Air operated 'one-nut' diaphragm pump

The Flotronic 'one-nut' diaphragm pump concept features an innovative design against the traditional styles of diaphragm pumps. Liquid passes through the centre body of the pump, rather then through external manifolds commonly found on other pumps. This concept leads to many advantages which are detailled below

Diaphragm maintenance and cleaning of the main pump chamber can be accomplished by removing a single nut, without requiring removal of the pump from any connected pipe work, and can be carried out in as little as 15 minutes. Removing the air valve is also simple with only 4 bolts requiring removal and as before the pump can remain connected to the fluid lines

Pumps can be manufactured from machined 316 Stainless Steel, aluminium, polypropylene, PVC, kynar (PVDF), and Teflon. Fabricated metal pumps are also availalble. Teflon elastomers are fitted as standard and the shorter diaphragm stroke ensures long life and reduced service costs. Special diaphragms for high temperature, ultra-pure, and high suction applications are also available.

Flotronic pumps can also be fitted with a wide range of optional extras, these include; pump stroke counters, diaphragm rupture protection, and integrated pulsation dampers. Pumps can also be electro or hand polished for a supreme finish for sanitary applications. ATEX certification is also available for use in hazardous areas
