Product Components

  1. Pre-set diaphragm bolt and washer made up of 316 stainless steel specially indicated for chemical resistance and longer operation life.
  2. New sealing system between crankcase/head and check valves.
  3. Oversized suction and pressure circuits create a smooth flow of liquid with no loss of pressure.
  4. Diaphragms are designed to handle chemicals and never lose form.
  5. Special check valve design: aspheric section-shaped made up of 316 stainless steel, delivering high volumetric efficiencies.
  6. Die-cast crankcase incorporating a new cooling system.
  7. Oversized oil sight glass to provide constant lubrication and easy reading of oil level.
  8. Internal shaped head design helps ensure suction capability.
  9. Parts in contact with the spray liquid are black oxide anodized aluminum or stainless steel to help provide corrosion resistance.
