The Series 1500 Diaphragm Compressors for pressures up to 6,000 psi

Designed for processes engineers requiring reliable operation in the full range of high pressure services

The Sundyne Sealless Series 1500 Diaphragm Compressor is ideal for pilot plant and lesser quantity cylinder filling applications where high purity or hazardous gases are used in lower capacities. The 1500 Series compressor is supplied as standard with an integral electric drive motor and leak detection system.

  • Displacements to 0.025 cfm (0.7 lpm)
  • Inlet pressure: 0-2,450 psi (0-170 bar)
  • Discharge pressures to 6,000 psi (414 bar)

PPI Diaphragm Compressors Series

All 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 ultra-pure, corrosive and volatile gases. Additionally, our diaphragm compressors are designed to isolate the process media from the piston or piston rings with a set of metallic diaphragms, completely eliminating the risk of cross contamination. Most models are built to meet API 618 standards where applicable to diaphragm compressors. These machines are available in a variety of flexible configurations and sizes, making them easily customizable to provide the ideal compressor for your application. Backed by our global network of Authorized Service Centers and support staff, PPI sealless diaphragm compressors are the reliability-focused solution for customers operating in the petrochemical, refining, electronic gas, specialty gas and polysilicon production industries.

Durability

We have thousands of compressors installed in extreme operating environments, such as refineries, petrochemical facilities and immaculately clean research centers; but no matter where they are installed, diaphragm compressors deliver high performance, lubricant- and particulate-free compres- sion of gases and mixtures. Plus, our proprietary Ultrafram diaphragm technology and proprietary cavity design provide unmatched diaphragm life.

Reliability

PPI diaphragm compressors feature heavy duty components custom engineered to ensure reliable operation. We performance test every compressor in the factory and document operating data to meet your specific service and operating parameters.

  • Proprietary designs evolved from years of field experience assures reliability in the most demanding applications and environments
  • Thorough factory testing prior to shipment verifies guaranteed test point
  • Critical components, including the crankcase assembly and connecting rod(s), are designed for long life with minimal maintenance
