Flotornic pumps have designed a concept in diaphragm pumps called the one nut principle.
Its benefits include: -
Longer lasting diaphragms
A significantly reduced stroke length allows use of thicker / stronger PTFE diaphragms as standard. Nitrile, Viton® and EPDM are also available.
Fifteen minutes to change diaphragms by the removal of just one nut and without disconnecting the pump from the pipework.
Lower cost spares
Less than half the quantity of spare parts than any equivalent pump and interchangeability of most air system parts between different series of pumps.
A unique, patented air system incorporating a bolt on spool valve, including manual override buttons, eliminates costly internal air mechanisms and mid position stall normally associated with Double Diaphragm Pumps.
Greater inherent safety
Plastic parts are kept within metal containment and potential leak paths are reduced to a minimum. Even under ATEX conditions pumps can be maintained 'in the zone' up to Zone I using anti-static PTFE-faced diaphragms.
Materials of construction are :-
Aluminium, Polypropylene, PVC, PVDF, 316 stainless steel,
exotic metals and solid virgin or anti-static PTFE with PTFE,
Viton®, EPDM or Nitrile rubber diaphragms, balls and seals.
Version E = Painted carbon steel
Version S = Stainless steel.
