A casing drain is standard on all these pumps simplifying maintenance by the back pull-out design. Baseplates can be provided in steel or fibre glass. The option of a digital power monitor is also available to detect over and under load conditions. The popular G series of mechanically actuated diaphragm pumps has recently been extended following the introduction of the new GM version. These robust and reliable dosing pumps are particularly suitable for water treatment applications where there is a need for safe and efficient transfer of liquids such as coagulants, caustics and acids.
Multiplexing is possible with the same or different heads, flow rates and materials.
Servos can also be added to permit automatic stroke control. The wide choice of motor options extends to those for use in hazardous areas and others which enable variable speed control. Stroke counting is also possible which means the pumps can be used for batching applications. Single or double mechanically actuated PTFE diaphragms can be specified, whilst stainless steel, polypropylene and PVDF liquid ends are supplied as standard. The pumps also incorporate a variable eccentric system for stroke length adjustment.
