4. Clean the surface with damp cloth only to avoid electrostatic charge hazard. Operating Instructions The Teryair Stroke diaphragm pump generates a alternate stroking of the diaphragms against the fluid in the liquid chambers of the Pump. This reciprocatory action is responsible for the fluid being pumped.
Operation and Maintenance Guide DP 25 Metal Series Page 5 Caution: Temperature limitations and diaphragm options An excellent general-purpose diaphragm for use in non-aggressive applications such as water-based slur- ries, well water or sea water. Exhibits excellent flex Neoprene life and low cost. Temperature range -18°C to +93°C (0°F to +200°F) Excellent for applications involving petroleum / oil-based fluids such as leaded gasolines, fuel oils, Nitile non-synthetic hydraulic oils, kerosene, turpentine and motor oils. Temperature range -12°C to +82°C (+10°F to +180°F) Good abrasion resistance. Low cost. Can handle mild acids and alkalis well. Excellent low cost alternative Santoprene to ptfe. Excellent suction capabilites Excellent general purpose diaphragm. Temperature range -40°C to +107°C (-40F to +225°F) Good abrasion resistance. Low cost. . Excellent suc- Hytrel tion capabilites Good general purpose diaphragm. Temperature range -29°C to +104°C (-20°F to +220°F) Excellent for use in applications requiring extremely hot temperatures.
