Product Details Supplier Info More products

A conductive yet non-metallic compound material supplied by RTP Company has enabled US manufacturer All-Flo to produce a specialised version of its 1in (25mm) polypropylene air-operated diaphragm pump.

The Atex-certified 1in pump is designed for use in mining operations thanks to its non-metallic construction and low weight.

RTP, working in partnership with All-Flo and its injection moulder Royal Plastics, trialled a number of materials and a variation of its RTP 100 series glass-fibre-reinforced polypropylene compound was chosen after passing evaluation testing.

The addition of carbon powder provided the conductive properties needed to meet stringest customer requirements.

Key benefits of product application

  • The glass-fibre-reinforced polypropylene compound enables the pump to better resist corrosion from harsh chemicals.
  • According to Paul McGarry of All-Flo, miners have said they appreciate the lighter weight of the pump as they have to carry the equipment down in tight elevators or walk it from hole to hole.
  • The material supplied by RTP worked well with All-Flo’s existing moulds; for Royal Plastics, it was just a case of switching out materials for All-Flo to produce the specialised pump.
