Why Sundyne Genuine Parts for PPI Diaphragm Compressors?
  • Greater Reliability
  • Longer Bearing Life
  • Improved Component Life
  • Warranty Protection
  • Longer MBTM Intervals
  • Only Parts Specifically Designed for Diaphragm Compression Duty
 
Sundyne’s PPI diaphragm compressors deliver total assurance of non-contaminating gas compression. Boasting a leak tight mechanism that features static seals which do not need to be purged or vented, these compressors present absolutely zero leakage threat to the atmosphere, providing an ideal solution for safely handling Hydrogen and other ultra-pure, corrosive or volatile gases.

Don’t Trust Non-OEM Parts:

The safety and reliability of PPI diaphragm compressors can be compromised if non-OEM parts are used. Sundyne makes it easy to obtain every part needed to maintain and keep PPI compressors operating at peak efficiency. Keep an inventory of these parts on hand to maintain reliability & cost savings:
  • O-ring Kits
  • Check Valves
  • Overpump Valves
  • Oil Filters
  • Diaphragms

Check Valves For Diaphragm Compressors:

Pirated or replicated check-valves are not engineered for long-term reliability under high frequency cyclic response and higher operating pressures, making them less reliable for use in PPI compressors. Check valves for PPI compressors use materials that minimize wear, improve sealing and reduce corrosive effects. Process conditions dictate the style of valve specified for a given process.

Hydraulic Inlet Check Valves:

The check valve (located at the inlet of the hydraulic head) prevents back-flow of oil to the injection pump during the compression stroke. This simple but sturdy ball-type valve is specifically designed for PPI compressors. Field proven to provide reliable service over a long period, it features all-metal construction and heat treated materials for high durability and long life.

 
 

Hydraulic Overpump Valves:

This valve controls oil pressure for the compressor’s hydraulic system, and maintains sufficient hydraulic pressure to achieve the specified process gas discharge pressure. Genuine Sundyne PPI parts use a heat-treated metal-to-metal, low-lift poppet & seat that relieves on every stroke. Sundyne/PPI hydraulic overpump valves are field proven to provide thousands of hours of reliable operation.

The Diaphragm – Featuring Enhanced Material Engineering For Maximum Performance:

All aspects of Sundyne/PPI diaphragm design are intended to enhance component life and improve operation, while simultaneously simplifying and reducing the need for maintenance. Because of this, PPI diaphragm compressors will run for years with routine maintenance and oil changes. Constructed from special materials that provide enhanced strength, elasticity and durability, the Sundyne genuine diaphragm is engineered to perform to well over 10 million cycles, offering unprecedented reliability, and peace of mind.
