Membrane Pumps
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 well as in industry, laboratory and education. As an economically and ecologically superior alternative to water operated vacuum pumps the ILMVAC diaphragm pump range always offers a versatile, practical solution for many diverse applications between atmosphere and 1 mbar.
Special characteristics:
- robust
- long lifetime
- very quietly running pump
- optimal initial costs
- compact space saving design
- sandwich diaphragm
- very easy to service
- low operating costs
ILMVAC diaphragm pumps are available
- with different materials for chemical or physical processes
- regulated or unregulated vacuum
- pumping speeds from 300 l/h up to 16 m3/h
- final pressures from 75 down to < 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 combination pumping systems (chemvac), 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 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 DN 28 432.
Ecoflex diaphragm pumps are equipped with a state of the art vacuum control by controlling the pumping speed of the pumps. The vacuum is exactly adjusted to the needs. The vacuum processes run more effective and reproducible. The additional pressure reduction allows the distillation of gas mixtures almost automatically and without fractionated operation. The operation costs can be reduced by 80%. ecoflex diaphragm pumps guarantee a positive economical and ecological balance.
Chemically resistant ecoflex diaphragm pumps (MPC) are resistant to aggressive solvents and acidic vapors. The diaphragms and gas contacting parts consist of PTFE and PTFE Compounds. The pumping and connection heads are carbon fiber reinforced with electrical derivation ability to prevent an electrostatic charging.
