According to Serfilco, some of the advantages in converting to this new range of pumps include: All plastic, corrosion resistant air valve - many, which appear similar but have internal metal parts, cause corrosion when the diaphragms rupture; Non-stall operation - PTFE filled nylon pilot sleeve assembly provides un-lubricated, non-stick, non-stall operation; Max flow rates maintained - Even with PTFE overlay diaphragms fitted Serfilco does not have to derate its pumps by up to 20 per cent due to reduced stroke length; and High efficiency, low air consumption - Recycling of exhaust air means Serfilco AOD's are up to 55 per cent more air efficient than similar sized competitors.
