• Diaphragms and seals made of NBR.
• Cast housing with oil-immersed mechanism and transparent plastic tank for visual level check.
• Oil drain plug.
• Pistons with ring for a more effective "oil cushion" system to protect the diaphragm.
• New design diaphragm cutoff system to prevent tearing even under heavy operating conditions.
• Ball sector profile valves for lower flow resistance and improved volumetric efficiency.
• Metal connectors with galvanised finish.
