Why Sealless Diaphragm Compressors


Why a Diaphragm Compressor? 


Provides environmentally safe, leak free, non-contaminating processing of your critical gases.

Sundyne 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 no 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. Built to meet stringent API 618 standards for reciprocating compressors, these machines are available in a variety of flexible configurations and sizes, making them easily customizable to meet the ideal pressure ratio for your application. Backed by our global network of Authorized Service Centers and support staff, Sundyne diaphragm compressors are the reliability focused solution for customers operating in the petrochemical, refining, electron gas, specialty gas and polysilicon production industries.
