Due to its design the LEWA ecodos series already has all advantages of the diaphragm pump

	it is hermetically tight, no metering fluid can escape
	contamination of the metering fluid with drive unit oil is not possible
	the diaphragm pump gently conveys even sensitive fluids
	absolute safe in dry operation
	the very long diaphragm service life (two years!) results in very long service intervals and so very low operating costs
