Plastic

Plastic pumps are able to move and transfer liquids that would damage or corrode pumps with metal parts. They are resistant to chemicals and lighter than metal pumps, but the downside is that they operate on limited temperature and pressure ratings and may be damaged on impact. The plastic series of Blagdon Pumps are able to move acids, chemicals, adhesives and abrasive materials such as concrete, grout and liquid metals. They are also used for moving petrol, diesel, fuel oil, slurry, sewage ground water, waste water and saltwater, as well as rendering wastes, powders and liquids with a high percentage of suspended solids. Blagdon's plastic pump series includes the following models:

  • • The B06 series of polypropylene and PVDF (polyvinyldiene difluoride), also known as KYNAR, that operate to a maximum pumped liquid rate of 16 litres per minute, maximum operating pressure of 5 bar and a maximum solid particle size of 1 mm. There are options for valve balls to be made of PTFE (polytetrafluoroethylene), Viton and AISI 316 stainless steel.
  • • The B15 polypropylene and PDVF pump series that have a maximum pumped liquid rate of 48 litres/minute, a maximum pressure of 8 bar and particle size of 8 mm. Valve balls can be made of 316 stainless steel and neoprene.
  • • The B25 polypropylene and PDVF series that can move liquids at a maximum rate of 152 litres/minute to a maximum operating pressure of 8 bar and solid particle size of 3 mm.
  • • The B50 series of polypropylene and PVDF pumps that can move liquids to a maximum rate of 530 litres/minute, a maximum pressure of 8.6 bar and a maximum solid particle size of 6 mm.
  • • The B75 polypropylene and PVDF series that can move liquids to a maximum rate of 901 litres/minute, at a maximum pressure of 7 bar and a maximum solid particle size of 18 mm. Valve balls are also available in PTFE and santoprene.
