The pumps are produced from one-piece solid and pure PE or PTFE (also conductive). The construction is machined rather than cast. There are fewer stress points so the unit can handle and tolerate mechanical forces better than injection moulded units.

The pumps are designed to cope with harsh process environments where fuming and harsh liquids are present. The Verderair Pure range has been tested to ensure the pump can withstand the demands of manufacturing photovoltaic solar panels where highly aggressive fluids are in use. Other typical industries include the manufacture of semi-conductors, electronics, pharmaceuticals, power stations, refineries and chemical transfer.
The seats and valves of the Verderair Pure double diaphragm pump range can be removed and exchanged without the need to disassemble the pump by removing the plug and access the seat and valve for inspection and maintenance.
