The Welker® LSSM-1 is a sampler designed to extract a representative sample of the flowing product out of a bypass stream and pump it into either a constant pressure or standard cylinder. It is a positive displacement pump with the patented Vanishing Chamber™ collection head at the heart of the unit. It has a double-acting air actuator to drive the sampler and comes standard with ¼" NPT connections. Used separately or as part of a complete sampling system, the LSSM-1 will provide the user with an accurate and representative sample of their product.
