• Diaphragm Options SDP 40 ALX

  Type of Diaphragm	Image	Typical Usage
  Neoprene		An excellent general purpose diaphragm for use in non-aggressive applications such as water- based slurries, well water or sea water. Exhibits excellent flex life and low cost. Temperature range -18 C to +93 C (0 F to +200 F)
  Nitrile		Excellent for applications involving petroleum / oil-based fluids such as leaded gasolines, fuel oils, non-synthetic hydraulic oils, kerosene, turpentine and motor oils. Temperature range -12 C to +82 C (+10 F to +180 F)
  Santoprene		Good abrasion resistance. Low cost. Can handle mild acids and alkalis well. Excellent low cost alternative to ptfe. Excellent suction capabilites, Excellent general purpose diaphragm. Temperature range -40 C to +107 C (-40 F to +225 F)
  Hytrel		Good abrasion resistance. Low cost. Excellent suction capabilites. Good general purpose diaphragm. Temperature range -29 C to +104 C (-20 F to +220 F)
  Viton		Excellent for use in applications requiring extremly hot temperatures. May also be used with aggressive fluids such as aromatic or chlorinated hydrocarbons and highly aggressive acids. Especially where high suction lift is important. Temperature range -40 C to +177 C (-40 F to + 350 F)
  PTFE		Excellent choice when pumping highly aggressive fluids such as aromatic or chlorinated hydrocarbons, acids, caustics, ketones and acetates. Temperature range +4°C to +104 C (+40 F to +220F)
  Note: not all diaphragm options may be available with all pumps. See above for diaphragms available with this pump.
