Metering Hydraulic Diaphragm Pump – API 675 & ATEX
The main feature of this pump is its special sandwich diaphragm and the reliability of the diaphragm rupture detection system. This results in a reliable and robust pump. A rupture means an excess pressure that sends an alarm sign through a pressure gauge or SPDT contact alarm with pressure switch. The pump includes a safety valve to guarantee the diaphragm security against over pressure and an oil recirculation valve.
The regulation can be manual or automatic (4-20mA; Profibus) or pneumatic (3-15 psi).
Accuracy is better than 1% from 10 to 100% of the flow adjustment.
Multiplex version with multiple heads available on request.
There is a wide range of materials available such as HASTELLOY, ALLOY, PTFE, etc.
