Silicone diaphragms are the key to Pressure Compensating (PC) emitters, especially in topography, which features hills, undulations, and on slopes.

Gulf Rubber Diaphragms are used to endure acidic irrigated water in farms and recycled water for residential applications.

Diaphragms are the heart of the Drippers. Its function is to compensate for the varying pressure loss.

Diaphragms are custom formulated and moulded to target the specific flow rate required of our customers.

Features and Benefits

  • Coefficients of Variation (Cv) are typically less than 5% using the Gulf Rubber Diaphragms.
  • Hardness range is +/- 1 Durometer to ensure consistently throughout the manufacture of millions of such diaphragms
  • Gulf Rubber manufacturers the diaphragms using compression and injection moulding to ensure the best flow rates are achieved through very highly controlled manufacturing conditions and processes.
  • Dimensional tolerances are +/- 0.05mm for thickness and +/- 0.10mm for outer dimensions

Materials

  • Typically produced using Silicone and Liquid Silicone Rubber (LSR)
  • In house development and customization of compounds and products
  • Good long-term stress relaxation, little to no hardness variation, heat ageing and ozone and chloramines resistance.
