.

Chemical Duty Dry Vacuum Pump
Features

• Features Advanced Vapor Management(AVM) for adjustable vacuum control
• Chemical Resistantwetted parts tolerate all routine laboratory solvents/corrosives
• Quiet, sleek and compact

Welch Dry Fast Chemical Duty Dry Membrane Vacuum Pumps are oil-free for minimized maintenance and maximum resistance to aggressive vapors. All parts that come in contact with vapors are made of PTFE pr similarly resistant materials. The model 2034B-01 has a flow rate of 25 LPM and an ultimate pressure of 9 torr (12 mbar or 29.6" Hg vacuum) making it a powerful tool for rapid drying and evaporation in small vacuum ovens, benchtop rotovaps and chemical duty filtration.

Mini Vacuum Pump for Laboratories
Features

• Low price vacuum pumps for filtration, drying and degassing
• Standard and chemically resistant models
• Extremely low noise and vibration with twin head design
• Plug and play wide-range power adaptor

These compact new models are comprised of a small twin head diaphragm pump enclosed in a robust housing with a wide voltage power adaptor. They are extremely quiet and virtually inaudible over the typical background noise of a lab.

Standard duty pumps (MP) are available for pumping air and chemically resistant models (MPR) are available for solvent applications. Both pumps utilize PTFE diaphragms and PEEK valves for minimal maintenance requirements.

A dual speed selection switch makes these ideal for multiple applications including filtration, drying, degassing and extraction via chromatography packings.

• Ultimate vacuum is <45 mbar
• Standard and chemically resistant models
• Extremely low noise and vibration
• Great for aspirating liquids
• 115/230V wide-range motor

The MP(C) 104Ep offers the end user a powerful vacuum in a very small package. These units are very robust, and they come with a standard two year warranty. The low noise and low vibration make these pumps suitable for any location.

Standard duty pumps (MP) are available for pumping air and chemically resistant models (MPC) are available for solvent applications. The PTFE diaphragms are rated for a minimum of 10,000 hours of run time, which translates into very little maintenance.

Diaphragm Pumps
Features

• Available in standard and chemically resistant versions
• Compact, practical solution for vacuum range 1000 to 1 mbar
• Quick, simple maintenance and service work
• Optimized design for excellent final vacuum
• Oil-free, low noise level

For dry, oil-free applications in the rough and medium-high vacuum range ILMVAC diaphragm pumps are used world-wide in production, research and science. As an economically and ecologically superior alternative to water operated vacuum pumps the ILMVAC diaphragm pump range always offers a versatile and practical solution for many diverse applications between atmospheric pressure and 1 mbar.

ILMVAC diaphragm pumps can be used in a wide range of applications. With components and materials selected for optimal practical employment in laboratory and industry. Also used as regeneration pumps in combinations pumping systems, they fulfill their tasks due to outstanding chemical resistance and stable vacuum parameters. All ILMVAC diaphragm pumps are compactly and functionally designed. Maintenance and service work is fast and easy. ILMVAC diaphragm pumps guarantee outstanding operation and possess a long life span. They work extremely quietly and contamination of process gases with oil cannot arise. ILMVAC diaphragm, pumps are manufactured and tested in accordance with DIN 28 432.

Applications include vacuum distillation, vacuum concentration, molecular distillation, drying ovens, vacuum filtration, and gel drying.

Chemically Resistant Diaphragm Pumps from ILMVAC

Chemically resistant diaphragm pump models MPC, are fully suited to applications where aggressive solvents and acid vapors are present. The diaphragms and other wetted parts are made from compounds of PTFE, PP and PVDF. The pumping and connection heads are carbon fiber reinforced with a small electrical conductivity. This prevents electrostatic loading and minimizes the danger of igniting gas mixtures in the pump by electrostatic discharge.

These chemically resistant, single-stage diaphragm pumps are oil-free and have a wide range of applications between atmospheric pressure and 75 mbar. Each has a compact design, low noise level and simple construction for low cost operation.
